Mountain Hardwear Absolute Zero Suit

Best For: The Mountain Hardwear Absolute Zero Suit is best for alpinists summiting high altitude peaks.

When you’re headed to the top of the world’s highest peaks, you need serious outerwear to handle the most severe conditions you’ll encounter.

The Mountain Hardwear Absolute Zero Suit is insulated with warm, lightweight 800-fill waterproof goose down and constructed with fully welded, watertight baffles to keep that down—and climbers—dry and warm.

The suit's shell is made from BodyAirShield nylon ripstop fabric with reinforced panels at the elbows, knees, seat, and hem for durability. Mountain Hardwear’s Dry.Q Core treatment adds waterproof-breathability.

Designed for high altitude climbing with the input of top alpinists, the Absolute Zero Suit includes a collar that’s compatible with oxygen masks; an adjustable internal suspender system to hold your suit in place; and a watertight six-slider rainbow rear-zip (for when nature calls).

All of the Absolute Zero Suit’s features are designed to work with a climber’s specific high-altitude needs, including two large alpine pockets at the chest that work with a harness and pack, plus a pocket at the thigh; two interior pockets that let you store your water bottles close to your body; a fixed, fully insulated hood that’s low profile and can be adjusted with one hand; and internal cuffs to keep out drafts.

A pre-cinched waist gives users a closer fit. The suit weighs 3 pounds 15 ounces (1.78 kg).
