OMM Core Tights | Ultra-Light Active Insulation Tights, Warm Even When Wet

From valley floor to mountain peak. An insulating layer designed for continuous movement.

For fastpackers and trail runners who want to keep moving even in the coldest weather, OMM Core Tights were developed.

Featuring PRIMALOFT® ACTIVE EVOLVE throughout, these tights offer a new generation of insulation material that combines fleece-like warmth with excellent breathability. They efficiently retain body heat while quickly dissipating excess heat and moisture generated during activity.

Despite their astonishingly light weight of just 130g, they maintain their insulating properties even when wet, making them ideal for a wide range of activities such as trail running and fastpacking in cold environments, and winter hikes. They can be used on their own or combined with shell pants for extreme cold conditions, offering high versatility.

The appeal of the Core series lies in its ability to keep you moving even while wearing it as an insulating layer. Unlike typical padded clothing, it minimizes stuffiness and heat buildup, providing continuous comfort from a cold morning start to high-altitude activities.

Especially for winter trail running and fastpacking, layering during activity is crucial, not just during breaks. These Core Tights bridge that gap. Lightweight and highly portable, they are a piece you'll want to keep in your backpack at all times.
