A very popular size for its flexibility, the Osprey Ultralite DrySack 12 Liter will carry a trip’s worth of clothing in a dry and compressed package if you pack right. The DrySack’s three turn closure will keep not only water out, but air out. Go ahead, pack it, squash it, roll it, and you’ve got a nicely compressed package of clothes ready to take up considerably less space in your luggage than you’ve any right to expect. This will also act as a liner in the Daylite packs for a fully waterproof carrying environment, particularly useful during the ski season when you’re counting on a dry layer when you get where you’re going, or want to be sure your camera or other gear is kept securely away from excess moisture. The snap to use clip style roll that blocks water is easy to use, and remarkably effective. While these make great pack organizers they’ll also shine in a kayak dry locker, ski bag or a boot bag, and make hauling damp gear back home at the end of a trip just that much easier. Just stuff it, squash it, roll it, clip it.. and drop it in your bag. A great dry sack which will see use all year around, from the ski season to the beach and back again. Rinse, air dry, pack, repeat, they’re light but tough, and ready to rock.
