The SPF in the clothing is fantastic.

Do pay attention though to the washing instructions.
Most will not work if you use fabric softener, so if this is something you normally add to laundry, then you have to wash these separate. No bleach either. I think just the washing separate is all you really need to pay attention to, wash and hang to dry they last a fair length of time.
I have a white long sleeve one, that got some oil on it when we were on our way to Nelson. My bike broke down and I guess I somehow got oil on it. It will never be clean again, so a $50 T-shirt I only wore a few times.

Brett pointed out to me, and since he did I've noticed that you can get a lot of the underarmor items that wick away moisture so you stay real nice and dry and sweet smelling. These if you watch for them sometimes go on sale for around $20. Heck that is cheaper than a cotton t-shirt from any HD shop.
Now that I know more about the products, I really look for clothing with SPF in it. If they also have vents, or ways to roll up sleeves or leggings I like this too.
You already have the cool vest for keeping you cool, just a couple shirts and you can even get pants with it in too.
They feel much lighter and cooler than other materials.
