With airlines cracking down on baggage weight, your lightest option for a checked bag is a big roomy duffel bag. But flight delays and overburdened baggage-handling systems mean your bag could be sitting on the tarmac for an extended period, which would leave a typical duffel soaked through in bad weather. Not so with

Seal Line's waterproof Storm Sacks

. Made of featherweight nylon with a PVC-free waterproof coating, the bags have roll-top closures and sewn and taped seams that make them virtually watertight. Available in blue or orange in seven sizes from 165- to 3,661 cubic inches.

Storm Sacks are $11 to $35, depending on size at www.seallinegear.com; 800-531-9531.
