I would like to acquire some 100% wool commando sweaters (Kochanski's video influence) because they seem really functionnal and would fit perfectly with the old fashion system of wool pants with suspenders because of the reinforcing patches on the shoulder that are just perfectly positionned to withstand abrasion from the suspenders or backpack straps.

Do you wear them? What is your experience with them? What are good retailers?

L.L. Bean has a version with regular or tall option (I'm tall and often have problems finding sweaters and coats with long enough sleeves in this ready-made prêt-à-porter world) but seems less form fitting than the military original (this sweater is originally designed to stretch and fit snug as a bug to hold in body heat).

Brigade Quartermaster claim to have the original Woolly Pully® brand.

Any comments or trivia about them?

Thank you
