Essential travel bags
I LOVE these bags. They are so easy to use and make packing light even easier when traveling. I have used them numerous times on weekend trips in the states and even longer trips to Central and South America. They help to keep everything organized and you can keep your dirty and/or wet items separate from everything else when you're on the move. Highly recommended!

great value!
I bought these for my trip to New Zealand. They helped keep all of my clothes neat, dry and compressed. They have thick plastic and are easy to use. Everyone complimented me on how I packed so light (little did they know I had packed just as much as a normal woman would). The friend that went with me was so impressed with them he went out and bought some right away! I can't speak for other compression bags but you won't be sorry if you buy these!

Great concept and quality
These compression sacks are great. They allow me to compress my clothing and other soft goods when backpacking so they take up minimal space in my pack. They also give my packed clothing an added layer of protection against harsh weather conditions just in case my pack cover fails. I initially purchased the multi pack with the 3 different sizes but later opted for 2 medium sized compression bags. I initially used the small for storing my tent, which worked well enough, and later for my girlfriends clothing - the large was too large for any of my needs, and the medium got used for my clothing. I opted to send back the set because really a traditional style compression sack was better for my tent and fly, and I preferred the medium sized bag to accommodate bulkier cold weather clothing. The bags maintain compression very well and I would highly recommend them to anyone looking for a tool-less way to store soft goods flat. Easy to pack back up when leaving camp.

Great for Travel-Actually Stay Compressed
I've used compression bags in the past, but so many of them don't stay compressed-these really do. They are durable and easy to use, and having three sizes to choose from means that I have a variety of options when it comes time to pack.

packing bags
I have never used an item like this so I can't compare but I must say these really do work well. I was amazed at how much more I was able to pack and having 3 different sized helped me keep organized. It works so well for sweaters and jackets. The little seal slider does slide off sometimes but it slides right back on.
