Sea to Summit Latitude II

Cut ounces and sleep comfy.

Brand: Sea to Summit

Model: Latitude II



2lbs. 8oz.

Fit For testers who find mummy bags tight and rectangular bags inefficient, the Sea to Summit Latitude II’s dimensions are just right. We especially noticed the extra space in the footbox, where a 43-inch circumference offers lots of legroom over the average mummy. “I sleep warm, so I’d much rather have extra legroom than a cramped footbox,” says our Colorado tester. Nice touch: The two-way side zip wraps all the way around the bottom and there’s also a separate two-way footbox zip.

The 750-fill Ultra Dry duck down insulates well in subfreezing temps. “I was able to sleep with no cold spots through the entire night, every night,” says our tester after multiple trips in Alaska and Utah. Want warmer? It’s also available in a 1°F version for $50 and 6 ounces more.
