Tried and trusted
I have several of these. I live in Texas but travel to extremely low climates with Wildlife Photography. They all pack small and retain body heat. I love the Sherpa for home use and use the puffy for travel. I of course have extreme cold weather gear, but I always bring a rumpl just because. It’s a great product and I have 5 at this point. Heading to the North Pole next year and I’ll bring my bear rumpl just to have one with me.
