"The Kelvin Lite Pants are the only way I've found to combat tons of glassing in brutally cold weather, like a November sheep hunt in Alberta. You can layer your upper body, but if your whole body doesn't stay warm, you’ve got to move on. Being able to force yourself to hang tight until you can pick apart the whole mountain can make the difference between seeing a ram stand from his bed or as he steps out from cover and completely missing him. I’ll use the full side zips to throw on overtop of whatever pants I’m wearing and instantly gain the ability to be behind for the glass for hours. They’re not needed for every single hunting application, but for any mountain hunts with periods of inactivity from mid-October on, they’re a godsend."
