Spark Down Sleeping Bag

[This review was collected as part of a promotion.] I plurchased this for a fast thru hike on the Superior Hiking Trail. Nights got down to 40 degrees. I-was a little worried about the chill and the bag rating since I'm a t-shirt underwear and sometimes socks guy. But this was perfect. Finally a bag true to its rating. Yes my tent was small and my pad reflects heat as well. but the bag was warm and comfortable and packs down sooo crazy tiny.
