BEST FOR: Four-season adventures.
THE TEST: First, be aware that actual bacon is sold separately. What you do get is an impressively versatile and technical 28-liter pack; there are retractable tool loops for ice axes or trekking poles, and the side compression system can even carry skis. Of course, we found it performs just as well on mellower excursions. The hipbelt is more substantial than the REI pack’s but is removable. The only odd feature: when you cinch the hipbelt, the mesh pockets are virtually impossible to access.
THE VERDICT: Goes across continents as well as it goes up mountains. 1.4 lbs.
HAULING COMFORT: 3
