Sea To Summit Reactor Liner Mummy with Drawcord Sleeping Bag Liner
Seal in the Warmth, Sleep Through the Night – Sea to Summit Reactor Liner Mummy with Drawcord in Yellow
The Sea to Summit Reactor Liner Mummy with Drawcord Sleeping Bag Liner is the smart mid-tier upgrade for campers and backpackers who want the warmth-boosting benefits of a mummy liner without stepping up to the full Extreme Reactor. The mummy shape with integrated drawcord seals heat around your head and shoulders — eliminating the cold drafts that a rectangular liner can't address — while the Reactor fabric adds meaningful warmth to your existing sleeping bag. The bold yellow colorway is easy to spot in your kit, and the Regular size fits most mummy sleeping bags comfortably. A practical, well-priced upgrade for three-season camping.
Size: Regular | Color: Yellow | Condition: Sample – Brand Sample, Never Sold at Retail | Original Retail: $75.00
Key Features:
- Reactor Liner Fabric: Adds meaningful warmth to your existing sleeping bag — a practical temperature rating boost for three-season camping conditions.
- Mummy Shape with Drawcord: Contoured cut and integrated drawcord seal heat around your head and shoulders — no cold drafts, no heat loss at the top of the bag.
- Temperature Rating Boost: Extends your sleeping bag's usable temperature range without the weight and cost of a new bag.
- Standalone Use: Works on its own as a sleep layer in warm conditions, huts, hostels, or anywhere you want a clean, comfortable sleep surface.
- Sea to Summit Quality: Trusted by serious campers and backpackers worldwide — built to the standards of a brand that takes sleep systems seriously.
Ideal for the three-season camper or backpacker who wants a mummy liner with real warmth-boosting performance at a fraction of the retail price. As a brand sample, this liner has never been sold at retail — you're getting a pristine Sea to Summit Reactor Liner Mummy at nearly 47% off the original $75 price. The right upgrade for the camper who wants more warmth without more weight.
