Keep moisture-sensitive items safe with the water-thwarting Pack-It Dry Packing Cube. Made of Tpu polyester and welded seams, it s waterproof in every situation shy of a full-on dunking, so it can safeguard headphones and a book—or keep bottled toiletries from seeping into your clothes. Heavy-duty lash points and snap-closure straps let you piggy-back it to other bags and backpacks to keep valuables dry yet accessible on boats, beaches, and rainy hikes.
