LOKSAK aLOKSAK waterproof pouch 3 pcs 8.6x16.2cm

The manufacturer guarantees waterproofness up to a depth of 60 m for 200 opening-closing cycles. Smaller water depth, or in the case of moisture - snow - dust, according to experience, it protects without problems even after several (ten) thousand uses. For each closure, the sealing edge must be smoothed twice, then the bag must be compressed by hand (compressing the air inside) to check the pressure retention. If the air was squeezed out before closing (e.g. when inserting a map), then a short wait is required to check that it is leak-free.
