I have been traveling, currently still in Europe, for 4 months with these bags. They are awesome! I did not know what to expect when getting them because I did not want something that would rip, burst, or tear and these have been through a lot. I can fit 2 pairs of jeans plus some other leggings in the Large bag no problem and it stays airtight for days! I have another brand of spacebags the Samsonite Space Saver Bags and they are good for smaller items but if you have heavy clothing or a large quantity then these Eagle Creek ones are for you. At first I felt like I needed to be gentle with these bags, both brands, but I find that I can throw these around so to speak more than the Samsonite ones. These are durable bags. If I am able I will post a picture of my suit case, these save SO much room. Anyone traveling for any amount of time will love these! I will never pack without them again. Just don't loose all the yellow bag closers, I have one left lol oops.
