I'm about 6'5" and 245 lb; I normally wear a 38" or 40" waist (hoping to shave that down a little - 'tis the season for resolutions, right?) and 36" inseam in pants and an XL-Tall in shirts works great. I've spent enough time dealing with clothes that don't fit to be willing to just do without now, no matter how cool the item in question is - if it isn't the right size I don't want it.
That said, I recently got a pair of the one style of Outlier pants in my size, and I'm really enjoying them - other than they tend to get a little static-clingy in the dry indoor winter climate, and I'm not a big fan of the whole skinny-leg thing. I LOVE how wind-proof they are - and I'm in Minnesota, so the reviews I saw that claimed they tended to be warm were music to my ears. In checking out the other brands recommended here I found that Bluffworks also makes pants in my size, and ordered a pair from them, as well. I should have them next week. After whining so loudly about so many companies NOT offering tall sizes I almost feel obligated to show support for the few that DO.
Back when they still offered 36" inseams I had two pair of Scott E-Vest 'hidden cargo' pants and just loved them; wore them alternately almost daily for years until I pretty much wore them out; would buy another pair if I could. My only issue was that the magnetic pocket closure snaps would erase hotel mag-stripe door cards in one pass; I had to palm the keys deep into the pocket with my hand between the card and the magnet as it went through the opening. Never had an issue with credit cards, though.
Unfortunately I have yet to have found a Tall sized Merino wool shirt (other than the one style of Minus33, which is more like a base thermal layer than a shirt to be worn on its own) - but I'm still looking. Surely if Merino is truly that fantastic it'll catch on and SOMEONE will start making them in a wider range of sizes.
I can definitely vouch for the amazing stench of nylon - I got a free running shirt for participating in a 5k race. It's light, breaths really well, doesn't get wet - etc - but after two hours of volleyball it stinks so bad I'm embarrassed to sit in a bar for a post-game beer. I normally wear cheap cotton t-shirts, and I won't claim to be fresh after sweating in them for a couple hours, but christ - that was just gross.
I'll report back on the Tom Bihn TriStar bag. I've been using a 'Synapse' back pack for about 26 months for work - it's been fantastic, and I expect the TriStar to be every bit as awesome.
I believe 'one-bag' travel is only partly about the bag; the real secret is to be confident enough in the limited gear you bring to be able to leave everything else behind, then get the bag necessary to tote what remains. It's partly mental - knowing what to expect, partly gear - having a few key items you know you can count on even if things don't go as expected, and the bag just ties it all together.
I can't imagine anyone complaining about this thread going totally off topic; it isn't like there has been much to discuss ON topic that hasn't already been run straight into the ground - 10x over.
