【Ultra Thick & Soft Flannel】Made of high-grade flannel with long fleece on the skin-touch side & short fleece on the outer side, our sleeping bag liner delivers extreme softness and thickness for cozy sleep. The dual-texture design keeps you warm without stuffiness, perfect for cold nights in hotels, camping, or backpacking. It solves the discomfort of rough, thin liners and cold sleeping surfaces, bringing hotel-level comfort anywhere. 【Large Size Design with Dedicated Pillow Pocket 】Measuring 86 in long x 41in wide with a 20in pillow pocket, our liner fits tall adults and offers roomy space to stretch freely. The built-in pillow slot keeps your pillow fixed in place all night, no more sliding or adjusting. The large rectangular shape fits most standard sleeping bags while providing enough room for side sleepers and back sleepers—solving the cramped feeling of narrow liners. 【Invisible Side Zipper for Easy Access & Versatile Use】Features a smooth hidden side zipper that opens quietly and won’t snag fabric. You can use it as a standalone lightweight sleeping bag (1.2kg only) or a protective liner for your existing sleeping bag to extend its life and keep it clean. The zipper design allows quick entry and exit, ensuring convenient use. 【Professional Dirty Proof & Multi-Scene Portable Use】At 1.2kg, Our thick liner’s higher gram weight means thicker, softer, more durable material that resists tearing, pilling, and snagging far better than lightweight alternatives. The thicker construction creates a more effective barrier against unclean bedding, moisture, and cold surfaces, delivering a cleaner, cozier sleep experience. Our travel sheet is ideal for travel, hotels, hostels, camping, hiking, and outdoor adventures. 【Protect Your Warm Sleeping for Indoor & Outdoor Use】This thick, durable liner is not just a sleeping bag insert—it can be used as an independent sleep sack, warm sheet, or travel blanket. The thickened flannel locks in body heat effectively for cool weather use, while the soft, skin-friendly material is gentle for all-night use. A versatile, high-value essential for campers, travelers, backpackers, and hotel guests.
