Electronics and paper are no match for the elements--unless they're guarded by the material of Aloksak Storage Bag from Loksak. Made with a multi-patented design, this set of 4 bags will keep your valuable items like maps and phones dry and safe so you can push farther into the backcountry. When you do need to look at your phone, most screens are usable through the material for ultimate utility in unpredictable alpine weather. Even though the bags will need to be replaced after extended use, they'll protect your belongings as long as they possibly can.
