Description
The THERMOLITE® Reactor liner is our top selling and lightest thermal sleeping bag liner.
It's an excellent cold weather option for those who need additional warmth.
The hollow core fibres trap heat and offer extraordinary insulating properties.
This is a super stretchy, soft, and comfortable choice with a mummy shape, foot box and a drawcord hood.
Compact and lighter weight than fleece, this is a best seller for good reason.
