Outlet Cool Light Long Sleeve Tee Baselayer – Long Sleeves

Jump to: Our Verdict / Features / Specifications

Breathable, featherlight, and built for movement in the height of summer.

Montbell says:

Made of the lightest knit t-shirt fabric in Montbell’s lineup and designed for intense workouts, high-output days on the trail, or activities during the hottest summer months. Knitted extremely thin to prevent heat build-up while providing an exceptionally cool feel. Anti-bacterial properties help control odour-causing bacteria.

Our Verdict

The Montbell Cool Light Long Sleeve Tee delivers excellent airflow and comfort during warm-weather exertion. At just 103g (Medium), it’s one of the lightest long sleeves I’ve come across, yet it manages to feel robust enough for regular use if treated with reasonable care.

The Wickron COOL fabric is soft against the skin, dries rapidly, and doesn’t cling when working hard. Fit is athletic but not restrictive, with well-judged stretch and a cut that layers cleanly under a windshirt. Flat seams minimise abrasion, and the spiral cuffs sit neatly on the wrist without sagging or bunching.

In high-output scenarios, such as fast hiking or trail running, breathability really comes into its own. The fabric vents well even under a pack, and the odour control holds up across multi-day use.
