The Fjallraven Keb Three Seasons sleeping bag comes with some handy extras which Kirsty Pallas recommends – but also a heftier price tag.

Fjallraven isn’t a brand I had associated with sleeping bags, but the Fjallraven Keb Three Seasons W is a lovely and toasty 3 season option. It’s a mummy shaped bag, but slightly altered for a female frame, so has narrower shoulders, wider at the hips, and is overall shorter than the regular model.

Kirsty Pallas recommends

The women’s Keb is a nice, warm 3 season option, but comes with more weight and bulk, and also a higher price tag.
Pros
  • vertical baffles on shoulders
  • poppers to back up zips

  • weight
  • price

As a women’s bag, it is also rated 3 degrees warmer, due to women usually sleeping a bit cooler. This does however increase the weight and bulk, with this bag coming in at 150g more than the regular model.

The anti-snag zipper works smoothly, and there’s poppers along the inside of the zip which can either be used in case of zip failure, or for ventilation when you want a bit of air, but not a fully open bag. These poppers also feature on the draft collar, so you can get it snugged right around your neck, or a bit more open for some air. Both the hood and the draft collar have toggles for adjusting, and can be used with one hand for both tightening and loosening.

There’s also a handy little pocket by the zipper which would fit a phone or headtorch, nice things to have to hand. The baffles are mostly horizontal across the bag, but there is a short section of vertical baffles across the shoulders. This helps keep the down more central and stops it falling away down the sides through use.

There’s also a mix of fabrics on the bag, with most of it in 20D, but the hood and footbox in 30D with a water resistant finish, which helps protect the down on those condensation heavy mornings.

The women’s Keb is a nice, warm 3 season option, but comes with more weight and bulk, and also a higher price tag.

Testing Conditions

These bags were tested through a warm and dry spring in the Highlands. Kirsty is five foot tall and sleeps fairly warm. All weights are from her own scales. This review was first published in the September 2025 issue of The Great Outdoors.
