Our View - OMM Core Fleece Jacket Men: The OMM Core Jakcet is an active insulation concept, made entirely from PRIMALOFT ACTIVE insulating fabric, the material is a synthetic plume woven through a knitted mesh. The OMM Core Hoodie offers all the warmth of a fleece but with less-than half the weight. Pair the OMM Core Jacket with an outer shell and it provides incredible insulation but, thanks to its near-total air permeability, an excessive heat build-up easily dissipates. The Core Jacket uses the 125g thicker weight of OMM’s two Core fabrics and works wet or dry with incredible wicking & drying properties to ensure you won’t stay wet for long. This is an ideal piece for when you ascend quickly and build up a sweat but don’t want to catch a chill on the top or descent.
