Sea To Summit Spark SpI Down Grey Yellow

If you’re looking for a high performance sleeping bag, but don’t want to be weighed down by a sleeping bag, our Spark™ line bags are for you.
Ultralight and technical, our Spark™ line sleeping bags are designed to keep you as warm as possible while optimizing their weight and size once packed. Products in the Spark™ line encompass both ultralight liners and mid-winter expedition sleeping bags. While their end use is very different, these products reflect a design philosophy of combining weather conditions with sleeping bags that are as light as possible.
