Product Description

Sea to Summit Reactor Lightweight Sleeping Bag Liner – an extra boost of warmth for your sleep system

The Sea to Summit Reactor Lightweight Sleeping Bag Liner is designed for minimal weight and maximum thermal performance. It enhances your sleep system with advanced Thermolite® Pro fabric. Infrared-absorbing ceramic pigments and hollow-core fibres help retain body heat, adding up to 4°C of extra warmth while keeping packed size to a minimum.

The stretch-knit fabric and pre-shaped arm openings provide unrestricted freedom of movement and excellent sleeping comfort in almost any sleeping bag. Thanks to HeiQ Fresh odour control, the liner stays fresh even during extended use, dries quickly and is easy to care for – ideal for demanding adventures. It also helps extend the life of your sleeping bag by reducing the need for frequent washing.

Features:

  • Ultralight warmth – Thermolite® Pro retains body heat and improves sleep system performance by up to 4°C
  • Maximum freedom of movement – Stretch-knit fabric and ergonomic arm openings for natural sleeping comfort
  • Ergonomic hood – Close-fitting design provides additional warmth without extra weight
  • Fits almost any sleeping bag – Stretch fabric for versatile compatibility
  • Long-lasting freshness – HeiQ Fresh technology helps reduce odour build-up, even during extended use
  • Sleep system integration – Shoulder snaps allow easy attachment to Sea to Summit sleeping bags
  • Easy care – Machine washable and quick-drying
  • More sustainable materials – Made from recycled fibres and bluesign® APPROVED materials

Note:

This liner does not replace a sleeping bag. Instead, it complements your existing sleep system and adds up to 4°C of warmth.

Sustainably packaged.

Nature is very important to us. That's why we avoid unnecessary plastic and rely on packaging material made of paper or cardboard. If your package does contain plastic filling material, this is material from our suppliers which we have reused.
