Pouches for MP-38/40 were made of cotton or rayon thick fabric (tarpaulin). The color of the fabric could be different shades of green, gray, brown, khaki. The Luftwaffe pouches could be from gray (blue-gray) material. The skin could be either unpainted (natural vegetable tanned leather: light beige colour) or dyed: brown or black.
Pouches with textile straps were not uncommon.

Until 1942, the Y-belt belt ring was sewn into the corner of the pouch.
From 1942, the ring for Y-belt was moved to the side of pouch with the special strap. It gave more freedom to a soldier when moving with fully filled pouches.
Also completely leather pouches are known, they were produced in 1941-43. Below is a photo of the original leather pouch with the evg42 stamp from fjm44.com:
