Sea to Summit Breeze Sleeping Bag Liner – Standard Mummy with Drawcord

Sea to Summit Breeze Sleeping Bag Liner: Comfort, Hygiene, and Versatility

The Breeze liner combines a rectangle-cut design with stretch-knit fabric to move with you, even as you shift and roll. Its thoughtful construction includes a built-in pillow sleeve, so you can rest more comfortably wherever your head lands. Its compatibility with Sea to Summit bags' Free-Flow Zip system means you can tailor the fit to your sleep setup without swapping gear.

Key materials that balance dryness and softness

At the core, Coolmax Ecomade fibers wick moisture away from the skin, helping you stay drier in humid climates. A TENCEL Lyocell blend adds luxurious next-to-skin comfort while keeping an eye on environmental responsibility. The knitted fabric delivers notable stretch, promoting a less restrictive night’s sleep and freedom to move as you wish.

• Coolmax fabric technology keeps you dry and comfortable by wicking moisture from the skin
• TENCEL Lyocell fiber offers soft, breathable comfort with a sustainable approach
• Knitted fabric provides excellent stretch for unrestricted movement

Freshness and ease for longer trips

HeiQ Fresh odor control helps maintain a fresher feel between washings, supporting a cleaner sleep environment during extended use. A built-in pillow sleeve keeps your head and neck supported, reducing the need for extra accessories and helping you settle faster after a long day.

Designed for real-life sleep, indoors and out

The drawcord footbox can be opened or closed to dial in comfort and temperature, and it integrates with the Free-Flow Zip system on compatible Sea to Summit sleeping bags. This makes the Breeze liner a versatile companion for hotel rooms, hostels, camping trips, or backpacking adventures—allowing you to preserve a familiar sleep feel wherever you rest your head.

Sea to Summit also offers a lifetime guarantee on this liner, underscoring its durable build and ongoing value for travelers who prioritize a hygienic, adaptable sleep setup.
