Q: Judging from the picture, this jacket looks like it is more fitted (cut slimmer around the torso) than some other CWU/45P jackets. Does this jacket have a slimmer cut, or is it just the camera angle?
A: I would say the jacket is slightly fitted, but not to the extent that this should affect which size you buy.

Q: what is the difference between waterproof and water repellent?
A: Water repellent means it will resist water up to a point, but it will eventually seep through if exposed to enough water (a torrential downpour or immersed in water). Water proof means no water can pass through the fabric at all.

Q: Is the Inner Lining of the Jacket the standard Orange colour?
A: No, that's the MA1 jacket you're thinking of.

Q: Is the zip a real brass zip? What does it say on the zip? Does it say Delta on the zip? What is the distance from armpit to armpit on a large? What is the distance from armpit to end of cuff on a large? Is the outer shell tough nylon, like the Alpha? I have noticed, from having a couple these jackets, from other sources, that the outer shell varies in quality. I want the outer shell to be tough, like the Alpha.
A: The zip is a heavy duty brass zipper that has the wording Delta Ind. written on it. The distance measured armpit to armpit for a size large jacket is approximately 26". The distance from armpit to cuff is approximately 20.5". The outer shell is 100% nylon and is of a good durable quality.
