Mono Cases Bass Sleeve (ASH)

Bought this bag some time ago, and really like it. It's extremely well built and reassuringly sturdy. It's a very tight fit around the instrument, so there's very little play inside, giving you peace of mind that your bass won't be moving about. Zips are all rugged, everything seems well thought out and durable. It's also nicely stiff, so it stands up on its own and doesn't flop about when the bass isn't inside. That makes it really easy to get the bass in and out.

But there are some quirks. Because it's such a tight fit around the instrument, the headstock gets squashed by the padding, which will cause your tuning pegs to be flattened out. Not a big issue seeing as you'll tune before playing anyway, but obviously not ideal. Also, the front pocket is spacious but there is a gigantic big flap over it which is secured with a metal clasp. This flap has no function at all and is purely cosmetic it seems, and you wonder how much weight could be saved without it.

Not big problems, but worth noting before purchase. Recommended!

Pros: Lightweight and thin sleeve for 4 or 5 string bass. The bass is safe despite the limited thickness of the bag. Big pocket for music and other gear. Comfortable straps. Fits in the overhead locker on almost every passenger aircraft.

Cons: The extra cover over the pocket is not necessary at all, and puts extra weight to the sleeve even though it has no other function than to give the sleeve a fancy look. There is also a hook to attach this cover to the pocket which is difficult to deal with.
The machines of the bass will be brought to the "Zero position" due to the tightness of the sleeve. Prepare to tune up!

Conclusion: Good sleeve. If you travel a lot by air, this is the bag that leaves no discussion with the crew. It fits in the locker - Period.
