I recently picked up this set of quilts from HammockGear.com as an integral component of my ultralight backpacking setup. The Phoenix is a 3/4 standard length quilt that weights just 11.7oz. The Burrow is a size short top quilt that weights 11.3oz. Both quilts are rated for 40F. The unique design of the HammockGear under quilts contours to your actual body shape as you lay in the hammock (this is called a differential cut). Thanks for watching!
