Elevate your performance under the sun with the Outdoor Research ActiveIce Spectrum Sun Long Sleeve T-shirt. Engineered for the modern adventurer, this technical top delivers an unparalleled cooling sensation precisely when you need it most, allowing you to push your limits in warm and exposed environments. It’s more than just a piece of clothing; it´s a critical tool for thermoregulation and sun protection, designed to keep you comfortable and focused from the trailhead to the summit and back. The revolutionary ActiveIce™ technology is engineered with self-cooling properties that actively lower your skin temperature as moisture and sweat build up, providing a refreshing sensation that keeps you comfortable during intense efforts.
Made for daily sun exposure and high-output movement, this technical tee offers the perfect balance of coverage and cooling.
ActiveIce™ fabric cools as you sweat, while UPF 50+ shields you from harsh UV rays.
With a chafe-free construction and dynamic reach design, it supports full mobility without restriction.
Side hem slits and thumb holes boost versatility in a breathable, quick-drying layer that doesn´t weigh you down.
Whether you´re hiking, trail running, or paddling under a blazing sun, this long sleeve keeps performance high and distractions low​.
Don´t let the sun dictate your schedule. The integrated UPF 50+ sun protection provides a superior defense against harmful UVA and UVB radiation, safeguarding your skin during prolonged exposure and allowing you to focus on your adventure, not your sunburn. Meticulously designed for movement, the shirt features a chafe-free, flat-seam construction that eliminates irritation points, even when worn under a pack. The articulated ´Dynamic Reach´ patterning ensures the hem stays put and your arms have complete, unrestricted freedom of movement for climbing, casting, or reaching for that next hold.
Thoughtful details enhance its functionality across various disciplines. Integrated thumb holes keep your sleeves securely in place and offer added sun protection for the back of your hands. Side hem slits improve airflow and provide a cleaner fit when worn with a climbing harness or a backpack hip belt. The lightweight, highly breathable, and quick-drying synthetic fabric excels at wicking moisture away from your body, preventing the clammy feeling associated with heavy exertion. It remains light and airy, ensuring you´re never weighed down on the trail or on the water. This shirt is your go-to gear for alpine ascents, desert treks, long days on the water, or any activity where sun and heat are a factor.
