Eureka Casper

The Eureka Casper is rated for 15°F, and its EN limit is 17.7°F, which means it is designed to keep an average user comfortable in those conditions. However, personal warmth varies, so if you are a cold sleeper, we recommend using a sleeping pad with a high R-value to prevent heat loss through the ground.

Yes, the Casper is designed to be mateable with other compatible mummy bags. This is a great feature if you are camping with a partner and want to share warmth, though keep in mind that joining bags can sometimes create small gaps where cold air might enter.

The Casper weighs 3.81 lbs. While it is certainly packable thanks to the included compression sack, it leans toward the heavier side for ultralight backpacking. It is an excellent choice for car camping or shorter treks where warmth and comfort are higher priorities than shaving every ounce.

The peached polyester lining has a soft, brushed texture that feels much more like cotton sheets than standard, slick nylon linings. It reduces that 'sticky' feeling against your skin, making it significantly more comfortable when you are sleeping in base layers.

Yes, the maximum user height for this bag is 72 inches, which is exactly 6 feet. If you are right at that height, you will have a snug fit, but the ergonomic 3D footbox is designed to accommodate your feet naturally without cramping.

The Casper features an anti-snag guard along the zipper draft tube specifically to prevent the fabric from catching. While no zipper is completely immune to snags, this design significantly reduces the frustration of getting stuck while trying to zip up or down in the dark.
