It's another discontinued item, but you can get it now at a 20% price cut.

Designed to be worn underneath your other gear, the Rho LT Base Layer Hoodie is made to provide moisture-wicking and keep you warm. The built-in hood provides face coverage when up, and it has a zippered chest pocket to keep your smartphone safe. It's discontinued but available at a 30% discount.

Arc'teryx's Covert Fleece Hoodies is a basic item meant to be worn on just about any occasion. It's a good fall weather layer to keep you warm with moisture-wicking fiber and a full-coverage hood. It's now discontinued, but you can pick it up at a 30% discount to save a cool $60.

Built with hiking and climbing in mind, Arc'teryx's men's Proton Pants are made to stretch with a knit insulation that gives you extra warmth.

There are still plenty of sizes available for this Delta Jacket, though you'll have to be a fan of the very yellow Euphoria color. It's made of a light fleece that keeps you warm in cool weather and includes thumb holes on the sleeves to keep them in place. 

The Proton Insulated women's hoodie is 50% off, cutting its regular $350 price down to $175. The only catch? You're limited to medium size.

At 30% off, you'll save nearly $40 off the Rho Hoodie Base Layer Top in every size. The hood can cover your full face when it's up or be used as a neck warmer when it's down. The hoodie has some stretch to it while keeping a close fit through the chest, waist, and hips.

If you want to go without a hood, the Rho Lightweight Crew Neck top with long sleeves is an excellent base layer. It's available in several sizes at 30% off its usual price. Like the hooded version, it's made to stay close to the body while giving you a good amount of stretch with moisture-wicking and odor control.
