Sestrals Trousers

The dream of the ultralight backpacker: a pair of comfortable synthetic insulated trousers that keep you warm in wet conditions.

They are not only trousers.

As Tucas Sestrals Trousers are a pull-on style pant to be used as a core insulation piece. It allows you to:

  • Keep your legs cozy in really cold scenarios.
  • Boost your warmth while hanging around camp, cooking or resting.
  • Extend the temperature range of your sleeping bag or quilt.

A streamlined design. Functional details.

We designed the Sestrals trousers with simplicity and minimal weight in mind: a simple but effective pull-on style, no zippers and zero pockets.

However, we didn't go too far and retained a few but essential details:

  • A fully elasticated waistband keeps trousers where it should be.
  • By using a press stud ankle adjustment you can get a close fit against footwear and regulate ventilation.
