Perfect for my 5’7 145-lb frame!
I had to pack a sleeping bag, a sleeping pad, a pillow and my climbing harness and climbing shoes in my Mammut Trea 35-litre backpack for a climbing trip. Therefore, I need a sleeping bag that compresses down to 8-9 liters in size, but is warm enough for overnight temperature in the 40-50’s. Tom at REI rental recommended this sleeping bag, which fit my frame perfectly, but was already reserved by another customer. I decided to buy one because the rental fee for a week is already half of the cost of a brand new sleeping bag, It turned out to be the perfect size for me! In the past I have rented a regular adult size, but I was swimming in the bag. I was misaligned every time I turned. Zephyr kid’s sleeping bag is perfect. It moved with my body. The neck warmer worked so well to retain my body heat. The price is better than the adult size. It packs small. I cannot ask for more! I highly recommend this sleeping bag for adult women in similar or smaller size!
Lightweight but not for temps below 40F.
Nice and lightweight but not particularly warm for temps below 40F. My son had a Boy Scout overnight trip and it dipped into the mid-30s and he was quite cold with this bag. He used a sleeping pad with a 5.5 R value, so I don’t think that was the issue. The bag, while rated for 25F, is definitely not the best choice for temps below 40F.
