worth the investment
It does its job like it says it does. A great way to extend the life of your expensive osprey bag.

good idea!
Giant packs and airport luggage check-in procedures don't always get along. The security and check-in folks always want us to "contain" or "secure" the straps and other lanyards, bungees, etc. Puttin' tape around your pack seems to leave that excellent sticky residue for grass and dirt to stick to when you reach your final destination. I think if you and your pack commute alot, spend the $30 or so and get you this piece of convenience. So far mine has doubled as an extra duffle bag, temporary cover for boots and clothes when the bivy sack won't provide extra storage on damp and frost covered nights. It also, if your concerned about weight in your pack, can serve as a fairly descent makeshift pillow. Get creative and enjoy! P.S....Dont forget that it fits almost any size pack (mine is a xl crescent 90) and many different brands.

As Advertised.
The Osprey Airport LZ is a great addition to any travelers luggage armamentarium. It keeps the packs with straps safe from snags and conveyers. It is big enough to hold a couple of any bag that you can throw into it. It comes with a strap so you can throw it over your shoulder but I found the strap is too thin for larger luggage and it doesn't cinch up, other than that. Great buy.

Osprey Packs: Airport LZ Luggage A+
Kept the pack safe at the airport. Plenty of room for a large extended pack.

Great investment
I love this bag.I stuffed two backpacks a sleeping pad,bivy tent and a sleeping bag,in it.I've used it bag twice already(4 flights) and it held up just fine.A little warning though.Be careful how much you put in this bag.I was charged an extra 40 dollars on one flight for excess weight.I would also recommend the Osprey rain cover.
