Summary:
Shirts like this are worth the investment, provided you care for them properly and minimize your loadout when traveling to fully take advantage of their properties. In this regard, this is the best shirt I've tried so far (among ~20 merino wool/blend shirts). However, the two added travel features are unnecessary and could actually be a hindrance, depending on how you use them. I plan on buying another W&P tee, but I'll just get the regular 78/22 next time and save $30.
The good:
This is perhaps the most comfortable merino wool garment I own, and where many others tend to feel scratchy (even ones that market themselves as "soft"), this one hasn't bothered me at all yet. The fit is great on me, and I have a fairly athletic build on a short-ish torso (5'8", 175 lbs). I don't feel like it's too long on me, but it is just slightly longer than most cotton shirts I own. One thing I absolutely love is that the neck isn't super loose, like almost every other merino wool brand I've tried tends to be. This is maybe the most important thing for me, as I don't want my chest/back exposed when I'm traveling (hairy men will likely understand). The shirt feels like it could take a beating, and I've had big dogs scratch my chest jumping on it and the shirt still looks unblemished. The heather grey is a phenomenal staple color, and I wish they had more heather options available. I've worn the shirt five days in a row with no washing or other care (aside from folding it up and sitting it on my dresser overnight), and it never smelled at all.
The bad:
I honestly only bought the travel tee because the neck opening looked tighter than the regular tee. The two added features (the hip pocket and the built-in mesh roll pouch) seem mostly useless to me, even as a frequent traveler. Firstly, the pocket is very small, and on the grey shirt it's quite noticeable (since the zipper is black). Therefore, I'm not sure what you'd put in this that you couldn't put in a wallet/fanny pack. Also, unless you're accustomed to having a pocket here, you're also very likely to forget that you put something there and accidentally wash it. Given that spare money might be the most common item to place there, accidental washing isn't ideal. The other feature, the neck roll pouch, is also not very useful because, as others have mentioned, the way that you have to roll it up makes me concerned that it'll eventually warp the neck. Keeping shirts rolled isn't a big enough issue to warrant such a feature, especially at a $30(!) premium.
