I will add another data point to this: Unbound Merino tshirts※¹.
As other replies have mentioned, merino is definitely fragile (both of mine had holes within a few months). But the caveat being that I literally wear them every 2nd day (I own two day-use tshirts (2 more for night/spare) and rotate them daily, so they probably got 5 years of use in the year that I've owned them.
They are even more amazing for anti-smelling than synthetics with silver woven into them (like Lululemon Silverescent). They can go for weeks without washing (I've tested with other people's noses). Caveat being if you spill something on them or absorb a ton of barbecue smoke, they will need a wash (or at least spot cleaning).
I think merino tshirts (2 pair), lightweight synthetic everything else, powerful phones or ultralight laptops + USB-C has enabled folks like me to travel indefinitely (except in winter) with a 20-25L bag or less ※².
