I've ordered a t-shirt from Honest basics a year ago and I loved it so much I'm replacing all my basics to Honest Basics now.
I live in a cold climate and my parents live in a very hot climate. I can wear my t-shirts in cold climate it keeps me warm year around and in hot climate, when I go visit my parents, it keeps me cool. I think good quality cotton makes a huge difference in that case. Also, I love the texture and cut of the shirts as well.
It's the best I could find according to price/quality.
