The Mountain Hardwear Chugach pant is no more (except on outlets, of course): long live the Compressor! Like the Chugach, it has a companion jacket. A synthetic combo like this is essential backcountry gear for when 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. One difference from the Chugach is the ripstop nylon shell, which should be a bit tougher. The size is also a bit larger and longer, and the insulation is now MH’s Thermic Micro instead of the old Polarguard 3D.
They insulate well without being too constricting, pack down small and are great for extended belay station duty. The only improvement they could make is to have the pee zipper zip open from the bottom to be more harness friendly.
