Women OMM Womens Core Jacket

Jump to: Our Verdict / Features / Specifications

UOG TOP PICK: The Core Jacket is designed to provide active insulation. It adds warmth but is highly breathable and focused on wicking moisture and regulating body temperature when exercising, a Top Pick.

OMM says

A new concept in active insulation, the OMM Core Range is made entirely from PRIMALOFT NEXT ultra-light insulating fabric. Built from a synthetic plume woven through a knitted mesh, Core offers the warmth of a fleece but less-than half the weight. Paired with a shell, the Core is an incredibly effective insulator; but, thanks to near-total air permeability, the lightest breeze can take away that heat. This allows you to keep your Core layer on even when you have warmed up and you can thermoregulate by removing/unzipping your low bulk shell (eg. Sonic windproof at 49g). A true valley to summit piece. Core works wet or dry with incredible wicking properties to ensure you won’t stay wet for long.

The Core Jacket uses the 125g PRIMALOFT® NEXT Insulating Fabric Technology. Go even lighter and try 75g PRIMALOFT® NEXT fabric used in the Core Vest & Hoodie.

Our Verdict

OMM’s Womens Core Jacket uses Primaloft’s Next insulating fabric which is designed to add a layer of warmth for cold weather exercise. The focus of the material is breathability, moisture management and regulating your body temperature as much as possible when running or hiking. It does a great job in this way and is a great piece of kit for colder conditions. The fabric provides zero protection from the wind so you will still need a soft- or windshell over it if there’s a cold wind.

There are two small pockets for keeping essentials in (I couldn’t really fit my hands in them), a good high collar and all the zip pulls are easy to grab even with gloves on. With the fabric looking the way it does, there is a question mark over durability but thankfully this has not been an issue in use. Worn as a mid layer and outer layer with a running pack the top still locks in great condition.
