The CAMP USA Nano 22 is built for the climber who counts grams before leaving the trailhead. At 3. 4 by 2. 0 inches and 22 grams, it disappears on a gear loop without crowding out the next piece, the kind of margin that matters when a long alpine route demands a full rack plus a few extras. The updated nose and optimized rope-bearing surface address the wear points that show up after seasons of hard use on a lightweight trad carabiner that sees high cycle counts. What Our Gearhead(R) Experts Are Saying:"I use these mostly for racking cams on longer trad routes where weight adds up fast. At 0. 8 ounces each, a full rack stays noticeably lighter than standard biners, and the slim profile keeps gear loops from turning into a tangled mess."
