This is the second time I’ve bought it. I bought the first one in 2013 and it lasted until 2017, when I sold the bike, and it was perfect. Thick fabric, soft lining for scratches, waterproof. I bought it again around this time last year and after 1 year it just fell apart. It does spend more hours in the sun, yes, but within one year??? I was disappointed. Since I also had the bag from the previous one, which is made of the same material as the cover, I noticed that the new one also has a different color (lighter) and a different texture (harder). It is still waterproof. I’m not spending almost 40€ again for one year...

The covers should have 4 dimensions (length-width-height and the back side from the seat to the wheel). You just take a guess.
This one is thick, so I'll let you know since these specific ones don't even have dimensions and we go by the type of moto, I got the tc-e1 code 10360 which covers a Gilera Nexus 250 without a top case.
It covers the wheels all the way down, they can't be seen, and the handlebar is locked.
Maybe this helps you figure it out... anyway, it is thick.

The hood I ordered was for a motorcycle over 500 cc and they sent me a hood for an automatic. With great difficulty, I managed to cover the bike and it is so tight that it probably won't come off in the summer

I bought it for my Vespa gts in this medium size. It has padding, it's not just fabric where it will melt! It is thick and waterproof, for its price I think I couldn't find anything better.
