A true multipurpose piece of gear.

A great way to lighten up your backpack is by using multipurpose gear. The As Tucas Millaris Bivy Sack excels in this area:

  • Increases the temperature rating of your sleeping bag, allowing you to carry a lighter one.
  • Replaces a ground cloth, simplifying your kit.
  • Offers full bug protection.
  • Can be used alone in warmer climates.

Keeps your sleeping bag clean and dry, naturally.

The new schoeller®-ftc fabric with ecorepel® finish provides a very high level of water and dirt repellence, without reducing fabric breathability.

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

Aesthetic design. Functional details.

The Millaris Bivy Sack was designed with beauty, simplicity of use and minimal weight in mind:

  • Three hood styles: full fabric for maximum protection, full mesh for maximum breathability and mesh window for best compromise.
  • Half-length YKK zip for easy entry and exit. Double pull increases ventilation options.
  • Bathtub waterproof bottom for maximum protection. Corner loops help keep the bivy sack in place.
  • Overhead hang loop to increase air flow and space around your head.
