These are the companion pants to the Chugach jacket. They are essential backcountry gear for applications where down pants would be overkill or wet weather is a factor.
Full side zips make it easy to slip on and off without removing boots. The reinforced butt and knees make it a tough performer that will last for more than one expedition.
They insulate well without being too constricting, and are great for extended belay station duty. Plus, the price is reasonable and being Mountain Hardwear they’ll outlast your bum.
