Keeping children dry does not have to cost a fortune. The junior waterproofs here are some of the cheapest options available at Go Outdoors for 2026, yet they still offer sensible protection for school runs, playground puddles and soggy campsite adventures.
We have focused on budget-friendly suits and jackets that balance low price with practical coverage, easy wear and simple care. They are not designed for full-on mountain days, but they are more than up to the job for most families.
Each pick has its own strengths, from ultra-low-cost full suits to lightweight stowaway jackets and fun prints that encourage kids to get outside whatever the forecast. It is not just about the very lowest sticker price, but about what you actually get for your money.
These recommendations are based on careful comparison of real product details, prices and brand track records rather than simply pulling out the very cheapest items. We look closely at design, coverage and practicality, because a bargain is only worth it if it keeps your children genuinely comfortable outdoors.
We pay attention to how well-known outdoor brands approach their junior ranges, and how their budget lines compare with the rest of the market. That helps us filter out gear that looks cheap for good reason and highlight options that feel like smart, everyday buys.
Our aim is to steer you towards kids’ waterproofs that make sense for family life in the UK: easy to throw on, simple to pack for weekends away and robust enough to justify the spend, even at the lower end of the price scale.
We started by looking at the most affordable junior rain jackets and suits available at Go Outdoors, focusing on the models that sit firmly in the budget bracket. From there, we narrowed the field to pieces that still offer sensible features for wet UK weather, such as good coverage, a practical hood and a fabric designed to shed showers.
We favoured established outdoor brands that have a long history of making reliable entry-level waterproofs. That usually means better pattern cutting, more thoughtful details and more realistic expectations around what the garment can handle.
Within the shortlist, we looked for a mix of one-piece suits and separate jackets so you can choose what suits your child’s age and activity level. Some options are rock-bottom on price, while others cost a touch more but give you added versatility or a design that kids are more likely to wear without protest.
Every product here is cheap, but not so cut back that it feels like false economy. They are here because they deliver decent performance for the money.
Below you will find our top budget picks for keeping children dry in 2026. Each one earns its place by offering good value at the lower end of the price range, whether that is through full head-to-toe coverage or a packable layer you can stash in a school bag.
Some are the absolute cheapest full suits available, perfect for puddle-loving youngsters. Others cost a few pounds more but offer extra flexibility or fun designs that make wet days feel like part of the adventure.
A simple, great-value one-piece waterproof suit from Peter Storm, giving head-to-toe protection for kids who love puddles and muddy play without stretching the budget.
For around £15, this Peter Storm Kids’ Waterproof Suit is one of the cheapest ways to get full-body rain protection for children. The one-piece design helps stop water sneaking in between jacket and trousers, which is ideal for younger kids who sit, crawl and splash in wet grass and puddles. Being from a long-established outdoor brand, the cut is usually practical, with enough room for warm layers underneath without feeling restrictive. It is a straightforward, no-nonsense suit that does exactly what most families need on wet UK days: keep the worst of the weather off at a very low cost.
Being a very budget-friendly suit, the fabric is unlikely to be as breathable or tough as more expensive technical kids’ waterproofs, so it may feel warm and clammy if your child runs hard in mild weather. Taller or fast-growing children might outgrow the length fairly quickly, so it is worth checking sizing carefully rather than assuming they will get several years out of it.
This suit is ideal for younger children who love splashing in puddles, playing in wet playgrounds and joining family camping trips, where full coverage matters more than high-tech features. It suits parents watching the pennies who still want something that keeps clothes clean and dry without fuss. If you want a straightforward all-in-one that can live by the door ready for any forecast, this is a strong low-cost option.
A lightweight stowaway waterproof jacket that packs down small, ideal as a just-in-case layer for school bags and family days out at a very low price.
The Freedomtrail Kids’ Stowaway Waterproof Jacket is all about convenience and price, giving you a compact layer that is easy to stuff into a school bag or daypack. At around £16 it barely costs more than a few takeaway coffees, yet still offers a simple barrier against showers and blustery walks. The stowaway design means it will not clutter the hallway or suitcase, which is handy for families tight on space. As a standalone jacket it is also more versatile than a suit for older children who do not want to commit to full waterproof trousers every time they step outside.
As a lightweight stowaway jacket, the Freedomtrail design is more about packability than heavy-duty storm protection. It may not cope as well with prolonged, driving rain as a thicker, more technical shell, and you will need separate waterproof trousers to keep legs dry. The very simple construction can also feel a bit basic compared with pricier kids’ jackets.
The stowaway jacket is a great pick for older kids who mainly need a light layer for school, day trips and occasional showers rather than full-on foul weather. It is particularly useful for families who want something that can be thrown in a bag “just in case” without adding bulk or weight. If your budget is tight and you prioritise flexibility and packability over absolute weather protection, this fits the bill.
A unicorn-themed version of Peter Storm’s kids’ waterproof suit, adding a playful print to practical all-in-one rain protection for only a little more money.
The Peter Storm Kids’ Waterproof Suit Unicorn takes the practical one-piece design and adds a fun unicorn theme that many children will actually want to wear. For roughly £20 you are paying only a small premium over the plain version for a design that may avoid battles at the front door when the weather turns. Full-body coverage helps keep clothes underneath clean and dry, making it particularly useful for camping trips and after-school park visits. Being from the same dependable brand, you get a familiar fit and sensible detailing that works in everyday family life.
You are paying a little extra for the unicorn print, so in pure pounds-per-feature terms it is not quite as cheap as the plain suit. As with other value suits, breathability and ultimate durability will not match premium children’s outdoor gear, so it is better suited to typical family use than regular mountain adventures. Older children may also outgrow the playful design taste-wise quite quickly.
Choose the unicorn suit if your child loves bright, playful designs and you know they are more likely to wear something with a bit of character. It is well suited to nursery and primary-age children who spend lots of time outdoors in all seasons, from forest school to weekend walks. For parents willing to spend slightly more than the absolute minimum to avoid battles over putting a waterproof on, it is a smart compromise.
A moon-and-stars printed full suit that keeps children dry from neck to ankle, offering solid coverage and good value for frequent wet-weather play.
The Peter Storm Kids’ Moon Stars Suit delivers the same head-to-toe protection as the other full suits, but in a smart moon-and-stars print that looks a touch more grown-up while still being fun. At around £20 it offers strong value for a garment that can handle regular wet play, school runs and soggy weekend walks. The all-in-one design helps parents avoid damp waistbands and muddy gaps between jacket and trousers, which is especially helpful with smaller children. Its combination of design, coverage and price makes it a very solid choice if you expect a lot of use.
Although it offers good coverage for the price, this is still a budget suit, so you should not expect the fabric or zips to feel as robust as high-end kids’ shells. In sustained heavy rain or rough play on abrasive surfaces, it may show wear sooner than more expensive options. The one-piece design is also less convenient for quick toilet stops compared with a separate jacket and trousers.
The moon-and-stars suit is a strong choice for families who expect frequent wet-weather outings and want a fun but slightly more subtle print. It suits children who spend a lot of time outdoors at school, clubs or camps, where reliable coverage matters and a full suit can save multiple outfit changes. If you want something that still feels affordable but can stand up to regular use, this is a sensible pick.
A unisex packable waterproof jacket from Peter Storm that offers versatile, everyday rain protection for kids who do not need a full suit.
The Peter Storm Kids’ Unisex Packable Waterproof Jacket offers a versatile solution for families who want one jacket that can handle school, walks and holidays without costing a fortune. Priced at about £20, it undercuts many technical junior shells while still providing a windproof and showerproof outer layer. The packable design means it can live in a rucksack or under a buggy without taking up much space, making it easy to always have a layer to hand when showers roll through. As a unisex style, it is an easy piece to hand down between siblings, stretching your budget further.
As a packable value jacket, it is likely to prioritise lightness over heavy-duty reinforcement, so it may not be the best choice for constant rough play or regular scrambling over rocks. It only covers the upper body, so you will need separate waterproof trousers for full wet-weather protection. Breathability is also likely to be basic, which active children may notice on warmer days.
This unisex packable jacket is ideal for families who want one do-it-all waterproof layer that can move between school, weekend walks and holidays. It is a good match for older children who do not need or want a full suit but still need a reliable outer shell when the weather turns. If you are looking for an affordable jacket that can easily be passed down to siblings to maximise value, this is a strong contender.
