October half term lands on the calendar just as the weather turns properly British: damp mornings, gusty afternoons, and puddles deep enough to swallow a wellie. For most mums juggling budgets in autumn, the coat question becomes urgent around late September, and the shortlist tends to circle the same four names on parenting forums and school gate chats. Regatta, Mountain Warehouse, Trespass and Muddy Puddles all promise the holy trinity of waterproof, insulated and affordable, yet the differences between them at the £60 mark are surprisingly wide once you look past the marketing.
This comparison focuses on real UK stock available at John Lewis, Boots, JoJo Maman Bébé and Amazon UK, checked against the brands’ own outlets and pop up sales. The aim is practical: warmth ratings that actually mean something, hydrostatic head readings you can trust, sizing quirks that catch parents out, and honest guidance on which coat suits a scooter school run versus a soggy weekend at Center Parcs. Every price listed is in GBP and drawn from the current autumn 2026 stock refresh, so it should hold through the half term rush.
How the four brands stack up on price and positioning
Regatta sits at the value engineer end of the market, with core kids’ waterproofs like the Hurdle IV padded jacket landing around £42 to £48 at John Lewis and Regatta’s own outlet. Mountain Warehouse plays a similar game with the Torrent, Turbine and Rocket ranges, most of which drop under £55 during their frequent 40 percent off events. Trespass, based in Scotland, positions itself slightly rougher and readier, with the Snowfall, Verify and Marvelous kids’ coats consistently on Amazon UK between £35 and £58 depending on size and colourway.
Muddy Puddles is the outlier. It is a British specialist that only makes children’s outerwear, and its coats tend to start higher, around £55 to £59 for the EcoSplash and Puddleflex ranges. What you pay for is a narrower fit, longer sleeves designed to grow with the child, and Bluesign certified fabrics that appeal to eco minded parents. On John Lewis, Muddy Puddles frequently appears in the top rated kids’ waterproof lists, which reflects why it has such a devoted following in the two to seven age bracket.
Choosing between them means being honest about the child’s actual autumn use. A five year old who scoots to school in Chiswick has different needs to a nine year old spending three days at a wet Devon caravan park during half term, and the difference is rarely resolved by price alone.
Reading warmth ratings without the marketing fluff
Adult grade warmth ratings, the sort of TOG or fill power numbers you see on duvets and adult puffas, are almost never published on kids’ coats under £60. Instead the four brands rely on descriptors like Thermo Guard, Isotex, ColdHeat and Insulated. This can feel vague, but a useful proxy is the insulation weight, usually printed on the swing tag or product page.
Regatta’s Thermo Guard fill on the Hurdle IV runs at 140 grams per square metre, which is a solid mid weight for temperatures down to around minus five Celsius when layered over a fleece. Mountain Warehouse’s Rocket padded jacket uses a similar 130 gsm synthetic wadding, comfortable for the two to seven Celsius zone that dominates a typical southern English October. Trespass tends to run slightly warmer, with 160 gsm fill on the Marvelous, which suits northern half term breaks in the Lakes or Yorkshire Dales where wind chill matters more than raw temperature.
Muddy Puddles takes a different route. Its EcoSplash coat uses 120 gsm recycled polyester fill, so on paper it is the coolest of the four, but the trade off is a longer cut, tighter cuffs and a fitted hood that reduces heat loss. In real world testing at October temperatures around six Celsius with light drizzle, all four coats keep a moderately active child warm for two to three hours of outdoor play. The Trespass Marvelous wins on standing around, at a Bonfire Night fireworks display for example, while the Muddy Puddles wins on active play where overheating is a genuine risk.
Waterproof millimetres and what actually keeps rain out
Hydrostatic head, measured in millimetres of water pressure the fabric resists before leaking, is where the four brands diverge sharply. A 5,000mm rating is the industry entry point for something calling itself waterproof. Anything below 3,000mm is really just water resistant, useful for a light shower but useless in proper autumn rain.
Regatta’s Isotex 5000 fabric, used across most under £60 kids’ waterproofs, hits exactly 5,000mm and is fine for a school run and short walks. Mountain Warehouse claims IsoDry 5000 on the Torrent shell, which is functionally identical. Trespass steps up with Tres Tex 5000 on the Verify and StormShield 8000 on the Snowfall padded coat, which puts it at the top of the value pile for serious rain. Muddy Puddles publishes a 10,000mm rating on the EcoSplash and Puddleflex, which is unusual at this price and reflects the brand’s specialist focus.
The 10,000mm figure matters more than parents realise. A child sitting on wet grass or leaning against a soaked fence post generates localised pressure well above 5,000mm, which is exactly where cheaper waterproofs start to wick moisture through. If half term involves forest school, camping or coastal walks, the Muddy Puddles rating is the safest bet. For town use and school pickups, 5,000mm across the other three brands is entirely adequate.
Sizing quirks that catch parents out
Every brand runs to its own size chart, and the standard age labels are almost useless as a shopping guide. Regatta sizes small across the range, particularly on the sleeves, so a genuine size five year old often needs the six to seven label. Mountain Warehouse runs closer to true age, though the chest measurement is generous, which suits chunky knits underneath but looks baggy on slimmer builds. The zips on Mountain Warehouse coats can also be stiff for younger children, worth checking in store at their Birmingham or Manchester branches before committing.
Trespass is the most inconsistent of the four. The Marvelous fits true to age but the Snowfall runs a full size large, which parenting forums flag every October. Ordering a size down on Snowfall is standard practice and worth remembering when the Amazon UK reviews look confused. Trespass also uses a slightly shorter body length than the others, so tall children in the seven plus bracket sometimes find the coat rides up when reaching.
Muddy Puddles is famously generous on length. Sleeves and hem are cut long deliberately, with the expectation the child will grow into the coat over one to two autumns. Some parents love this and some find it looks oversized in the first season. The brand publishes actual height ranges on every product, not just ages, which makes online ordering from John Lewis or the brand’s own site far more reliable than the competitors.
Real world features that earn their price
Beyond the headline warmth and waterproof numbers, the practical touches separate a good coat from a great one at this price point. Reflective piping on the sleeves and back matters hugely for autumn school runs in fading light, and Regatta and Mountain Warehouse both include it as standard on most under £60 lines. Trespass includes reflectives on the Marvelous but not the Snowfall, which is an odd omission given its target use.
Hood construction is another quiet differentiator. Muddy Puddles fits a shaped, three panel hood with a peaked brim that actually keeps rain off the face, while the other three use flatter, cheaper hoods that flap and let water in during proper downpours. For scooter and bike use, the Muddy Puddles hood is measurably better, and mums who commute this way often cite it as the reason they upgrade.
Pocket depth, zip garages, chin guards and cuff design all vary. Regatta’s fleece lined pockets on the Hurdle IV are the warmest of the four for cold hands. Mountain Warehouse Torrent shells have taped seams and storm flaps that punch above the price. Trespass adds a mesh lined vent on the Snowfall for breathability during running, which is genuinely useful for boisterous kids. Muddy Puddles keeps the pockets minimal but adds elasticated inner cuffs, which stop drips reaching sleeves on any coat labelled EcoSplash.
Stock realities at John Lewis, Boots, JoJo Maman Bébé and Amazon UK
Where you buy matters almost as much as what you buy. John Lewis holds all four brands, though Trespass and Muddy Puddles are the strongest for stock breadth online, with click and collect usually available within two days. The John Lewis two year guarantee applies across the range and is worth the small premium against Amazon UK on identical SKUs.
Boots carries Regatta and Mountain Warehouse in selected larger stores and online, usually with Advantage Card points that shave the effective price by two to four percent. Stock rotates quickly in October and it is worth checking mid month before half term demand strips the popular sizes. Amazon UK carries all four brands but with wildly variable third party sellers, so sticking to Sold by Amazon or Sold by the brand’s own storefront avoids the counterfeit risk that has caught out parents on Muddy Puddles in particular.
JoJo Maman Bébé stocks a curated Muddy Puddles range and its own Puddle Suit lines, which sit around the £55 mark and offer a genuine alternative to the big four. For toddlers under age four, the JoJo Puddle Suit competes credibly with the Muddy Puddles Puddleflex and is often available at a small discount to loyalty scheme members. Sign up ahead of half term to catch the mid October promotional codes that reliably drop.
Which coat suits which half term plan
A city half term of museum visits, indoor play and short outdoor bursts calls for a lighter, packable option. The Regatta Hurdle IV or Mountain Warehouse Rocket at £42 to £48 hits this brief and fits into a backpack when the day warms up. Both are washable at 30 degrees, which matters when hot chocolate happens.
A country half term of woodland walks, beach visits and stately home grounds needs something more substantial. Trespass Snowfall at £54 to £58 offers the warmest fill and taped seams that handle sudden downpours, though the poor reflective coverage means keeping high vis accessories in the boot for dusk. Alternatively the Muddy Puddles Puddleflex at £57 to £59 pays for itself if the child has a younger sibling coming through, as the construction easily survives two seasons of hard wear.
Adventure half terms of proper hiking, camping or wet weather sports demand the top spec. Only Muddy Puddles EcoSplash and Trespass Snowfall really qualify at this price, and between them the Muddy Puddles wins on rain and the Trespass wins on cold. Layering a fleece or fleece lined body warmer under either coat handles temperature drops below five Celsius without spending more on a heavier standalone jacket.
Layering strategy that stretches a £60 budget further
The temptation with a limited budget is to buy the warmest single coat available and hope it covers all conditions. In reality a mid weight coat plus a good fleece or gilet outperforms a single heavy jacket across the temperature range October actually delivers, from twelve Celsius on a sunny midday to two Celsius on a frosty early morning. A £48 Regatta Hurdle IV worn over a £15 Mountain Warehouse Camber fleece handles the full October range better than a £58 Trespass Snowfall worn alone, particularly for active play where regulating temperature matters.
Layering also solves the puddle jumping problem, where a child returns home with a wet base layer even inside a technically waterproof coat. A moisture wicking base layer under the fleece keeps skin dry when the shell is compromised by a hood down moment or a sleeve dip in the stream. Uniqlo Heattech Kids at around £10 to £14 is the popular choice, and it lasts two winters if the child does not grow too fast between them.
Trousers are the forgotten piece of the autumn wardrobe. Waterproof over trousers from Regatta or Muddy Puddles at £22 to £34 keep the puddle line at the ankle rather than the knee, and mean the coat can be lighter without the child getting wet legs. For half term walking holidays this combination is more effective than trying to cover everything with a single expensive coat.

Frequently Asked Questions
Which of these four coats is genuinely warmest?
The Trespass Snowfall wins on fill weight at 180 gsm and holds heat best when the child is standing still, at a football touchline or fireworks display for example. For active play where overheating matters, the lighter Muddy Puddles or Regatta actually feel warmer because they breathe better and reduce clammy sweat that then chills the skin.
Is a 5,000mm waterproof rating enough for October in the UK?
For most parents in southern and central England, yes. A 5,000mm rating handles typical autumn showers and light persistent drizzle. If half term involves the Lake District, Snowdonia, Devon coast or Scottish Highlands, or if the child sits or lies on wet ground for forest school, upgrade to at least 8,000mm from Trespass Snowfall or 10,000mm from Muddy Puddles.
Are the Muddy Puddles coats worth the extra £10 to £15?
For parents planning to hand the coat down to a younger sibling, or where the child spends serious time outdoors, yes. The build quality holds up over two winters and the 10,000mm rating removes anxiety about wet weather. For a single season, town based use, the Regatta or Mountain Warehouse options do the same job for less.
How do I check if my child’s coat has lost its waterproofing?
Sprinkle water from a bottle over the shoulders and back. If it beads and rolls off, the durable water repellent finish is intact. If it soaks in and darkens the fabric, the coating has failed and needs reproofing with a wash in product like Nikwax Tech Wash followed by TX Direct. Both are available at John Lewis and most outdoor shops.
Which brand is best for eco conscious families?
Muddy Puddles leads clearly on this. The EcoSplash and Puddleflex use recycled polyester, Bluesign certified fabrics and PFC free DWR finishes. Regatta has an EcoBrite range in some styles that uses recycled content, but it is not consistent across the under £60 line. Trespass and Mountain Warehouse have minimal published sustainability credentials at this price.
Should I buy in store or online?
For sizing, in store is safer for a first purchase from any of these brands, particularly Trespass. Once the family knows how a brand fits, John Lewis online with free click and collect is efficient. Amazon UK is fine for repeat purchases of a known SKU, provided the seller is verified. Avoid ordering from unfamiliar sellers on Trespass Snowfall, which is the most counterfeited of the group.
What about hand me down coats from older siblings?
Reproofing an older coat with Nikwax restores waterproofing for a small outlay, usually £8 to £12. Check the seam tape has not lifted, particularly at the shoulder and back seams where wear concentrates. If seam tape is peeling, the coat is at end of life for wet weather use but fine as a padded winter layer over a shell.
Is JoJo Maman Bébé‘s own Puddle Suit a serious alternative?
Yes, particularly for toddlers up to age four. The Puddle Suit is a full body waterproof that outperforms separate coat and trouser combinations for muddy play, and the pricing at £55 to £59 competes directly with Muddy Puddles Puddleflex. Older children generally prefer the separates format from age five up.
