The inside of a tent or snow cave on a cold-weather expedition can be a surprisingly humid place. Winterlite -42 integrates a hydrophobic, windproof, highly vapor-permeable shell Texped Membrane with high-loft, RDS-certified down and a sculpted hood to combat insidious moisture and extreme temperatures. Expedition-ready and amazingly compact, light and efficient. Please be aware, that the cut is really roomy to fit together with additional liner or equipment.

That's why we only give a temperature recommendation for our thick expedition sleeping bags that has been tested in practice. Factors such as the physical condition, the mattress, the tent and the current weather play a huge role here, which cannot be represented by test results. -42° C can be regarded as an extreme value.
