MASH X BOREAS 2017 Jan 11, 2017 Categories: MASH, San Francisco, STORE 0 Comment 2017 brings new collaborations with local bag maker Boreas. We have 3 new designs, including updated features on the 50L race day bag. This bag has proven itself over the past four years, quickly becoming the go to travel bag for the team. This season we added a roll-out changing matte to the shape. The coated nylon matte is connected inside a sealed pouch inside the bag, and offers a clean dry place for your feet as you change clothes. The race day bag, and 2 additional designs are available in our shop, and at on our site today.
