Fine shirt, but you get what you pay for
Perhaps I pulled the trigger too fast. In my haste, I assumed that ordering from Allbirds - where I've gotten several pairs of 100% wool shoes in the past - I'd be getting a shirt of similar makeup. Instead the shirt's about 1/2 wool with a bunch of synthetic material mixed in. It's absolutely fine as a shirt - fits well, comfortable, etc — but it's not the excellence I was hoping for. Then again, I've never found a merino shirt at anything close to this price point, so I probably should've known.
