Size chart

The measurements below show the 'perfect' size for the garments. If your child is in between these specified measurements (primarily for height) we recommend to go with the next size up to allow for growth. 

As our products are outerwear, they are a generous fit across the body - this will allow for 1-3 layers and larger body types, and all of our waistbands are elasticated for easy fitting. The most important measurement is height as this determines the sleeve/pant length.

Scroll down for diagrams on how to measure your child, and at the bottom of the page we have a link to our actual garment measurements if you would like to compare to items at home.

Machine washable and dryer safe!

Just throw your Therm garment in the wash with your normal load - we recommend a warm wash with liquid detergent, not powder. 

Plus all of our garments love the dryer! In fact the dryer is needed for the waterproof coating. If your Therm garment doesn't seem as waterproof as it was, (or the SplashMagic pattern isn't appearing well) just dampen it again and dry it fully in a medium to hot dryer. 

IMPORTANT: Don't forget to zip up all zippers before washing and drying!

    No seriously! You need it in your life! I live right by the lake in Chicago, it’s very windy and cold. I don’t have a car, so I carry my 10m old son in a carrier everywhere I go. This helps keep him warm and dry so I don’t have to try and layer anymore with bulky items that would make it harder than it already is for a single parent w a baby.

    We call this the fun suit. It's only worn when there is fun to be had. The fun suit is a fun enabler. It's been worn in wet grass, sand, mud, frost and snow. It's easy to wash (rinse it and throw it in the washing machine). It dries super fast. We sized up so that it can be thrown on over anything and everything. Would 100% recommend. Looks awesome too.

    I have a 1 year old and live where it snows. It's soooo hard to find something that is cute and stylish while also preventing water from soaking her clothes.
    This year she is walking and running around so bought the size up and let me tell you it's amazing. She played in the snow and puddles for hours.

    We live in Texas where the winter can get chilly, but not sub-zero. This suit is perfect. I can put it on my busy toddler quickly and easily, which I love. We just use it in place of a coat, that way I’m assured his whole body is warm, not just his upper half. The outer material makes it winproof which is great because it gets very windy here. It’s such a nice quality little suit! I’m a picky, slow to decide shopper and I’m really happy with my purchase!

    I bought this for our son to wear in rainy Ireland. It was an absolute Godsend! He wore it everywhere just in case there was a pop up shower. He was never too hot because the material is breathable. I would definitely recommend this product.

    Great!

    Easy to get on and off over clothes and keeps our daughter dry and warm. Room to grow into it so will likely last through 2 years of fall and winter wet PNW weather. Ordered her size now so no need to size up as these are a roomy fit.

    Perfect for the PNW

    We have played outside so many times in this thing! Love the fold over hands and feet for my crawling guy. Reinforced knees and butt mean he can play harder without worrying holes into the fabric. Perfect weight for PNW fall/winter but size up if you hope to layer for cold climates.
