What Our Gearhead(R) Experts Are Saying: "I reach for the AirMesh Hooded Top when I want warmth without overheating. The Octa mesh traps heat surprisingly well but still breathes during climbs or steep hikes. It's incredibly light and packs down small, so it's easy to keep in the pack for quick layering when temperatures drop."When the pace picks up and the air turns crisp, we layer up with the Mountain Hardwear AirMesh Hooded Top. Built with advanced Octa fiber technology, this ultralight midlayer delivers an impressive balance of warmth, breathability, and moisture management to keep us comfortable through high-output pursuits. The unique hollow-yarn mesh construction pulls moisture away from our skin and dries quickly while still trapping enough heat to keep us warm during chilly alpine starts. A fixed hood with a high neck provides added protection when the wind kicks up, while raglan sleeves and soft seams allow unrestricted movement on climbs, hikes, and backpacking trips. Integrated thumbholes keep sleeves in place and seal in warmth, making this featherweight hoodie a reliable companion for active adventures in cooler conditions.
