me considering the price ($269) and weight (1 lb 10 oz). I pair it with the NeoAir® XTherm™. Very pricey but worth it to never be cold with an R Value of 5.7 and light (1 lb). I hiked Kings peak in Sept with this combo and I was toasty warm after like an inch of hail fell on our camp.

I bought a Marmot plasma bag that is even lighter but never took the tags off because it was just too expensive and not as comfortable.
