Spark SpIV Sleeping Bag

Our Spark™ Series bags is what you reach for when you need a high performance sleeping bag but don’t want to be weighed down by one.

The Spark™ Series spans everything from an ultralight liner to an expedition weight mid-winter bag. While the end usage is very different, they reflect a design ethos of matching weather conditions to the lightest bag possible.

Ultra-light and technical, our Spark™ Series bags are designed to keep you as warm as possible while minimising packed weight and size.
