This harness is absolutely ideal for what it is intended: Glacier Travel.
While not the absolute lightest harness on the market, it still does a mean job, coming in at a mere 230g. If wadded up carelessly, it is roughly the size of a coffee mug, and comes complete with belay and gear loops. This harness is much more comfortable than a traditional alpine bod harness, but still caters to the glacier-walker in all of us. Waist comes fully open and leg loops unbuckle allowing you to get this harness on over your crampons and all your puffy layers. Don't sacrifice pack space and weight by trying to use your sport harness for glacier--let the Culoir into your life, you will be well pleased.
