Petzl Adjama vs Black Diamond Momentum Harness
Which should you buy? Our verdict on both, pulled from our full The Best Climbing Harnesses: 4 Compared (and One to Skip) comparison.
The Adjama carries a full trad rack on five gear loops and adjusts at the legs for winter layers, which makes it the most broadly useful harness here. The Momentum gives up one gear loop and some padding refinement but keeps the adjustable legs and adds a haul loop for a lot less money.
