The midlayer that keeps pace

As intensity rises, excess heat quickly becomes a problem. Sweat, overheating, discomfort. In mountaineering, climbing or ski touring, a midlayer needs to regulate your temperature, not let heat build up.

This one is built for sustained effort. Its grid-structured fabric retains the warmth you need while letting excess heat escape. Stretchy and close-fitting, it moves with you. The hood fits under a helmet, and the high-set pockets remain accessible above a harness.

Because when you’re pushing hard, performance depends on keeping your temperature under control.

In summary This content is written by AI

Customers particularly appreciate its light weight, comfort and breathability: many wear it as a mid-layer for hiking, climbing or ski touring without adding bulk. It provides just the right amount of warmth, including around 0°C when worn with a fleece layer, while wicking sweat effectively. Several highlight how little space it takes in a backpack and the practicality of its pockets; some call it perfect for demanding hikes. It has a close, sometimes small fit: size up for more room.

I've been using Cimalp products for years, especially when I was looking for a softshell for going out with my dog. Then I go hiking in the mountains. Recently, I tried this fleece as an under-jacket (Dynamic) for skiing. Fabulous! Warm and breathable. The hood can be worn under a helmet.

Tested in zero-degree weather in the morning, the jacket performed well, although a fleece layer is still necessary. As the temperature rose, the jacket proved breathable, and on the descent, the strong north wind effectively blocked it. Excellent product.

My usual size is M (I'm 175 cm and weigh 74 kg), but I chose the L and it's perfect! Excellent product, beautifully finished, lightweight yet warm enough for a second layer. Excellent, like all the items I've purchased so far from Cimalp!

Excellent mid-layer for mid-season. Can be worn under a waterproof jacket without restricting the sleeves. Size 1.65m, 58kg I approve.

Good, lightweight, warm, and breathable softshell. High pockets designed for harness use, but unfortunately, the jacket's zipper doesn't allow for bottom opening, which would have been very useful. This is the only drawback of this Ares jacket after two days of intensive use ski touring in winter conditions. The hood doesn't look very stylish when up, but that's a minor issue.
