Proof — the technical apparel brand based in the Bay Area — did it right with this sleek and minimalistic jacket cut from a lightweight fabric known as graphene. "It's world-renowned for its off-the-charts strength-to-weight ratio," notes the brand. "Higher even than steel." 

The ultra-lightweight fabric is filled with down insulation, which not only keeps you warm but packs down small when on the move. It's finished off with an interior chest pocket for your EDC essentials and YKK reverse coil zippers.

If you like what you see, make sure to use the code "graphene" right here for 40% off your jacket. Discount applies to both colorways.
