The OMM Mountain Raid 233 WP is a fully waterproof, ultralight and extremely warm synthetic sleeping bag , developed for cold, wet and exposed environments where a traditional sleeping bag shell is not enough. It is OMM's most protective sleeping system , created for Mountain Marathons, mountain running, fastpacking and minimalist bivouac nights where every gram counts – but where you can't compromise on warmth or weather protection.

WP stands for Waterproof , and that’s exactly what this sleeping bag is. The outer fabric is made from PointZero® H₂O , the same waterproof and breathable material used in OMM’s Halo garments. The shell has a waterproof rating of around 10,000mm and good breathability , meaning the sleeping bag can handle condensation, wet ground and light rainfall – perfect for use with a tarp, bivy or in emergencies without any protection at all.

Inside , PrimaLoft® Cross-Core Gold , OMM's most advanced synthetic insulation, is used. The insulation is zoned for maximum efficiency:

133 g/m² on the top side

100 g/m² on the underside

This construction, named 233 , focuses warmth where it matters most, while keeping the weight extremely low. Like other Raid models, PrimaLoft® Cross-Core Gold insulates even when wet and dries quickly.

To minimize heat loss and weight, the Mountain Raid 233 WP features a half-length YKK zipper , a snug mummy fit , adjustable hood , and shaped foot box . The combination reduces dead air and retains warmth even on really cold nights.

Despite the waterproof shell and high level of insulation, the Mountain Raid 233 WP only weighs around 640 grams , making it unique in its class – a waterproof sleeping bag that is actually light enough for competition and fast-paced adventures.
