The dots and dashes on this bottle just look like design-work at first glance but there's more to it than that. That "design" is Morse Code for 1917, the year SILCA was founded. Celebrate SILCA'S centennial year by carrying these unique bottles on your bike. The 22OZ Purist bottle will keep your drink cold and is easy to use while out on the road. The bottle was designed along with a pair of matching socks from DeFeet and a cap from Walz to compliment your Summer gear.
