If you’re searching for a plush, versatile and spacious synthetic bag for luxurious camping trips, the Basecamp Bc3 ticks all those boxes and more.

The Basecamp features a contoured rectangular shape so that you can stretch out comfortably, and has a shell and lining made from lightweight and compressible nylon. To keep you warm, this bag has layers of looped THERMOLITE insulation, which traps warm air for comfort. The webbing loop system allows you to connect your bag to your sleeping mat, and to stop you getting tangled, the lining is attached to the shell.

The three two-way zips on this bag allow you to separate the top and bottom layers so you can use the top as a quilt when the conditions call for it, or add ventilation to it. With a -5°C comfort rating and a -12°C lower limit, the Bc3 is suitable for colder sleepers or excursions in cooler conditions.

The roomy Basecamp BcII from Sea to Summit is the sleeping bag that prioritises comfort for a soundless sleep on your adventures.
