Sun Drift Cooling Long-Sleeve Shirt - Women's

What Our Gearhead® Experts Are Saying:

"On exposed hikes and hot travel days, this shirt has become my go-to. The cooling fabric really does feel instantly refreshing, and the HeiQ tech keeps it from picking up odors between washes. I love how the roll-up sleeves and mesh venting manage heat when the pace picks up. It’s lightweight, super functional, and genuinely comfortable for long days outside."

We reach for the Sun Drift Cooling Long-Sleeve Shirt when the day ahead promises bright sun and steady movement. Mountain Hardwear’s cooling fabric keeps us comfortable as temps climb, and the UPF 50 rating ensures we stay protected on exposed ridgelines, long desert approaches, and humid river crossings. The smooth, airy feel is made for warm travel days or full weekends spent chasing heat.

Built with HeiQ Cool technology for touch-cooling comfort and enhanced thermal control, this shirt goes beyond a simple sun layer. HeiQ Mint and odor-regenerating HeiQ technologies help maintain freshness through multi-day adventures, while mesh venting across the back and chest keeps air moving where we need it most. Adjustable roll-up sleeves and dual chest pockets add the practical function we expect for long hours outdoors.
