I learned about Augusta Active a few months back (I think I did a Yahoo search and they popped up). Over that time I've purchased their wicking t-shirts (to replace other brands I bought a year or so ago) and decided to give their wicking polo a try.
I was pleasantly surprised. I've bought Adidas, Champion, Nike and Puma in the past and they are nice but at nearly twice the price. Augusta Active's shirts are light to the feel, very comfortable (they are true to size), have excellent breathability (I'm the bartender on our golf outings in Texas) and have a sufficient lentgh so they stay tucked in. I liked them so much that I bought them in black, royal blue, white and will buy more red once they are back in stock.
Lastly, I only have one shirt that has been through several washings (the original one I bought for testing) and the collar is still laying flat. The shirt has been washed roughly twelve times and always according to the instructions. I'm not a fan of curling collars and the only shirt that has their collars perfected is Nike Golf (but who wants to pay $50 - $75 a shirt? - well, maybe some folks).
In short, August Active's have become my go to polos for work and play (mate them with their wicking t-shirts to make an unbeatable combo).
