TREW Pack Jack

Size Guide

Produced in collaboration with Trew Gear, we're stoked to reveal the Trew pack jack in our Trew X Sensi Funky Fern print! Pair with any of our Funky Fern bikinis for a dream beach combo!

The Pack Jack is made of a mighty material! This particular micro ripstop is also  light, and buttery-smooth. A breathable, PU coating and DWR finish makes our Pack Jack wind-proof and water-resistant, while simultaneously allowing for your body’s moisture accumulation to escape.

Business in the jacket, party in the fanny. Not only is our Pack Jack an incredible looking, lightweight, first line of defense against the elements, it also packs into its built-in fanny pack!!
