The Botl Sok from Java Sok is a neoprene for your 32oz Nalgene water bottle. It will also fit 48oz bottles, but obviously won’t cover as much of the bottle. It keeps the sweat at bay and helps keep your beverage cool.
Yep, this pseudo UCP pattern is the only camouflage they have, but maybe one day it will be cool, now that it’s just a bad memory. Otherwise, they’ve got a few other colors like Black and Hunter Green.
