Review on Alplive T400 Ultralight Backpacking 32-50F Down Sleeping Bag - 27Oz Ultra Compact 650 Fill Power Envelope For Hiking, Camping And Backcountry - Lightweight & Compressible by Erik Haynes

Super light weight - great for keeping your pack light. Good looking bag with solid zippers. I used this sleeping bag throughout the summer, mostly in the Midwest states. I took it into the BWCA for a few days as well. The coolest night got down to 39 degrees F. I had to zip up tight and layer my clothes underneath. I got cold. I tend to get cold at night, so this might not be an issue for the warmer blooded camper. The material is super lightweight so it doesn’t hold form like heavier bags -and might twist around on you. The bag is quite durable and should last a long time if taken care of. I would suggest not using below 40 degrees F.
