Sea To Summit Boab Sleeping Bag -9 deg. C Long - Olive

Synthetic sleeping bag in olive colour. Suitable for mountain trips, camping and overnight stays in a cool climate. The contoured mummy shape effectively reduces heat loss, providing effective thermal insulation and protection against the cold.

Temperatures and conditions of use

Operating temperatures of the Boab sleeping bag -9 deg. C Long determined in accordance with EN 13537:

  • T-comfort: -4 deg. C - the lowest temperature at which a woman can sleep comfortably all night,
  • T-limit: -9 deg. C - the minimum temperature at which a man can sleep without discomfort,
  • T-extreme: -30 deg. C - the lowest temperature at which you can survive in a sleeping bag. This is not a recommended value for standard use.

50D polyester with DWR coating, Revive Loft filling

Recycled 50D polyester with a hydrophobic DWR coating free of harmful PFAS substances is used for the outer layer and lining. The synthetic filling Revive Loft, based on fibres of varying thicknesses, is responsible for the thermal insulation properties, which translates into greater elasticity and more effective heat retention.

YKK two-way zip, plough zip guide

The model is equipped with a two-way YKK zip on the left side that extends to the foot area. This allows the sleeping bag to be fully unzipped, so it can be used like a duvet or the ventilation level can be adjusted according to conditions and individual needs. Additional protection in the form of a plough zip guide effectively protects the material from accidental zipping.
