The size medium has long sleeves. My shirt sleeve length is 33-1/2, and I like the longer length for handlebars. The buttoned-flap eliminates any air passing through the zipper. The lining is porous-oxford, medium weight, and durable cloth. I wore it right out of the bag. The front hand pockets aren't very deep. The chest pockets are only deep enough for Marv petite pen, and still be able button the flap. A 3x5 spiral tablet won't fit. The map pocket is as deep as any. Preshrunk, pineapple-weave (firehose) canvas. Will age.
