A lightweight sleep system with great next-to-skin comfort and breathability. With the 250g/m2 weight PrimaLoft® ACTIVE as the liner fabric, the Mountain Core 250 offers an open fleece feel but with the added benefit of an unrivalled warmth-to-weight ratio for any fabric.

Externally, the PointZero fabric gives great windproofing with a DWR (Durable Water Repellancy) for when your pack takes a dunking en route to camp. The total package retains the packability you’d expect from OMM.

PrimaLoft® ACTIVE blurs the line between wadding insulation and fabric; PrimaLoft® ACTIVE loosely weaves PrimaLoft®’s industry-leading insulating fibres through a fine polyester mesh. The resultant structure is warmer and less than half the weight of a conventional fleece product – Down like performance when dry whilst also still performing when wet.
