Light and dry.

When your pack is tipping the scale 32 pounds plus ten candy bars, two cake pastries, and a bottle of wine, you can afford to shave off a little weight—let the SealLine BlockerLite Dry Sack assist you in this endeavor. Crafted with a super lightweight yet rugged nylon material, the BlockerLite has a silicone and polyurethane coating that makes the sack totally waterproof while the welded-seam construction, block shape, and double-sealed roll top puts the icing on those two cake pastries you insisted on hauling around.

  • Familiarity: I've used it several times

The 2.5L makes for a nice ditty bag. I use it as an emergency/first aid kit for day trips into the backcountry. Nice carrying capacity and the rectangular profile fits well in the pack.
