no insulation required under the legs?

"I picture a top bag as an extension of the strung bow shape. In a cross section of the top bag, the pad in the sleeve assumes the shape of the taut string, and the bag part assumes the shape of the bow. Extend this cross section into the third dimension and you have a non-round hole into which one must insert the round peg of the human body."
Top bags with the pad inside them have to have this problem. My top bag lies ontop of a 3/4 exped down mat, with a 6mm foam mat sleeved onto the base sheet below the down mat. The top bag has down under both edges of my body but extra girth. the base sheet has elastic under it.If it is cold I can let the elastic crumple the base sheet and pull the down close around me. There is no possibility of the draughts that you might get with inexpert use of a quilt. (I am not sure of my expertness when drowsy).

Why suffer with this admitted "problem" when you don't even save weight?
Western Mountaineering SummerLite 19oz $300
Marmot Hydrogen 21oz $309
Montbell Super Stretch Down Hugger 23oz $270
Feathered Friends Merlin 23oz $314
Rab Top Bag AR 20.5oz $200

I think you need to compaire within a brand.

My Pod 30 offers the same weight with similar loft at the summerlite. However it also provides enough room so I can wear an insulating jacket inside.

how dare you guys hijack my thread! :D

But I admit that I am enjoying learning pros and cons of quilts, bag, and topbag. So you guys can have this thread as I just started a new one.

Robert "Why suffer with this admitted "problem" when you don't even save weight?"

I was pointing out that I don't suffer this problem.
I do however save weight. I turned a 850 gram rab 400 into a 980 gram double top bag and saved 720 gram between us.

Husefa,
In saving the thread from unarmed hijackers, do you know the weight of this Pashmina material? Total weight or weight per yard of material… just trying to get an estimate. I saw the shawl link above, but was more interested in blankets on the same site. I think one of those might be a nice optional layer of warmth for someone with a light quilt or top bag.

I have a Pashmina shawl that I use at home and it does itch, so maybe it isn't 100%. It does keep me warm, though, and I love it. It was a gift from friends who bought it in India.

Pashmina (cashmere wool)
As it is with Merino wool there is a huge difference between the best and the worst. The "100%" pashmina label means nothing. A lot of what is sold as 100% pashmina is blended with silk, up to 50% or even fully synthetic (viscose/ artificial silk/rayon)
The passing of a shawl through a wedding ring test is rubbish. I have seen that done with a 50% blend and even the synthetic version.
I spent a few hours in Katmandu with a friend of a friend that owns a shop that sell all of the above.

Cold feet ? wear a hat.
Next cold day you get put a warm hat on and see what happens…
Having one leg over the other just reduces circulation , the same is with tight socks.

Franco may be right. Some relatives of mine just came back from Kashmir. I asked them last night if they found any Pashmina and they said really good Pashmina they saw costed $2000+!

It may be that they werent buying at the 'source' but still vast differences in quality exist. Best buy safe and get those BPL UL merino.
