Keep moisture-sensitive items safe with this water-thwarting packing cube. Made of 100 percent recycled 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 and located on boats, beaches, and rainy hikes.
