Surf Sack For Triathletes

The world's 1st, compact, multi purpose, lightweight, and adjustable clothes changing invention that transforms into a 100% waterproof backpack.

This product is great for triathletes who need to change in the transition area.

Atheltes can carry all their gear in the Surf Sak, carrying it as a bag or a back back.

Then it opens up and they can actually change inside of it from their wet bathing suit and into running/cycling attire.
