OMM Mountain Raid 233

OMM Mountain Raid 233

The Mountain Raid 233 uses the thicker PrimaLoft® Cross-Core Gold insulation to expand the temperature range of the bag, constructed from a combination of materials to ensure maximum performance. The windproof PointZero shell has a DWR treatment to aid water repellency and PrimaLoft® insulation, which performs even when wet. A half-length zip reduces cold spots and overall weight whilst a close-fitting, adjustable mummy style hood helps trap the maximum of heat. A tapered fit reduces dead air and the shaped footbox makes for a more comfortable sleep position. The Mountain Raid 233 is our warmest sleeping bag yet, perfect for lightweight adventures in the colder months or for the Mountain Marathon competitor looking for a better night’s sleep.

We take this high quality insulation and map different weights per panel to ensure the best usage of the fill. The base sheet is filled with PrimaLoft® Cross-Core Gold 100g/m2, whilst the top layer, above the sleeper, is 133gm/2 (giving us the 233g/m2 total in the name). Mapping the insulation in this way allows us to achieve such a low pack weight, there is no point placing excess wadding (and therefore weight) beneath the sleeper, as the weight of their body will compress it and reduce its ability to trap air and insulate. Instead, we focus the warmth on the top sheet and leave it up to you to decide what mat to use to insulate you from the ground.
