Tram is the full-featured option for serious skiers willing to ditch the wheels to save some dough and some weight. Load up the main compartment with skis, poles, boots, and outerwear, then stash travel papers and other essential items in the exterior zippered pocket. 360-degree padding keeps hardgoods protected, while the removable padded shoulder strap and end handle make for easy transportation. At an impressive 3.7 pounds (1.7kg), even when you're packing a full kit, you won't rack up extra baggage fees. Plus, it packs down tight for easy storage when not in use.
