I have used the calpak once so far and plan in using it for a trip to Europe. I like it except the zipper on the carry-on part does not go all the way around, so it is hard to keep it open. The back pack zips on and off easily. Similarly, the zipper on the backpack is short, going around only half the way making access more difficult. The whole unit is slightly smaller than expected with room being taken to accommodate for straps and handles. I like the padded small handles and the wheels are big and sturdy.

Bought this for my teen son and it is perfect. We were able to easily fit plenty of winter clothes for a four-day trip inside - including scarves, gloves, etc. and toiletries. So - although it is small enough to carry on a plane, it is very roomy and the wheels/handle/shoulder straps take up very little room. ............ One complaint - the blue is NOT a royal blue as pictured. It is a very VERY dark Navy. I would extrapolate from that observation that the red is probably maroon and the green is probably forest green. ............. This is very well made - Much better than the Samsonite luggage I've always purchased. The zippers are extremely heavy duty, sewn in very well. Overall, I'm just very impressed. ............. This was such a great deal off of list price and I liked the backpack on the front. Son was able to pack it full of snacks, games, etc for a 14 hour bus trip - backpack was smaller than I expected, being accustomed to full-sized school backpacks, but it is plenty for packing stuff to do on a trip. ........... I would definitely purchase this luggage again and look forward to swiping it from my son for MY next trip! :-)

These suitcases appear to be very nice. I bought them for my grandsons, 7 and 9, a trip to Denver this summer. Thought the backpacks would be great for use on the plane and once we arrive in Denver to use out and about. The only issue is that the blue is definately navy and not the bright blue pictured. Not really a problem for me.

Bought these before a marathon Megabus trip with two changes of busses each way. Bags held up to the handling of the employees. Toted them all over Manhattan and I had to note they were MUCH quieter rolling than MY less-expensive wheeled backpack. We had them CRAMMED FULL even using a space bag to stuff a sleeping bag in each one along w/ a week's worth of clothing and the zippers held up. Wondering if it is possible to buy replacement backpacks if something happens to the ones that came with the piece. My only complaint is that one of the snug-straps that fastens to the backpack on each bag does not "lock" when tightened, so had to tie the webbing in a simple knot to keep it from slipping. That side of the buckle is not made to lock tight when snugged up. I thought that was weird, since, w/ out the backpack on, these straps can be snugged up to take the strain off the zipper like luggage straps. But all in all after a 6 day trip w/ a lot of Megabus riding and transfers and hoofing it all over Manhattan, they still look good and work fine!

This is the perfect carry-on for flying. Fits perfectly in the overhead storage compartment. Handle is very sturdy and wheels work great. Backpack can be unzipped to create 2 separate pieces. Several compartments and most of them are zipped. Very sturdy. Very well made. I'm extremely happy with this purchase.

This luggage is superb. I traveled for three months with everything i ever needed packed wonderfully into this bag. Plus for short trips I was able to detach the duffle and just take what I needed. It had extra pockets on the outside that were fantastic to pack toiletries without mixing them in with my clothes. Many people asked me about this bag and admired it. It is just great and I am taking it on my next trip in 2012.
