Mountain Hardwear Men's Airmesh Long Sleeve Hoody

Mountain Hardwear Airmesh Long Sleeve Hoody

A uniquely engineered active base layer hoody built on the highest warmth-to-weight ratio fabric in Mountain Hardwear's lineup. The Airmesh's hollow core yarn construction absorbs sweat quickly, supports insulation properties, and reverses for two distinct levels of warmth and airflow in a 6.3-ounce packable layer that earns its place from the skin track to the summit and everywhere in between.

Why We Carry It
It's the base layer hoody we recommend for ski tourers, ultralight backpackers, and mountain runners who want a single layer that genuinely manages temperature and moisture across wildly different effort levels without carrying two separate pieces.

Highlights

• Hollow core yarn brushed mesh construction Tube-like fibers that absorb sweat quickly and efficiently while supporting insulation and heat-shielding properties for temperature regulation across changing effort levels. A genuinely different base layer fabric rather than standard polyester in a different weave pattern.
• Reversible for two warmth levels Worn normally for maximum warmth and moisture management, reversed with the backer facing out for 28% more airflow and active cooling on high-output efforts. One layer that adapts to significantly different conditions without stopping to change.
• Highest warmth-to-weight ratio in the Mountain Hardwear lineup A 115 g/m² fabric weight that delivers more warmth per ounce than anything else in the collection for a base layer that punches well above its 6.3-ounce weight on cold days and at elevation.
• Moisture-wicking stretch neck section A soft knit fabric construction at the neck for comfortable head movement and active moisture management at one of the body's highest sweat areas during sustained effort.
• Anti-odor finish Keeps the hoody wearable across multiple days in the field without washing for ultralight backpackers, ski tourers, and expedition athletes who can't do laundry on the go.
• Fitted three-piece hood A close-fitting, structured hood for extra protection at the head and neck that layers cleanly under a helmet or shell without bunching or shifting during active use.
• Thumbholes in soft knit fabric Keeps sleeves in place under gloves and outerwear during high-output activity without the irritation of a harder fabric thumbhole construction.
• Secure zip pocket at front left A lightweight, minimal storage option for a key, card, or small essential without adding meaningful weight or bulk to an ultralight base layer.
• 6.3-ounce weight at medium Genuinely packable base layer weight that disappears in a kit without being noticed until it's needed. A legitimate ultralight option that doesn't ask you to sacrifice warmth to hit the number.

Best For

Ski tourers, ultralight backpackers, mountain runners, and expedition athletes who want an engineered active base layer hoody with the highest warmth-to-weight ratio available, reversible ventilation options, and genuine moisture management for variable effort levels across a full day in the mountains.
