Summit Altimetro LT Crew delivers ultra-lightweight moisture control for alpine pursuits
What Our Gearhead® Experts Are Saying:
"This crew is one of the best base layers I’ve used for high-output alpine days. It’s light, super breathable, and dries faster than anything else I’ve tried. The DOTKNIT panels keep airflow moving, and I love how it layers under a vest or shell without bunching."
When every gram counts and performance is critical, we trust the Summit Altimetro LT Crew to keep us dry, light, and focused. Designed as part of The North Face’s elite Summit Series, this piece is built for race kits and fast alpine missions where sweat management matters.
Engineered with moisture-wicking DOTKNIT and FLASHDRY-PRO technologies, this crew top actively pulls moisture away from the body and regulates airflow through mapped mesh zones at the back and underarms. A slim fit ensures smooth layering under vests or hardshells, while thumbholes, reflective hits, and low-bulk seams round out this performance-forward design. When the pace is high and the temps are low, the Altimetro is our base layer of choice.
