Sea to Summit Comfort Blend SP Liner Rectangular

The Sea to Summit Comfort Blend SP Liner Rectangular combines the softness of cotton with the resilience of polyester, creating a liner that adds real warmth and protects your sleeping bag from dirt and wear. Unlike plain cotton liners, the 80/20 blend dries faster, resists shrinking, and maintains a smooth hand feel even after repeated washes. The rectangular cut provides generous room for side sleepers and restless movers, while the included stuff sack keeps the liner compact for travel, hostel stays, or backcountry trips.

Highlights

• 80% cotton / 20% polyester blend: soft, breathable, and durable
• Rectangular shape with 185 x 92 cm dimensions fits most standard sleeping bags
• Adds up to 4°C (7°F) of warmth, extending the comfort range of your bag
• Machine washable for easy hygiene maintenance on long journeys
• Includes a compact stuff sack (18 x 10 cm packed) for effortless packing

In daily use

Slide into the Comfort Blend SP Liner and feel the difference: the brushed cotton surface is gentle against skin, while the polyester fibers wick moisture and speed up drying. Use it alone in warm hostels or hotels, or pair it with your sleeping bag to reduce cleaning frequency and preserve loft. The rectangular design avoids the confining feel of mummy liners, making it ideal for campers who value freedom of movement. After the trip, toss it in the washing machine and store it in the included stuff sack—no special care required.
