Sea to Summit Reactor Fleece Sleeping Bag Liner Mummy Grijs

Product Description

Prepare for cold overnight adventures with an extra layer of insulation designed to optimize your sleeping comfort. This technical fleece liner offers exceptional thermal performance when temperature levels drop significantly. It is designed to extend the overall warmth of your standard sleeping system, making your outdoor nights far more comfortable during challenging weather conditions.

The mummy-shaped design aligns efficiently with the body to minimize cold spots and lock in warmth where it matters most. Thanks to its versatile structure, it can be adjusted easily depending on changing overnight climates. Whether utilized inside a primary sleeping bag during harsh winter expeditions or used as a standalone layer on warmer nights, this gear adapts smoothly to your personal preferences and surroundings.

Technically engineered with Thermolite Pro hollow-core fibers arranged in a specific grid pattern, the fabric captures heat without adding excess bulk to your pack. The integrated shoulder zippers and an adjustable drawcord footbox provide precise ventilation and temperature regulation. The footbox allows the user to open the bottom entirely, providing the unique advantage of walking around the camp area while keeping the main layer on.

This product features a specific shape optimized for thermal efficiency and integrates seamlessly with the Free-Flow Zip system found on compatible Sea to Summit sleeping bags. Equipped with HeiQ Fresh odor control technology, the fabric stays fresh even after multiple days of continuous outdoor use, maintaining proper hygiene standards throughout the trek.
