Trespass Unisex Kids Button Waterproof Rain Suit 5-6 Review: a lightweight puddle suit that mostly does the job

I’ve been using this Trespass unisex waterproof rain suit in size 5–6 (navy blue) with a puddle-obsessed kid, and I’ll be straight: it’s a practical, no-frills suit that keeps them dry most of the time, with a couple of weak spots you should know about. If you’re expecting high-end outdoor gear, this isn’t it. If you just want something they can trash at the park and forest school, it’s pretty solid.

What pushed me to try it is the mix of a full-length zip, lightweight fabric, and elastic cuffs. I was tired of wrestling my kid into stiff waterproof trousers and a separate jacket. With this, it’s one piece, zip up, done. On hectic school mornings or when it suddenly starts pouring, that alone is worth a lot.

In day-to-day use, it’s more of a rain shell than a warm suit. There’s no lining, no insulation. So you need to think in layers: joggers and a jumper underneath in cooler weather, or just light clothes for warmer rainy days. The good point is that it doesn’t make them walk around like a Michelin man, they can still climb, run, and go down slides without complaining.

Overall, my first impression after a few wet school runs and a couple of muddy park sessions: good value for money, keeps the worst of the rain and mud off, but it’s not perfect. The ankle area is the weak link if your kid is really going hard in deep puddles, and the fabric feels more like everyday use than hardcore hiking gear. But for the price, I was honestly happy with how it performed.

Looking at the price vs what you actually get, I’d say this Trespass rain suit offers good value for money, as long as you’re clear about what it is: a lightweight, unlined rain shell for everyday kid use. It’s not cheap throwaway rubbish, but it’s also not the top-tier outdoor gear that costs double or triple. The Amazon rating of 4.6/5 with over 2,600 reviews kind of says the same thing: a lot of parents find it does the job well enough for the price.

What you’re paying for is mainly:

• Convenience – one-piece, full-length zip, easy on/off
• Decent waterproofing – especially on torso and arms
• Lightweight and packable – easy to carry for trips
• Machine washable – simple to clean after muddy play

If your child is in forest school, nursery, or just constantly outside, this is a cost-effective way to keep their normal clothes from being destroyed by mud and rain. You’ll probably get a full season or two out of it before they either outgrow it or you notice wear. For the price bracket, I’m comfortable recommending it, with the ankle caveat.

If you live somewhere with really harsh weather or your kid is doing serious outdoor activities (long hikes, snow, very cold and wet conditions), I’d spend more on a more technical suit. But for standard UK-type rain, school playgrounds, and weekend adventures, the value is there. It’s a practical, budget-friendly tool, not a fancy piece of kit, and used that way, it makes sense.

The main design win here is the full body-length zip. In practice, that means you lay the suit out, your kid steps in, pull it up, zip, done. Compared to separate waterproof trousers and a jacket, this is just faster and less drama. On a wet morning when you’re trying to get out the door, that matters. The zip itself feels smooth enough – I didn’t have major snagging issues, and my kid could eventually pull it up alone with a bit of help at the bottom.

The elasticated waist at the sides helps the suit not look like a big bin bag. It pulls in slightly around the middle, so there’s room for a jumper but it’s not flapping around. During play, the suit stayed in place pretty well – no constant hitching up or sagging. The cuffs at the wrists are snug but not tight, so they sit nicely over thin gloves or under the cuffs of a jumper. That part works well and does help stop water trickling down the arms.

The ankles are where the design shows its limits. They’re elasticated, but not super tight. If your kid is just walking in the rain or splashing shallow puddles, it’s fine. Once they start stomping hard in deeper puddles, you can get some water creeping up the legs, especially if the trousers underneath are a bit long. One of the Amazon reviewers said the same – the cuffs could be tighter. I agree: a simple adjustable strap or stronger elastic there would make a big difference.

The hood is grown-on and sits okay – it doesn’t constantly fall off, but like most basic hoods it doesn’t move perfectly with the head. Over a beanie or a cap it’s fine. There’s no peak or wire, so in heavy sideways rain it’s not perfect for visibility, but for normal drizzle and showers it does the job. Overall, the design is very much: keep it light, simple, and easy to put on. No bells and whistles, but for everyday kid use, that’s often enough.

Comfort-wise, my kid didn’t moan about wearing it, which is already a win. The suit is very lightweight, and the regular fit with elasticated sides means they can move freely – running, jumping, climbing frames, sitting in the sand, all without that stiff plastic feeling. There’s no lining, so the inside is the same smooth shell material. Against bare skin it’s not scratchy, but I still prefer putting at least a long-sleeve top and leggings or joggers underneath.

Because it’s just a shell, temperature control is all about layers. On a cool, wet day, I’d put a fleece or hoodie and thicker trousers under it. On a milder rainy day, just normal clothes. It doesn’t add warmth by itself, which I actually like, because you can use it nearly all year round. In warmer weather, if the kid runs a lot, they can get a bit sweaty inside – it’s not some fancy breathable membrane, just standard PU-coated fabric. But I didn’t notice them coming out soaked in sweat after normal park sessions.

The elastic at the wrists and ankles is generally comfortable – not too tight, no red marks after taking it off. The neck area also feels okay: no rough seams rubbing under the chin. The hood is light and doesn’t pull the suit back. My kid tolerated the hood pretty well, especially over a hat. Without a hat, in heavier rain, a bit of water can still sneak in at the face, but that’s normal for this type of hood.

In practice, my main comfort tip: treat this as a waterproof shell to go over comfy clothes. Don’t rely on it as a standalone outfit unless it’s quite warm outside. Used that way, it works well – the child stays dry enough, can move naturally, and you’re not fighting them to keep it on. For long outdoor days (forest school, camping), I’d just make sure to add good base layers and maybe thicker socks or wellies that come up high to cover the slightly loose ankles.

The suit is made from a thin polyamide / polyester shell with a PU (polyurethane) coating. That coating is what makes it waterproof. In practice, this means water beads off nicely when it’s new, and after several rainy outings my kid stayed dry on the torso and arms. It’s clearly more than just “shower resistant” – it handles proper downpours fine as long as the water isn’t pouring in from the cuffs or neck.

Because it’s lightweight, the fabric is flexible and not stiff, so kids can move easily – running, climbing, crouching in mud, all okay. It’s also not noisy like some cheap plastic suits that rustle loudly with every step. On the downside, you can tell it’s not heavy-duty. I wouldn’t trust it to survive months of constant crawling on rough concrete or gravel without eventually showing wear, especially at the knees and bum. For normal park grass, forest school, and general outdoor play, it’s fine.

One thing I liked: the material dries fast. After a wet session, I could hang it up and it was usually dry by the next morning, sometimes faster. That’s handy if you’re using it for nursery or school several days a week. It’s also machine washable, which I tested a few times. A gentle wash didn’t seem to damage the waterproofing straight away, but like all PU-coated gear, I wouldn’t over-wash it if you don’t need to. A wipe down with a cloth after muddy days is often enough.

Overall, the materials feel decent for the price point: light, properly waterproof on the main panels, and comfy enough that my kid didn’t complain. Just keep in mind it’s a shell, not a padded snowsuit, and it’s not meant for heavy abrasion. If your child lives on their knees on tarmac, you might want something beefier or plan on replacing it after a season.

After several weeks of regular use – school runs, playground trips, muddy fields – the suit has held up better than I expected for a light shell. The seams are still intact, the zip still runs smoothly, and there are no obvious tears. The knees have some light scuffing from crawling and kneeling, but nothing that affects performance yet. For a product in this price range, that’s pretty decent.

I’ve machine washed it a few times on a gentle cycle, plus lots of quick wipe-downs with a damp cloth after muddy days. The colour (navy) hasn’t faded noticeably, and the fabric hasn’t gone stiff or cracked. The waterproofing still seems fine – water still beads on the surface. Long term, like any PU-coated gear, it will probably lose some of its waterproofing if you over-wash it or tumble dry it, so I’d stick to air drying and washing only when it’s really dirty.

The elastic at cuffs and waist hasn’t blown out yet; it’s still springy. That’s usually one of the first things to go on cheaper kids’ gear, so I was watching for that. So far, no obvious loosening. The ankle elastic was never that tight to begin with, so it’s hard to say if it’s changed much, but it hasn’t become worse over a few weeks.

Realistically, I see this as a one or two-season piece, depending on how hard your child is on clothes and how fast they grow. For forest school twice a week plus weekend use, I’d expect it to last a school year without major issues, then maybe start to look a bit tired – which is acceptable for the price. If you want something that survives multiple kids over years, you probably need a heavier-duty brand. For a single kid or to pass down once, this seems solid enough.

This is a one-piece, lightweight rain suit with a grown-on hood and a full front zip that goes pretty much from the neck down to the leg. Size 5–6 is aimed at kids around that age range, and the brand offers it from 6–12 months up to 7–8 years, so you can basically kit out siblings in different sizes. The colour I had is navy blue, which is simple and practical – hides mud reasonably well and doesn’t scream “look at me” like some neon suits.

The suit is unlined and made from a thin shell fabric (listed as polyamide / polyester with PU coating). Translation: it’s there to stop rain and mud, not to keep your kid warm. The weight is only about 0.24 kg, so it’s very light, easy to stuff in a bag or under the buggy. It’s rated as regular fit and honestly that’s accurate – roomy enough to put a fleece underneath, but not so huge that they’re drowning in fabric.

You get elasticated cuffs, ankles and side waist, plus the hood is attached (not removable). The closure is a zip, not poppers, which I prefer: quicker and less faff when you’re trying to dress a wriggly child. There are no fancy extras like reflective strips, pockets, or reinforced knees on this model, so it’s quite a basic setup. That’s not a dealbreaker, but worth knowing if you were expecting more technical features.

In terms of general positioning, it feels like a solid mid-range budget rain suit. Not bargain-bin flimsy, but also not the premium brands you see at outdoor shops for double the price. Judging by the Amazon rating (4.6/5 with a lot of reviews), plenty of people are happy with it for normal use: school, park, forest school, holidays. My experience lines up with that: a good everyday shell rather than a specialist piece of gear.

On the waterproofing front, I’d say it’s properly rainproof on the main body, with one clear weak spot: the ankles. On several rainy walks and some full-on puddle sessions, my kid’s upper body and legs stayed dry where the fabric covered them properly. The PU coating does its job, and water just runs off. I never had an issue with water seeping through the fabric itself during normal use.

The problem shows up when kids start really stomping in deeper puddles. Because the ankle elastic is not super tight, water can splash up and creep inside, especially if the suit leg rides up a bit over the wellies. One Amazon reviewer said exactly this – the expandable trouser cuff is still too loose. I had the same experience: after some intense puddle jumping, the socks and lower trouser legs underneath were damp, even though the rest of the outfit was dry. If your child is more of a walker than a puddle warrior, you might never notice this.

For general use – school run, park in light to heavy rain, forest school in wet grass – it’s effective. It stops mud and rain from soaking their clothes, and it’s easy to hose or wipe off afterwards. It also works well as a windbreaker because the fabric doesn’t let much air through. Just don’t confuse it with a snow suit: in cold, wet conditions you’ll still need warm layers underneath and maybe a hat and scarf for longer outings.

So in practice, I’d rate the effectiveness as: very good for the price on the torso and arms, decent on the legs, and a bit weak at the ankles if your kid is a puddle maniac. If you pair it with high wellies and maybe tuck the suit legs properly inside or outside the boots, you can reduce the issue. But out of the bag, that’s the one area where it’s not perfect.
