I have a lot of trouble with most wools (and wool blends) being too scratchy to comfortably wear.
Since the wonderful-feeling wools are not in my budget, I usually go with an acrylic yarn. (I'm planning my next sweater out of Bernat Satin, which feels lovely).
I usually get odd looks from people in the shop, becuse the only way I can really tell is to rub the yarn along my inner wrist to test for "scratchy-ness".
(as a courtesy be sure not to be wearing any perfume when you do this)
Perhaps drag him to the shop and test it on him before you buy?
