This down sleeping bag is rectangular shaped for extra legroom and an all-around zipper means it can be paired with another sleeping bag or opened out as a large quilt.

And we only use down that carries the Responsible Down Standard (RDS).

30D PA Ripstop

Thanks to its extremely high weave density, highly water-repellent and breathable at the same time, the feather-light microfibre cover fabric protects the filling from clumping due to moisture - from the outside as well as the inside. The extremely fine, down-, fibre- and windproof nylon ripstop material impresses with its supple feel. Stability and abrasion resistance are achieved via the fine "ripstop" structure. It is produced according to the strict Bluesign® standard.

70 D Taslan

The used 70 D Taslan Polyamide has been engineered to look and feel more like cotton. This fabric is wind resistant and resistant to penetration by water. It is breathable making it comfortable for next to skin contact. The weight is around 110g/ square meter causing this fabric is less clingy than lighter ones.

  • * D stands for denier. This describes the yarn weight. 600D corresponds to 600 grams per 9000 meters.
  • * PES stands for polyester. PES fibres are very tear and abrasion resistant and hardly absorb moisture.
  • * PA stands for polyamide. PA fibres are extremely durable and abrasion-resistant. They are also characterized by high elasticity and low weight.

-3° C
THE LIMIT TEMPERATURE is based on the lowest temperature at which an ‘average’ adult male (25 yrs. / 70 kg / 173 cm) can expect to sleep comfortably in a relaxed position. An experienced user can optimise the insulation qualities by his choice of clothing and further factors.
