I've been very happy with my Exos 58 that I got more than a year ago. Its comfortable and light, and can hold all my gear.
Recently, I had been noticing that one of two things was happening. Either my pack was getting bigger, or my kit was getting smaller. I figured it was the latter of the two.
So, I decided it was time to look for a smaller pack. I opted for a Talon 44 which I got yesterday. I packed up my 3-season kit with two days worth of food and a bit of water. Everything fit very nicely, with just a bit of room left so I could do a week-long or winter trip.
Here's the point where I was certain I had done the right thing in getting a smaller pack: I opened up my Exos 58, and almost literally dropped my fully loaded Talon 44 right inside. With room to spare.
As soon as I can be certain that the Talon will be comfortable to hike long distances in, my Exos will be up on gear swap.
