Zip it up and take it with you in the Poler Dry Bag. The possibilities are limitless but the idea is that the Dry Bag can be zipped into your Poler High & Dry 40 L and 20 L backpack to store your wet surf gear, towels, toiletries or whatever else got down and dirty. If you're not a surfer or a camper but you workout, the Poler Dry Bag is essential to put your sweaty gym clothes in. Keep your clean goodies fresh and the rest in the Poler Dry Bag because c'mon, you gotta' keep it separated.
