Finding the ideal balance of comfort, innovation, and performance, Eureka's Lone Pine 30 Sleeping Bag boasts Insulcore HQ insulation for dependable warmth in most conditions and a tough polyester fabric for years of durability. A Eureka Stealth Grip bottom prevents this bag from sliding all over the place in the middle of the night. Eureka also focused on comfort when designing the Lone Pine's shape, blending the thermal efficiency of a mummy bag with the wiggle room of a rectangular bag. Plus, additional width in the hip, leg, and foot area lets you get comfortable while still keeping you warm. The insulated face baffle and draft tube boost your warmth even further, while the compression stuff sack makes for easy packing when you're headed on to the next site.
