Love this product. It does exactly what it should and holds up great. Mine still looks like new after a number of flights. The strap is not great for carrying things, but the other duffels suffer the same problem-- and the small strap makes for easy storage. I have seen others with the Osprey one and after one flight there were holes. I would recommend getting this one no matter what brand pack you are putting inside. It fits everything- full pack, large sleeping mat, tent, sleeping bag, and that is pretty full. Love it, get this one.

This bag is gigantic. The matterial is pretty tuff and you can fit almost 1-2 people lying down in it. I like how it zips up nice and small and when using the bag, the zip stash becomes a nice inner pocket. I brought it for my outdoor club and we can fit 4 tents + min it. Great Bag awesome stellar price.

Very simple, no-frills product that does exactly what it is supposed to, which is to go over a backpack to hold everything together for travel. I got XL size which just barely fit my very large external frame REI pack. Note that standard webbing shoulder strap uncomfortable with such weight - padded strap would be beneficial.

After having taken my backpack on airlines before, I was tired of worrying about free floating straps and the loss of items. This duffel accommodated my pack, poles, sleeping bag and tent with plenty of room to spare.

Great bag, tons of extra room inside after you put an already packed bag inside, but very bulky to carry around with a non-padded shoulder strap. Wheels would be ideal. Do not try to carry your pack in this bag if you have a ton of other luggage! It'd be great to use strictly for air travel; put it on at the airport and take it off at the airport, but carrying the bag around is quite a burden! It did hold up well though, and fulfill the purpose I bought it for!

This bag is huge. Not only can you pack all of the kids things for a big trip; you can literaly pack the kids in this bag.
