Osprey  AirPorter LZ Pack Duffel - Medium

Bought the AirPorter Pack Duffel so I could check my backpack when flying. It accommodated my Osprey Ariel 65 backpack with lots of room to spare. Pack was very easy to get into the duffel. But, the shoulder strap is not removable or stowable, so might get entangled in any baggage-handling machinery at the airports. Also, Southwest only accepts baggage of 60 linear inches or less under their free checked baggage policy. This duffel exceeds that by about 2.5 inches and might have cost me $75 to check as "oversize baggage". So I returned it and got the REI Pack Duffel instead. It is 60 linear inches, accommodates my Osprey Ariel 65, and the shoulder strap is removable.

I have had this for 5 years now and I love it ! I always bring this when I travel to put my travel backpack in and it has done a great job protecting my bag (65 liter backpack). It also has extra space so sometimes if I have extra souvenirs on the way home I’m able to use the bag to make extra space. The only downer is the travel strap (which mine is older but it does stow away) really digs into my shoulder and the whole thing is very cumbersome to carry. Maybe having two shoulder straps like a backpack would be better or and extra handle to help manage it.

Over the years, my bag's gotten plenty of scuffs, some snags, and I've lost lots of zippers to baggage handling while flying. I replaced my bag, and decided to try to protect it a little better while flying. I've used this a few times now, and it does it's job perfectly -- my bag comes out pristine on the other side. It can be a little awkward using a single shoulder strap on a heavy pack, but I'd rather deal with that at the airport over having the extra size/weight of another strap when collapsing the duffel and putting it in my pack. As a bonus, there's lot's of extra room. I traveled with a 65L pack, and put in two extra closed foam sleeping pads and 3 1-liter water bottles, and had no issues with space.

My daughter has a big Gregory 80L pack and this held it securely along with her poles and shoes for a flight to Yukon to do some backpacking. Not too hard to carry either, although of course it's always awkward carrying a backpack when it's not on your back.

[This review was collected as part of a promotion.] Honestly, exactly what I was looking for my 65 L atmos bag for airport check in purposes. I'm not a big fan of those big box luggage is so it's nice that there's a bag that's made by Osprey that can protect the entire bag and all the straps and all that stuff. Cool that it can wrap up into a tiny little bag for storage once you're out of the airport. It'd be cool to see a double strap version of this, but this does the job

Does exactly what it says Larger than I expected (wonder if the SMALL would have been ok for my Osprey rucksack) but realise it’s designed for your rucksack and maybe other stuff But since could only find this on-line and time was limited, couldn’t change it

Bought for a flight to Patagonia - was able to hold two empty 55L packs and two lofted sleeping bags with a little room to spare (more if you pack the sleeping bags down). The bag itself doesn't have much structure. Easy to carry and seems durable.

[This review was collected as part of a promotion.] Excellent bag for my 65L backpack. Great for sending through the checked baggage area.

Super easy to use plenty of room to get the backpack in
