On first looks I dont like it, im not convinced on the claims. Regarding the main claim and selling point of the bag which is ''moving around in it comfortably like in your bed at home'' well I just cant see this, you still cant spread your legs apart like you can in your bed, in a mummy bag the main constriction is not being able to spread your legs apart but you still cant in this bag either (as clearly proved in the video), you need a rectangular bag for that. And personally despite the vids attempts to convince me that I have had uncomfortable nights in a mummy bag, actually I dont find ordinary mummy bags uncomfortable at all, and its easy enough to leave a zip open on a mummy bag to regulate heat.
Other reasons for not liking:-
- Weight -- 1130g or 1390g (depending on model) is quite heavy for a down bag (it has down fill) with a comfort rating of only -1 centigrade.
- Pack size -- suspect high volume (I may be wrong), stats say stuff sack is 38cm x 20cm (though it doesnt say if thats compressed or not), thats big for a down filled bag.
- For wrigglers in their sleep like me I suspect the inner quilt could easily be pushed away from your body as you toss around, if it did you would wake up prematurely feeling chilled resulting in a poor nights 'disturbed' sleep.
- You cant cinch the hood down so I suspect you would get drafts and heat loss as you move (and its designed for movement).
- Suspect large internal volume (to allow for its claim of comfort) which may cause cold spots.
- I dont like the hand pockets to tuck and keep bag in place, when you move in your sleep they could pop out and bag could move away from your body, a zip is better as you dont have to concentrate on keeping your hands in one place to keep bag in place, if you have to ''think'' about keeping something in place then you wont sleep well, when I retire to my bed I sleep best if I dont have to ''think'' about anything at all.
- Im also a little confused by the warmth ratings and cost between the two models available, they are both 3 season bags, the 600 model costs £191 ($299.95) and has a comfort rating of -2, however the 800 model costs £255 ($399.95) and has a comfort rating of -1, im guessing the cost and weight differential is probably due to the quality of down in each model as the warmth rating is similar in both.
Judgement is best made with hands on experience of course so it may perform better than it looks, my opinion is just based on viewing the link. Im guessing it would be suitable for car camping/fixed camp etc but for hiking I think there are better alternatives.
