The only clothes I have specifically purchased for travel are ExOfficio underwear. That Vneck T you linked is a little deep for me and makes me think of an old SNL skit. The price is right though. The only other specific clothing I use are compression stockings which I wear all the time but a lot of people are interested in for air travel due to leg swelling. Nabee makes comfortable compression socks that are stylish and reasonably priced as far as compression goes. They are synthetic material so dry relatively quickly.
