Ultralight, compact and versatile, Sea to Summit's latest range of sleeping bags and liners are built for all seasons, terrains and adventures. From ultralight hiking to car-camping comfort, find the sleeping bag that really fits you–and your adventure.
The 2024 technical liners with a Mummy shape now feature shoulder openings and a drawcord in the foot section, which complement the innovative Free-Flow zippers found on their mummy sleeping bags. You can easily reach your arms through the openings or sleeping bag zippers to enjoy a cup of coffee in your tent. Additionally, you can utilise the shoulder openings for extra ventilation to adjust your temperature. The liner also has a base drawcord that can be opened, allowing for simpler middle-of-the-night bathroom breaks.
