Outdoor clothing brands for rugged outerwear
Reima is a Scandinavian brand offers well-made outdoor clothing and outerwear for kids who spend lots of time in nature, in cool climates. Lots of great stuff for snow and rain especially. Check out their jumpsuits.
Polarn O. Pyret is another Scandinavian brand offering “comfortable, high-quality childrenswear” with a “play-friendly design”. Their clothing is better for long/lean kids, from what we’ve experienced.
