If you are looking to put your rack on a diet, look for the extremely light weight 27g Moses biner from Mammut.
- All Mountain Access
The Mammut Express Set Moses Quickdraw includes two wire gate carabiners and an ultralight Dyneema sling for versatile pro on burly routes.
Weighing in at just 27 grams, it is one of the lightest carabiners on the market. The Mammut? Moses wiregate is the ideal companion for mountaineering or whenever weight matters.
Mammut stepped up to the needs of weight-obsessed climbers by creating the 27g Moses Wire Gate Carabiner. This ultralight 'biner should be on your rack whether you cast off for a long single-push alpine climb or 20 pitches of rock. The wire gate on the Moses Carabiner doesn't freeze shut in cold weather and eliminates gate flutter to reduce the chance that you'll load an open-gate 'biner at the end of a 40-footer. Trad, ice, or alpine--the Mammut Moses Wire Gate Carabiner lightens your rack.
