yes, I think you right i should be toasty. Its a wile since I've looked at the instructions but I though it was around there but only if you had your army cold weather gear on. LOL I'm curious now will have a look and see, let you know later. Not that we will ever get down to anywhere near that sort of temperature in the UK maybe -10 /15f. You're up late everyone ok CarlThat will be toasty warm, I think the 3 together are rated down to -45*f
