7Summits Kids

Size Guide

The 7Summits jumpsuit is unique in many ways, but most importantly, our collaboration with mountaineer Mike Hamill and Climbing The Seven Summits. Last year we partnered with Seven Summits to donate from each sale to the Tiger of the Snows Fund, which supports Sherpas who were out of work during the pandemic. As you can imagine, with no international travel, Sherpas have lost their only source of income.

You can feel good about yourself while you chill is this high quality onesie. The 7Summits comes with many great features and a design that lends itself to the story. Reflector ink makes sure you are visible on the mountain or on the couch, either way, you are sure to be comfortable in this memorable piece.
