Does anyone have or has had one of these? I am still contemplating a fleece liner to use with my Nanok for additional warmth. It seems to be a top entry whereas my Nanoks are side enrties.
Please discuss:)

Hi. Ive got one of these. Mine definately makes a difference to the warmth of my bag. Whether its as good as stated in the blurb I dont know. Are there cheaper options, yes. Experiment with poncho liners, fleece liners. Would I recommend to a friend...Yes. Why, well for me it does increase warmth, it packs small and its light and fits my purpose. I hope this helps.

I've had mine for a year or two and have used it several times. It's a really good option when you just need a little temperature boost without needing to carry a bigger and heavier bag, or having to buy a lower rated bag if you only have one sleeping bag. Plus, it's really small and light. It's kind of expensive for what it is, but still cheaper than buying a new sleeping bag. I last used mine in December 2011 in conjunction with a 32 degree bag. I think the low that night was around 19 degrees and it kept me warm and comfortable all night. The temperatures are in Fahrenheit; as I have no idea what they would be in Celsius.

Yes it's a top entry bag with a drawcord.
Yes it does feel warmer in a sleeping bag with it.
Does it add 14 degrees to the temperarure of the bag,I don't know bvut if you sleep in it on its own you'll be cold ,even at 10 degrees.

Had mine for a few years and use it often,it makes me feel warmer and packs really small and light so it's always in my pack.
