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.
Using the thickest 250g/m2 weight PrimaLoft® ACTIVE fabric offers a warmer bag than the lighter Mountain Core 125 but with all the benefits of a comfortable sleep environment.
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.
Whilst not the warmest bag we offer, the benefit of using PrimaLoft® ACTIVE, instead of a traditional wadding insulation, we achieve a much more comfortable inner climate. With enhanced wicking and breathability, the open weave fleece fabric allows for much better airflow whilst the lofted plume still provides fantastic insulation values.
PointZero face fabric is windproof with good water resistance thanks to the DWR coating whilst PrimaLoft® retains its insulating properties even when wet, perfect for changeable conditions.
At OMM we always choose synthetic insulation over down to be sure that we can get warm even when everything is wet. PrimaLoft® make the best synthetic insulation. PrimaLoft® ACTIVE uses 64% post-consumer recycled material it is Bluesign and Oeke-Tex approved.
