Way I look at it, $40 for a wool version of the sweater seems worth it...$10 difference between wool and acrylic. I looked at a couple of sweaters at the Army Surplus shop a couple of weeks ago...hard to find one large enough and I'm only a 42 chest "large". Also only available in OD or Air Force Blue and in the $20-$25 range for a used-but-in-pretty-good-shape garment. Sort of a cost/benefit analysis kind of thing.

Walkerk mentions a Bridgedale version...I actually have a khaki colored heavy sweater made by Jaeger (apparently a UK company) that my dad actually wore when he flew in the Second World War...still in very good shape even though I wore it through college. Some things were made to last.

Best
