Son loves it

I've used it several times

My son is 11 and has used this bag on 3 trips so far. Canoeing trip, 2 night, in 50’s and humid. Winter car camping 18f night with thick alpine pad and 3 day backpacking trip with nights in high 20’s/mid 30’s with an insulated big Agnes air pad. He wore merino wool thin base layers most nights and was fine. It weighs 3lb 1oz. He likes that he can attach it to his pad. I like that it’s affordable and synthetic in case he accidentally gets it wet. It’s too tight for me to use, at 6’2” and 190lb athletic build.

Wonderful bag

I've used it several times

Got for my son, 1st "real" (not box store) bag. Nice materials, good fit. Haven't taken it down below 50* yet, but he says he was comfortable. Stuffs pretty small for synthetic bag. Not too bad on weight.

Hi David, can you tell me if this bag fully un-zips into a traditional blanket as well?

Can you zip 2 together?

Hey Greg, if you can find a left zip bag to go with the right zip bag then you should be able to zip them together.
