This is hands down the best hiking t-shirt I own. I have now done 3 multi day hikes wearing this non stop and it never smells. Even after wearing almost 5 days straight on the Jatbula trail it did not smell. It’s comfy, moisture wicking, loose fitting and versatile. I’m a small girly but bought the size M because I wanted it to be a bit roomier and it’s the perfect fit. I recommend this to all my friends - love love love!
