For ggg only: OMM Core Liner Orange Std

Introducing the Core series, featuring the innovative new material PRIMALOFT® ACTIVE.
The OMM's intended environment of intense activity in cold, wet conditions is highly effective in various Japanese mountains during autumn and winter. This revolutionary series is designed to maximize your performance.

The CORE LINER is an inner sleeping bag that raises the lower limit of your sleeping bag's temperature rating.
Weighing 175g and with a TOG value of 0.7 for standalone use, it's not an astonishing figure on its own. However, its key feature is its ability to significantly expand the usable temperature range when used inside an existing sleeping bag to improve airtightness.

While the exact temperature increase when used as an inner sleeping bag isn't officially published, you can expect a noticeable warmth increase of approximately 5 to 8 degrees Celsius based on experience.
Its moisture and water-resistant material also functions as insurance for down sleeping bags, and its hood makes it an excellent match for quilt-style sleeping bags.
