Excellent product, very warm
I bought this for my baby girl - ordered it not long after she was born. I got the lowest temp rating and digital camo/dayglo orange (why? because I could!)
Last weekend I used it myself, inside my down sleeping bag, because I realised on a camping trip last year how incredibly warm this thing is for its weight. I camped out in -15C (5F) and with this added to my sleeping bag I was as warm as I would have been at home. Later, when it hit -21C in the city I had this in bed too! Obviously it's a bit small for a full grown adult.
I look forward to using this with my daughter this year now she's turning one, and I am extremely confident it will keep her warm.
Also, I want to commend the quality of construction & materials, which are excellent. Last, I got great service from the EE team, who happily shipped this to my US office so I could collect it on a business trip and not have to worry about shipping it to where I actually live.
Thank you, and I am very pleased.
