Sestrals Blanket

Even more functional and versatile than a quilt. Still ultralight.


Due to its variable girth and open bottom, quilts are much more versatile than conventional sleeping bags. The As Tucas Sestrals Blanket raises the bar thanks to an openable bottom, which extends its comfort range towards the warm side. This even allows you to use it like a flat blanket.

The Sestrals Blanket retains the successful design of our quilts. Thanks to its longer and wider dimensions, it is the most user friendly and the one that can be really pushed to its limit.

As smooth & light as silk.

The new schoeller®-ftc fabric sets a new standard in ultralight fabrics. It's not only highly windproof and downproof, but it's also amazingly soft to the skin.

  • Ecological: biodegradable and free from fluorocarbons (PFC).
  • Wash permanent and abrasion resistant: finish last more than 30 washing cycles at 40°C.


  • Longer than traditional quilts. Cover your neck and head as temperature drops.
  • Wider than traditional quilts. Move and roll without creating cold drafts. Perfect for side sleepers!
  • Openable footbox. 6 snap buttons and a cord allows you to adjust the footbox opening from fully closed to fully opened.
  • Redesigned footbox closure. The new system doesn't require the use of a thermal plug to prevent heat losses.
  • Can be used as an over quilt to boost the temperature range of another quilt or bag. In this case, we recommend the wide option.
