The Good:
I bought this for a recent trip to Florida and once I got the right size, I LOVED it.  It is very lightweight, breathable and provided great sun protection.  My final purchase was a medium, black.  I've washed it once and it seems to be very durable with no fading.

The Bad:
I originally ordered a large because I am 5'10 and a size 12.  This thing was HUGE - as in, I could fit two of me in it.  I ordered the item well in advance of my trip and received the too large, large about a week before.  I contacted Coolibar directly to see if I could get an exchange for a medium in time for the trip.  The sales rep told me I would both have to pay for the return shipping and pay to have a medium sent two day air.  This seemed ridiculous to me given that I followed their measurements in ordering a size and the item was shipped for free.  The rep offered to leave a message with their customer service as I called after their customer service was closed.  I agreed.

I was contacted by customer service the next day and they agreed to get the new item to me in time for the trip at no extra charge.  And they did.  Although, I had to buy the new medium and then send back the large as a return, not exchange, waiting for a refund on the original purchase and footing the bill for the return shipping.

Bye the way, the medium is still VERY roomy on me.  I asked the customer service rep if Coolibar sizes ran large and she would only concede that they were "generous."

I realize more and more companies are not paying for the return shipping and this is a risk with online shopping.  However, when the return is clearly the fault of the company, I really don't think I should have to pay for it.

The Bottom Line:
I'm giving three stars because -
- I liked the product
- Would try them in the future, especially on sale items where an exact fit is not an issue
- Products are pricey and return shipping is on you if items don't work out
- Customer service is a mixed bag: initial rep not that helpful, follow up customer service call was prompt and there was an attempt to resolve the situation, and the new item was rushed to me in time for my trip
