the OMM Mountain Raid 233 WP

the OMM Mountain Raid 233 WP – waterproof sleeping bag for light adventures without compromise

The OMM Mountain Raid 233 WP is a weatherproof, lightweight and technically advanced sleeping bag developed for adventures where every gram of the pack must earn its place. By combining OMM's proven Mountain Raid 233 with the waterproof and breathable PointZero H₂O fabric, OMM has created an all-in-one sleeping system for mountains, fastpacking, mountain running and minimalist tours.

WP stands for Water Proof – and that's exactly what this sleeping bag is: a sleeping system that continues to perform even when the weather doesn't.

Waterproof shell with high breathability

The outer fabric is made of PointZero H₂O (nylon), a material commonly used in OMM's waterproof Halo garments. It provides:

10,000 mm water column (HH)

10,000 g/m² breathability

This effectively protects against moisture, condensation and light rain - perfect when using a bivy, tarp or minimalist shelter.

PrimaLoft® Cross-Core Gold - warmth even in wet conditions

The sleeping bag is insulated with PrimaLoft® Cross-Core Gold, a premium synthetic insulation that:

retains warmth even when wet

drys quickly

is lightweight and packable

OMM uses a panel-optimized insulation distribution:

100 g/m² underneath

133 g/m² on top of the body

This provides maximum warmth where it is needed, without unnecessary weight where the insulation is still compressed by the body weight.

Thoughtful design for maximum efficiency

Half-length YKK zipper – reduces weight and cold spots

Mummy-shaped fit – minimizes dead air

Adjustable hood – traps heat effectively

Shaped foot box – better comfort and warmth

Loose-fitting outer part & stitched inner part – optimized insulation

Temperature rating (ISO 23537)

Tested according to ISO standard with base layer, hat and insulating sleeping pad:

Comfort: +11 °C

Limit: +7 °C

Extreme: −5 °C

The waterproof membrane also contributes to increased actual warmth in the field.

Sustainable choice for modern adventures

90% recycled material (PCR)

PFC-free DWR treatment

One of OMM's most environmentally conscious sleeping systems to date
