About the Sea to Summit Treeline TL1 - 3C

The Treeline TL1 sleeping bag delivers Sea to Summit's trademark cold-weather performance with a water-resistant breathable shell fabric and 600+ down insulation for backpacking and camping.

The Treeline TL1 range is designed with a relaxed mummy shape, giving extra room around the shoulders and hips for more comfortable sleeping, while weighing around 970g. This is ideal for those looking for a sleeping bag for summer outdoor adventures from trekking and wild camping to backpacking, at a great price.

The 600+ loft Down is a PFC-free treatment that absorbs 40% less moisture and dried 60% quicker than untreated down, while using horizontal baffles to keep the down where you need it for maximum warmth. Inside, a security pocket is perfect for stowing electronics to preserve battery performance in cold conditions. The Treeline TL1 is also designed to zip together with another bag.
