In short
Good for
- Spring-to-autumn camps in the UK where you want room to move and a bag that copes with a damp tent
Strengths
- Synthetic PrimaLoft fill: made to keep working when damp, and no special care needed for wet nights
- Roomy for a mummy bag: 80 cm across the shoulders and 55 cm at the feet
- Full-length two-way zip with anti-snag slider, draft collar and draft tube
Weaknesses
- Heavy at 1,550 g, over 1,300 g in the Regular size
- Fjallraven gives no packed size, and owners and shops say it packs large
- Comfort rating of 1 °C is no good for frost, and a few owners felt cold at 5 to 10 °C
- No independent hands-on test of this bag found, so the damp, comfort and durability scores are 'Not enough evidence'
- Regular fits users up to 185 cm only (a Long is sold)
