The XO 6.2 Backpack from Helixot is completely watertight. Instead of zippers it uses a screw cap system as a quick and simple way to keep constant pressure on the seal. Its ergonomic design hugs your back and prevents it from shifting. Its smooth surface enables it to glide past obstacles without getting caught. The dorsal padding prevents items within the bag to injure the user. So whether you're surfing, canoeing, hiking, skiing, or just camping you can rest assured that your belongings are safe and dry.
