Fun Suit

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, cat poo (oops), 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.

Winter Sports go to

We absolutely love our All-Weather Fleece Onesie - Navy | Waterproof Windproof Eco. Our 9month old son wears it whenever he is venturing outside. Being the youngest of 4 means his Saturday mornings and weekday afternoons are spent at his big brothers football games and practices. We love knowing that he is snug, warm and dry. Thank you!

Great birthday present

Got these beauties for my 2 year old twin boys. The suits have kept them dry and warm at older brother's soccer games and for other wet and muddy playground adventures. Bonus, the bright blue pattern makes it easy to keep my eye on them as they roam. Only downside is that the extra waterproofing on the bum is not conducive to sliding down slides! But that's an easy fix :)

Very practical

We use it almost every day. Keeps my little one so warm. Don’t even need too many layers underneath. An amazing onesie for little kids.
