The OMM Mountain Raid 233 is OMM's warmest sleeping bag and is designed for cold conditions, winter and autumn adventures and Mountain Marathons where both light weight and reliable warmth are essential. With advanced synthetic insulation and thoughtful construction, this is the sleeping bag for those who want to sleep warm even when the weather is wet, cold and unpredictable.

The sleeping bag is insulated with PrimaLoft® Cross-Core Gold , OMM's highest-rated synthetic insulation, which offers very high warmth-to-weight performance and works even when wet. The insulation is strategically zoned for maximum efficiency:

133 g/m² on the top side (where the heat demand is greatest)

100 g/m² on the underside (where insulation is otherwise compressed)

It is this distribution that gives the name 233 and makes it possible to keep the weight extremely low without compromising on warmth.

The shell is OMM's PointZero® nylon , a very lightweight and windproof material with a DWR treatment that resists moisture and condensation. Together with the synthetic insulation, this makes the Mountain Raid 233 a reliable choice in humid and changing mountain conditions , where down often loses its performance.

To minimize heat loss and weight, the sleeping bag has a half-length zipper , which reduces cold zones and unnecessary material. The mummy-shaped fit , combined with an adjustable hood and shaped foot box , minimizes dead air and helps keep warmth where it's needed most.

Despite its high level of insulation, the Mountain Raid 233 only weighs around 540 grams , making it one of the warmest sleeping bags in its weight class and an obvious choice for fast, light adventures in cooler climates .
