I own better quality travel cubes, but couldn't find them and needed to order quickly off amazon. These are fine, but they are not finished well on the inside and have loose nylon threads from the fabric fraying that get caught in zipper. I used 2 for a 44L backpack as a carry on to Europe. Ideally I would probably go with one this size and 2 smaller ones. They do allow you to stuff and compress your clothes and then just take the cube out and put in a drawer to unpack. I worried that stuffing too much would cause a seam to open since the fabric frayed and I didn't want to risk that while gone for 3 weeks. I would pay more buy osprey or eagle creek cubes if you plan on using these often.
