If you're not warm enough, the human race might die out. Or at the very least, you'll, ummmm, get goose bumps. Lucky for all of us, the Arc'teryx Men's Phase SV CZ Bottom exists. The heaviest hitter in the Phase family, these long undies should keep you warm during your chosen cold-weather activity. The majority of this baselayer is made from Phasic SV, a warm and wicking material. Behind-the-knee panels are crafted from Phasic AR, which helps hot air escape so you don't overheat when you're boot-stepping straight up the mountain. A gusseted crotch and full-zip fly mean that come December, you can kick and scream your way through playoff games in Green Bay or Buffalo, and never leave your 50-yard line, field level seat, if so inclined. Flatlock seams minimize chafing during your mid-winter runs. Encapsulated silver ions reduce odor build-up on the fabric, just in case you can't find a washing machine for a few weeks.
