I don't think I would take this on the road with me, or on an airplane or a very long road trip with lots of other stuff. But for storing the guitar around the house is just fine. It's a little flimsy, but it's a hard shell case and protects it for what I need it for.I bought this for my Guild acoustic to let me carry it on my back without losing the protection that a hard case provides and without having to buy a separate gig bag. It's comfortable, easy to use — exactly what I needed at a reasonable price. I do wish it had a storage pocket so I could carry other things. Also wish it had a hip strap for greater comfort. These additions would make this a perfect dream.the straps squeeze my neck at the top and the buckles don't hold the tension of the fabric well so I always have to readjust, but considering I had noticed that the patent number was stitched into the fabric before I bought it, I figured it was going to be a little crappy. However, it does a pretty good job of reducing strain on the shoulders and back when carrying my guitar, which is why I bought it.Fit my epiphone les paul Jr like a gloveGone are the days when I carry my guitar case with grief. I used to carry it traditionally, with one hand but it's heavy as heck. This backpack mod helps a lot. And it's high quality so it'll last me a while. Now that I've freed up my hands, I can carry more gear.Nice case, love me some Crossrock. Thing is, I ordered a case for an SG, so I had to return it.I have been looking for years for an efficient way to convert any guitar case into a backpack. The Crossrock is superb. It works great on my biggest heaviest Calton fiberglass cases. It is well made and I believe it would fit almost any size hard shell guitar case. You will not be disappointed in this item.Awesome for the price definitely will buy another one for my next guitarSo we'll made I want one for all my guitarsWell made sturdy fit perfect
