If you've ever used the elemental layer in cold weather, you know the difference it makes on a ridge in winter. But here's a question that comes up more than you'd think: "Do you need an elemental layer in summer?"
The short answer is yes, and here's why.
A surprising 76% of hikers have experienced post-sweat chills even in summer. If you've ever felt that unpleasant cold creep the moment you stop moving on a trail, you already know what this means. And yet some still think the elemental layer is for winter only. The reality? Just as many, if not more, of our users wear it in summer for hiking, trail running, or whitewater kayaking than skiers do in winter.
The mountain sweats you more than you think
A 60kg (132 lb) hiker moving for 6 to 7 hours produces roughly 2 liters (1/2 gallon) of sweat. That moisture saturates your layers and stays there. Even quick-dry fabrics take about 70 minutes to dry completely. That's over an hour of wet fabric against your skin while you keep moving, gaining elevation, and entering colder air.
Summer mountains are not summer weather
Temperature drops 6°C (11°F) for every 1,000m (3,300 ft) of elevation gained. A comfortable 30°C (86°F) day at the trailhead becomes 12°C (54°F) at a 3,000m (9,900 ft) summit. Wind drops perceived temperature by roughly 1°C (1.8°F) per 1 m/s, so at 12 m/s (27 mph), that summit feels like 0°C (32°F). Factor in temperatures after sunset, and anyone staying overnight or running through the night knows how quickly conditions can turn.
Wet fabric actively works against you
Water conducts heat approximately 25 times more efficiently than air. Sweat isn't the only threat either, as a sudden rain can soak you just as fast. A wet layer against your skin pulls heat away rapidly, draining your energy when you need it most to go the distance.

What the Elemental layer actually does
The Elemental layer doesn't wick sweat. That's the base layer's job. What it does is stay dry itself, allowing sweat to pass through to the base layer above while maintaining a dry surface against your skin at all times. It keeps you moving through changing elevation, shifting weather, cold mornings, and long nights, with the confidence that you'll make it home safe.
Keeping your skin dry keeps you safe.
That's why we wear Elemental Layer in summer.
