Specifically speaking, the Lynx is constructed specially for weight sensitive backpacking or bikepacking pursuits, but it doesn't compromise on comfort or performance so whether you're thru hiking the AT or bikepacking from New Jersey to Maine, this sleeping bag steps up to the challenge with ease.
