Lightweight Crater Lake Long-Sleeve Crop Top delivers UPF 50 sun protection for warm-weather adventures

What Our Gearhead® Experts Are Saying:


"I reach for this top when I want sun protection without overheating. The fabric is super lightweight and breathable, and it dries quickly when you start sweating. I also like the cropped fit—it pairs perfectly with high-rise hiking tights or shorts and still gives you great coverage with the mock neck and thumbholes."


When sunny trails and warm weather call for long days outside, we pull on the Mountain Hardwear Crater Lake Long-Sleeve Crop Top. Lightweight and breathable, this sun-ready layer keeps us comfortable whether we’re hiking dusty switchbacks, paddling along quiet shorelines, or setting up camp beneath a clear sky. The cropped design pairs naturally with high-rise bottoms, giving us a modern silhouette that still feels functional on active days outdoors.


Built for movement in the heat, the performance fabric wicks moisture away from our skin and dries quickly when the pace picks up. Stretch from the elastane blend allows us to move freely on scrambles, climbs, and paddle strokes, while the UPF 50 rating shields us from harsh sun exposure. A mock neck and low-profile thumbholes extend coverage across the neck and hands, helping us stay protected during long hours in bright alpine or desert conditions.
