Active insulation in a pair of pants, it's that simple. These are the future for anyone in need of pants that work as hard as you do in colder conditions in the hills and mountains. Polartec Alpha Direct lining makes these soft, comfortable and warm but more importantly amazingly effective at regulating heat.
Ice and rock: conquer the mountain world with the Aenergy IN Hybrid Pants Men. The pants stand out with their very breathable Polartec® Alpha® direct insulation material combined with vapor-permeable, wind- and water-repellent Pertex® Quantum Air outer material on areas exposed to wind and cold.
The lining-free Polartec® Alpha® Direct offers heat retention without heat build-up. You are ready to face the mountain thanks to the climbing harness-compatible front pockets and the edge and crampon protection in robust Cordura® material.
Mammut's Aernergy IN Hybrid Pants will turn into a must for anyone heading outdoors in colder weather. The Polartec Alpha Direct insulation is really soft and comfortable but also gives you a decent level of warm. However, it works best when you're active as it breathes well and wicks amazingly so your temperature is regulated as you go. There are a couple of vents you can zip open or closed depending on the conditions too.
There are a couple of good sized pockets with secure zips, reinforced areas at the bottom of the legs to increase durability and plenty of other little features to increase comfort and improve the usability. These are without doubt my favourite pants for colder weather and they have had plenty of use and are still in perfect condition.
