Featuring welded seams and waterproof 100% recycled TPU polyester, the Pack-It Dry Packing Cube shields contents against daylong rain or an errant beverage container. It's equally good at isolating wet, messy gear: Sandy travel towels, snow-soaked gloves, and leak-prone bottles can travel inside to keep the rest of your stuff dry and clean. Heavy-duty lash points let you secure it to a backpack or duffel where it delivers waterproof protection in all soggy situations except fully underwater dunkings.
