    Quality material, great price

    • Familiarity: I've used it once or twice and have initial impressions

    I bought this item to add some warmth to a summer sleeping bag. It's great protection for the inside of my bag but I don't know that it added much in the way of temperature support. For the price though it was worth a shot.

    For context my summer bag is rated at 35 degrees and I was camping in low 20s.

    Unanswered Question

    Do you know how much "extra warmth" this liner provides? The description is a bit vague and I can't find a specific number listed anywhere online.
    Thanks!
