the OMM Core+ Hoodie

the OMM Core+ Hoodie – Warmer & More Robust Active Insulation in PrimaLoft® Active

See our entire range from the OMM here!

The OMM Core+ Hoodie is a warmer, more durable and still extremely breathable midlayer , developed for cold, windy and demanding conditions where you move at high intensity. It is part of OMM's groundbreaking Core series , which is based entirely on PrimaLoft® Active , an insulation material that combines fleece-like warmth with less than half the weight and significantly better moisture and temperature regulation.

The Core+ variant uses the heavier 125 g/m² version of PrimaLoft® Active , making it noticeably warmer and more robust than the Core Hoodie (75 g/m²), but without losing its characteristic almost total air permeability . The insulation consists of synthetic plumes woven directly through an open mesh material , creating large air pockets that effectively trap body heat, while quickly venting excess heat away when the pace increases.

This makes the Core+ Hoodie a true “valley-to-summit” garment . Combined with a thin shell, such as OMM Sonic Windproof, it acts as a surprisingly warm insulation system with extreme warmth-to-weight performance. If you get too hot, you can easily adjust the temperature by opening or removing the shell – the midlayer itself can stay in place even during hard physical exertion.

The garment works equally well wet or dry . PrimaLoft® Active insulates even when wet and dries very quickly , making the Core+ Hoodie ideal for long days in variable mountain weather. The soft, rolled hood acts as both a hood and a warming collar , providing extra protection without interfering with movement patterns.

Weighing in at around 185 grams, the Core+ Hoodie offers an unusually high level of warmth in a very lightweight and packable format , making it an obvious choice for trail running, fastpacking, alpine adventures and ultra races where traditional insulation garments become too constricting.
