Kelty Lightyear +25 and +45

    Just used my two new sleeping bags for the first time one week ago. I like to sleep cold and my lady friend likes to be warm so she used the +25 and I used the +45. Both of us slept on 1.5 inch self-inflating matresses (Pacific Outdoors full-length and Thermarest 3/4) in a Big Agnes SL2. Temperature was reported at 38 degrees F. We both froze our butts off. Are these ratings for these bags "comfort" or "survival,i.e. you won't freeze to death".
    The next night we slept with long johns, socks, and beanies. Luckily it warmed and was only uncomfortable for 1 hour.
    To be fair we are from Florida. If you're from Canada you might be happy with these ratings but I will add 15-20 degrees to these ratings.

    Not bad, but not a 25-degree bag

      I(male)have slept in a Kelty Light Year 3D about 20 nights in the past year in Gulf Coast weather ranging from hot and sticky to sub-freezing and dry. It should more appropriately be rated a 40-degree bag. Don't get me wrong. It's a great super light synthetic "second bag" for moderate temps, but not lofty enough for a truly cold night, even with clothes on. Get a good 800-900 fill goose down bag for those cold nights you don't want to wake up chilled to the bone.

      Mmm Mm Good

        This sleeping bag definitely kept me warm to its rated temperature. However, at first I hadn't cinched the drawstring around my head real tight so I was losing a lot of heat. But, when everything is properly tightened up it was most comfortable. Also, a very light sleeping bag so it’s excellent for backpacking. I would recommend this to any 3-season backpacker.

        Great Bag!

          This Kelty bag was the 3rd one that I tried this season, and it's definitely a keeper. It's warm and roomy and packs light for backpacking. The 25F rating is right on, but don't think it will keep you warm at temps any cooler. It's definitely a 3-season bag. It's a high quality bag and also looks pretty sharp when it's unrolled in your tent. I highly recommend!
