Gear Review: Black Diamond Infinity 50 Backpack
Black Diamond Infinity 50
$210, 50L/3,050 c.i., 3 lbs. 14 oz. (men’s medium)
A lot of packs feel good when you first put them on; only a few are still your friend at the end of a long day. I carried this streamlined top-loader with upwards of 30 pounds on 16- to 18-mile days on the rugged Rees-Dart Track in New Zealand’s Southern Alps—and it stayed comfortable right up until I took it off every day. The key feature is BD’s ergoACTIV hipbelt that attaches to the pack via a simple ball joint: The hipbelt pivots with your hips, but the pack itself doesn’t, eliminating the side-to-side shifting with each step that can fatigue your back and rub your hips raw over the course of a full day.
