When I travel I typically pack in a large backpack so that I can carry all of my stuff on my back and not have to deal with awkwardly trying to roll a suitcase around an airport and through cities and up stairs, etc. And carrying a duffel bag can be rough on one shoulder. The only downside to my backpack method is that on weeklong trips and when I don't pack as light as I should - I find that my shoulders get sore. So with a two week trip planned for the fall, a trip without definitive places to stay every night that might require carrying the bag all day on most days, I decided it was time to find a backpack style travel bag with a waist belt to help carry some of the weight. After doing a lot of research I finally found this Osprey bag. The Farpoint is everything I was searching for and more, the backpack straps can be hidden (zipped up to act like a duffel when flying to avoid the straps getting caught on things), the daypack that can zip off of the front to act as its own bag -- this is a handy feature both for flying when checking a bag, and for leaving stuff at a hotel and still having a bag ready to go for the day. And most importantly it fits my petite frame. I got the S/M size and it is great for me at 5'2". And because we are dorks and my husband was jealous of my bag he was able to get the same one (in a different color) in the M/L and that size works for his 5'10" body.
And when you think about the fact that you are getting two bags from a trusted company like Osprey the price really isn't all that much.
If you are looking for a do it all travel bag this is it!
