Ultra lighters come drool with me.
The Alpkit pipedream sleeping bag is geogous. VERY lightweight and a rather fetching black with red trim. quite snug on width but has fullength zip and we got 1 R and 1 l handed so we could even zip together! such excitement, it was like christmas. And yes we did both try them out ;-)
We have been umming and erring over what lightwight bags to get for cycle touring for a while, nice to have something so sexy to show for our reserch. Boys growbag and flease blanket weigh more and take up more room tho. ho hum, not worth getting him a down bag just yet.
