Looking for snow,
Your typed English is just fine and if some people took the time to see your location: Lithuania it would explain any confusion.
Question: With your injury do you need full body or are you just trying to protect the back???
I would think you could go with just a back protector and not worry about all the other gear. With that and your injury I would start with the heaviest protection to cover your spine if that is truly a major concern.
