Which Rainsuit Is Right for Your Child?

All week, I have stood with parents in the rain gear corner discussing the differences between each rain suit, and if you’re online you're probably doing the same thing.

There are many different types of rain suits, or jumpsuits, to do many different functions. Some are designed for warmth, some are designed for comfort, some offer light waterproofing while others offer sealed and secure seams. 

There are a few terms you should know before we dive into our 2026 spring collection… 

What does 10,000 mm waterproof really mean?

The 10,000 mm rating comes from a lab test called a water column test.
It measures how much water pressure fabric can handle before water pushes through.

• Imagine a clear tube placed on the fabric.

• The tube is slowly filled with water.

• If the fabric holds back 10,000 millimetres (10 metres) of water before leaking, it earns a 10,000 mm waterproof rating.

This is usually the gold standard for everyday children’s rain gear - it’s not meant for hours kneeling in puddles or hiking in rainstorms. 

Sealed vs. Welded vs. Unsealed Seams in Rainsuits

1. Unsealed seams -  The fabric may be waterproof, but the stitched seams are left exposed.

2. Sealed (taped) seams - A waterproof tape is applied over the stitching on the inside of the garment.

3. Welded seams - Fabric panels are fused together with heat instead of stitched — so there are no needle holes at all.

Comparing Rain Gear Materials & Waterproof Coatings

1. Polyester with Polyurethane (PU) Coating - A layer of polyurethane is painted or laminated onto polyester fabric to block water.

2. Recycled Polyester with TPU Lamination or Membrane - A TPU (thermoplastic polyurethane) film is laminated or bonded to recycled polyester. Sometimes paired with a separate waterproof membrane backing.

3. Bionic-Finish® Eco DWR Coating - A surface treatment that makes water bead and roll off fabric — but it is not the main waterproof barrier.

With those basics in mind, let’s take a look at the one piece rain suit options we have in store this spring. Sold out? Ask us about restocking your favourite colours, sizes and styles. Jan & Jul is one of our best selling day-to-day and super easy for us to bring back in shop. 

One-Piece Kids’ Rainsuit Comparison

The truth is, there’s never one single best rainsuit.
Each style is designed to solve a different need, for different weather, different kids, and different budgets.

If you’re tired of the limited performance of a basic Muddy Buddy, the simplest upgrade is usually a Jan & Jul suit. They offer stronger waterproof coating, and a nice trim fit that works up to a size 6-8Y. The fleece suit is often loved by families through the year, layered for snow! 

The Paihola is arriving soon and brings a full size range with durable TPU lamination and a polished, premium feel. It’s built to impress — but it does come with a higher price point. In generally, I'll recommend the Reima Lammikko rain pants to most families who no longer need a full body suit and ready to consider an overall. 

And from time to time, we’re lucky enough to see Wheat rainsuits come through. With their welded seams, they’re honestly one of my personal favourite options for serious wet-weather protection, and come in under $100 - I'm not sure if I ordered them for this year... 

If your child isn’t the type to lie down in puddles and you simply need reliable outdoor warmth and rain protection, softer shell options like the Nurmes, Mjosa, or the Therm All-Weather series can be fantastic everyday choices.

We also occasionally receive second-hand rain gear. It doesn’t happen often — and when it does, it sells out quickly. If you want to catch it, follow the collection and keep an eye out. And yes, we do accept rain gear for consignment too, though waterproof materials can break down over time, especially simpler polyurethane coatings or aging seam tape.

Taking care of your rain gear makes a big difference.
That’s why we carry Gear Aid products to help you wash, repair, and re-waterproof your gear. From gentle detergents to waterproofing spray. 

Be sure to read the care instructions in your garmet because each waterproofing application and style has different recommendations from gentle dryer use, to wiping clean, and more.
