Doubts about a soviet tanker uniform.

Hello, here is a uniform I have some doubts.
Obviously it is a tanker uniform, in 50-4 size, I think is dated 1987.
CA in the shoulders, T55 right breast patch, T55 and star patch in left arm. Pentagonal reinforcement in knees and also a big reinforcement in butt.
The uniform is a bit saggy like it was the outer shell of a winter uniform, but i do not found any button for the liner.
Could be an winter uniform? or may be an work uniform to wear over the field uniform?
Thanks in advance.

The tanker's uniforms I recalled had an integral belt on the pants but it's been a long time since I collected this stuff so that could be only for the OD tankers uniform.

This doesn't look like the tanker uniform the more I look at it.

an interesting thread on tanker unis. I tcould be a winter uniform as the black summer uniform was pretty much like the od uniform above.

Very good link!
I like very much the OD uniform, I have one in very used condition and another in new condition. This is the used one:


I do not know if this are the matching pants, because the lacking thigh pockets.

This are the mint ones, with matching trousers ( I need to take a pic of the pants and belt):
