Go for the swimwear, rain jackets, and duffel bags, and stay for the lightweight Garden Island Top. This simple tank is a sustainable hemp and Tencel blend.

Purusha People

We’re loving Purusha People’s Daisies Square Bra Top! The Sky Blue design is sewn, dyed, and printed in Los Angeles. Another great look is the Tulip Gather Top in Sunshine Yellow. Both of these are constructed from GOTS-certified non-toxic dyes and are oh-so-cute and comfortable. Sustainable clothing brands for the win!

Ciele Athletics

Our workout go-to is the CRGTight Short 3.5” in Shadowsphinx from Ciele Athletics. Choose this short style for optimum compression, durability, and anti-chafe comfort. Pair these with any of the brand’s t-shirts, cropped tanks, or sports bras.
