A warm night’s sleep for taller people (>185 cm). The extra-long Astro down sleeping bag offers just that, thanks to a trapezoidal baffle system that keeps the down in place to prevent cold spots, ensuring you stay cozy and warm – even on cold nights. We only use down that carries the Responsible Down Standard (RDS). The Astro is also a bluesign® product, manufactured to strict environmental and social standards, with minimal impact on people or planet.

30D PA
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.

  • * 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.
