I've been a long time supporter of Osprey and have traveled the world using my Talon 44. I love my Talon for how light weight the pack is and the 44 liters forces me to pack only what I honestly need for my entire trip. I don't like checking bags when flying, save for possibly on the return trip when I want to lighten my load of all the treasures I found along the way. With my old set up for air travel I had collapsible bags for 2 things, the day pack backpack and and a duffel for that return checked bag I mentioned. I also take a collapsible water bottle that worked really well as long as you are in an area where you can refill. There were 2 main reasons why I "upgraded" to this Farpoint 55 set up for air travel, the luggage style opening to load (versus the top load of my Talon) and the added day pack that snaps in. I have always used the front bag across my chest for my important personal items and having a way to lock that in will be great since when you are really moving and shaking through an area the shoulder straps tend to slide down (I'm not too broad shouldered). To hit on the luggage style loading, that's a huge plus. Trying to rummage through a top load bag a few times a day becomes a repack everyday if you are traveling to new locations a lot. The luggage style allows you to see everything without needing to move everything. The ability to put the straps away is great. There has been a few times on smaller flights that I had to check my Talon 44. I had it down to a science on how to tie all the straps together to help protect them on the belts. However, I have and a plastic clip snap off and I am assuming it was caught in a belt somewhere along the way.If you have never owned an Osprey, they offer the most amazing warranty. If something rips, tears, breaks...they fix it for free. If they cannot fix it they replace it at no cost to you. That goes with all of their packs no matter the size or how old they are.If you are considering the Ozone Duplex or Porter lines (the 2 air travel ultra light options that generally get mentioned in the same conversation as the Farpoint line) : Make sure you try them on before you commit to them. Make sure you add weight to them to see where the pack sits. Consider where you will be walking, is it going to be hilly, a lot of stairs, only airport to hotel or air bnb, walking miles...my friends and I feel the Ozone Duplex and the Porter doesn't sit well with weight. They are wider versus longer and the middle back takes on a lot more stress than the Farpoint. The Farpoint is just enough longer to distribute the weight much more evenly across the shoulders, mid back and lower back areas. I felt a bit more tipsy with the wider packs and for walking stairs or any hilly areas that would become a bit of an issue.Now to the few things I wish Osprey would consider adding to the Farpoint to make it even better: The day pack is really great with the soft micro fleece material liner for your electronic protection. The bag has enough space for a day carry. However, I want more dedicated loops to add carabiners. I want to clip on things I do not want to stop and open my bag for, especially if I am on a hike. I want a few loops on the back and on the shoulder straps. The 2 water bottle holders are a bit annoying as to where they are placed all the way on the back of the bag. I cannot easily get to them without removing my pack. I know the older model of the Farpoint 55 had a earphone hole at the top of the bag that people would hijack for a makeshift water bladder hose. Why isn't there a thin waterproof section for a water bladder and a hole at the top for the hose? Most of the people buying this set up travel light and do outdoor activities while traveling no matter if they are going for business or pleasure. Osprey being a trekking company has missed on this day pack in a few big yet easy fix ways.I have the same request for the 40 liter portion of the bag, give us more carry loops. Sure I can use the straps, but now I'm putting more pressure on parts that were not specifically designed to be carry loops. There are 4 dedicated loop locations on the back, give us a couple on the front and a few small zipper sections on the hip pads for little things like gum, chap stick, a few bucks...The only other wish is that there were more choices in color. I love my citron yellow Talon because it is easy to see in a crowd. Red and especially black are 2 colors that are so common that if you do check your bag that it could be a bit more work seeing yours versus all the other bags. I will put a few specific colored locks or carabiners on the bag to make mine stand out.
