Men's Nike ACG Wildsee Base Layer Tee - UV-Resistant Moisture-Wicking Foundation

The Women's Nike ACG Wildsee Base Layer Tee uses soft, stretchy fabric with UV resistance and sweat-wicking Dri-FIT technology. Built as part of the ACG nesting system, this snug base layer works on its own or underneath mid and outer layers when conditions require.

Dri-FIT Sweat-Wicking Technology

Nike Dri-FIT technology moves sweat away from skin for quicker evaporation during activity. The moisture management keeps you dry and comfortable whether worn solo on warm days or as foundation beneath additional layers. This base layer performance works across varied output levels.

UV Resistance with Soft Stretch Fabric

UV-resistant fabric provides sun protection during exposed mountain or trail running. The soft, stretchy construction maintains comfortable feel against skin whilst allowing natural movement. This combination handles sunny conditions without sacrificing mobility or comfort.

ACG Nesting System

Designed as part of the ACG layering system, allowing adjustment to climate and activity level. Wear the snug base layer alone during warm conditions, add a mid-layer when temperatures drop, or complete with outer layer when weather demands full protection. This nesting approach adapts to changing mountain conditions without carrying excessive gear.

Is the ACG Wildsee Base Layer Right for You?

Built for mountain athletes needing adaptable base layers across changing conditions. The UV resistance handles sun exposure during alpine running whilst Dri-FIT technology manages sweat when you're working hard. Soft, stretchy fabric stays comfortable against skin whether worn alone on warm ascents or as foundation when weather turns. The ACG nesting system design means this base layer integrates with mid and outer layers rather than fighting them—essential when starting cool, warming up mid-run, then cooling down at elevation. If you run or hike in mountains where conditions change with elevation or time of day, the adaptable layering approach handles transitions without carrying multiple complete outfits.
