Nylon jacket with zipper pockets, size 3L, black. - Color: Black - Material: Nylon - Size: 3L - Features: Zipper pockets - Brand: Trico Tech Workman I bought this without trying it on, but it's a bit tight in the shoulders and arms for me, so I'm giving up on it. I've only used it twice for driving. I haven't done any work in it. The fabric uses urethane fibers and stretches a lot. It's a jacket for spring and autumn. You can even wear it in early winter depending on the inner layers! Thank you for looking.
