I have the Mono Vertigo and I like it. These days though, it may cost almost as much as your S-281.
I had a great experience buying a more typical/inexpensive gig bag, that is pretty high quality for what it is...for my Pilot bass, from this somewhat questionable/sketchy reviews website around Black Friday. I got the gig bag for less than $10 delivered (is probably a 30-50 dollar gig bag). Have you heard of teemu? I think they ship directly from China and basically follow zero laws if there are any,regarding free trade or what have you. the deals are just totally insane, but many of the reviews are negative. I would not buy anything that requires any customer service or to suit a significant preference, whatsoever. basically anything you buy is a gamble...but I had the 10 bucks to gamble, for a gig bag that would likley be fine, as long as it showed up at all...thankfully I was right. But for example if you buy a blender and it shows up and doesnt work, or is a different blender than the one you ordered...too bad. If you buy a 50 pack of Ernie ball strings for $5.00, you may get 50 packs of strings...but they may not be Ernie Balls, or they may be fake Ernie Balls...understood? but for a gig bag at the right price, there is not much that can go wrong, other than the thing just not showing up.
here's the link, good luck!
