Leno Long Sleeve
I really like this shirt. I agree that it is a little short to be tucked in, and it has a classic look to it. The fit/cut is as expected. I haven't worn it with a pack yet, so I cannot comment on the placement of the seams, but it does appear to be well thought out. I am actually back to buy another one in a different color.

Great all around shirt
I had purchased one Leno shirt and it immediately became my favorite shirt, so I purchased more in different colors. I have worn it in as many environments as you could imagine; from air travel, long distance hikes, multi-day off road trips, teaching tactical weapons classes, and wearing it out for nice dinners. The shirt fits in any situation, if not a bit western/retro. Very athletic fit, a bit short to wear tucked in (at least for me).
