Rab Ascent -12°C Sleeping Bag | 3-Season Down Trekking Sleeping Bag

Description

The Rab Ascent -12°C is a down sleeping bag designed to offer an optimal balance of warmth, comfort, and versatility in the mountains. Within the Rab range, the Ascent series is characterized by its focus on real comfort during rest, thanks to a wider, less restrictive mummy cut than technical alpine models.

Real Technical Performance

With a comfort temperature of -5°C and a limit of -12°C, this model is geared towards three-season trekking, mountain getaways, and moderate cold conditions. It is a very balanced option for those who need thermal protection without yet entering severe winter use.

The combination of 650FP European duck down with hydrophobic treatment and the L.O.F.T.™ construction allows for stable loft maintenance, improving thermal efficiency and reducing heat loss during the night.
