Sea to Summit Comfort Blend sleeping bag liner Rectangular w/Pillow Sleeve, TENCEL blend breathable stretch-knit

The Sea to Summit Comfort Blend Sleeping Bag Liner is a lightweight rectangular liner with a built-in pillow sleeve that boosts warmth, hygiene, and sleeping comfort while camping or travelling.

Whether you’re backpacking, staying in hostels, or simply want a cleaner layer inside your sleeping bag, this liner blends TENCEL Lyocell and polyester for a soft, breathable feel. It’s designed to fit rectangular sleeping bags and doubles as a protective layer against hotel sheets. The fabric is treated with HeiQ odor control technology so the liner stays fresher between washes, and its stretch-knit construction gives you freedom to move without restriction.

How will this liner change my sleep while camping?

The Comfort Blend liner adds a softer next-to-skin surface and a small, insulating boost without bulk. It helps reduce direct wear on your sleeping bag, keeps you cleaner in multi-night trips, and is easier to launder than a full bag. The rectangular cut preserves your natural sleeping position and the stretch fabric follows your movements.

• Soft TENCEL/polyester blend for a silky, breathable feel
• Stretch-knit allows natural movement while sleeping
• Rectangular shape avoids constriction common in mummy liners
• Quick to wash and faster to dry than full sleeping bags

Will the pillow sleeve improve head support and hygiene?

The integrated standard-size pillow sleeve keeps your pillow in place and protects it from dirt and sweat. It’s a simple way to maintain a cleaner sleep setup when you’re moving from campsite to campsite or checking into hotels. The sleeve also prevents pillows from sliding, which is especially useful in narrow or uneven sleeping platforms.

• Standard-size sleeve secures a pillow for overnight comfort
• Protects hotel or hostel pillows from direct contact
• Helps reduce sliding on uneven ground or in bivy setups

How does odor control and fabric care work with this liner?

Sea to Summit treats the fabric with HeiQ odor control technology to limit microbial odors during extended use. This keeps the liner smelling fresher between washes, making it more practical for multi-day trips. When cleaning is needed, the liner’s lightweight blend washes and dries quickly compared with a full sleeping bag.

• HeiQ odor control reduces smells from perspiration and body oils
• Machine-washable fabric for routine cleaning
• Dries faster than bulky bag insulation, easing trip logistics

Is this liner compatible with my existing gear and travel routines?

Yes—the rectangular shape and neutral sizing match most standard rectangular sleeping bags and integrate easily into travel kits. It packs compactly, fits inside a daypack or checked luggage, and can be used alone as a lightweight sleeping layer in warm climates. The liner also serves as a protective barrier that preserves the interior of expensive bags and quilts.

• Fits standard rectangular sleeping bags and hotel bedding
• Lightweight and compressible for easy packing
• Protects sleeping bags from dirt, sweat, and wear

Who is this for? The Sea to Summit Comfort Blend Sleeping Bag Liner is ideal for campers, backpackers, frequent travellers, and anyone who wants a cleaner, softer sleeping surface without extra bulk. It’s particularly useful for those who share accommodation, rotate gear often, or value quick-drying, low-maintenance sleep layers on multi-night trips.
