David B.wrote a review of Mountain Hardwear Lamina Z Sleeping Bag: 34 Degree Synthetic on August 12, 2017
Familiarity: I've used it several times
Used it three nights in the Sangre de Cristo Mountains near 11,000 feet. It kept me toasty warm in my hammock (with under-quilt) in 42 degree nights with wind and rain. It compresses very well, fluffs up easily, and is lightweight. I love it.
