Thomann Rain Cover Western Gig Bag

Needed this as I commute with my guitar, a standard sized acoustic steel string guitar, mainly by cycle, and rains can be quite annoying with a guitar bag with a cloth-based outer layer.
Pros:
It does protect my guitar bag from the rain.
Cons:
Size. I was told this would be slightly flexible to adapt to standard guitar bag sizes, but I have to put in a significant amount of effort to put this cover on my guitar bag, as it's either slightly smaller or just the same size as my guitar bag. Taking it off is also a bit of a task due to the tight fit.

I got this to cover my acoustic guitar which is in a Thomann gig bag.

I was disappointed that it is very difficult to put on and take off, and it doesn’t cover the back.

Also you can’t use the handle to carry the guitar. Couldn’t find anything else at a decent price, so I use it anyway. Not sure how long it will last though.

I bought the cover so that I could protect my Duesenberg Starplayer TV case (which is covered in fabric). The cover, although made for a western guitar, barely fits the Starplayer case.
