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 genuine comfort while resting, thanks to a mummy cut that is roomier and less restrictive than technical alpine models.

Real technical performance

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

The combination of 650FP European duck down with a hydrophobic treatment and L.O.F.T.™ construction allows it to maintain loft stably, improving thermal efficiency and reducing heat loss during the night.
