Here are a couple of shots of my Synapse on a recent day hike in the mountains of Northern California. It was my first time hiking with it and it performed very well. It was light, and moved well, even while I was scrambling and jumping from rock to rock. I was very excited to be able to use my 2 liter water bag in the back pocket... though it had to be somewhat underfilled (the drinking tube is visible in the picture). Overall, I couldn't be happier. The synapse has made for an excellent every day bag. I love the compartmentalization that means there is room in the smaller pockets even when the main compartment. and is proving itself as adept on the trail (even for a reasonably long day hike)... and the ability to use a water pouch effectively is great.
The Tristar also proved it's worth this weekend... coming up to Seattle the flight was packed and the overhead bins stuffed. Many folks had to check their carry on bags after getting on. I was told I had to check mine, but I was able to fit it in between two large wheeled space hogs effortlessly. The picture doesn't do justice the poetry and satisfaction of the moment. Though I didn't get a picture of it, the Synapse was nestled comfortable under the seat... it makes a great personal item since it's so easy to find what I want.
