Thought I would put this up after several uses as a specialist hot weather shirt:
http://www.bcf.com.au/Product/Columbia- ... rom=571697I have used this shirt in temps around 16-33C for a couple of hundred ks now, walking in full sun, WITHOUT sunscreen and it is very good. I tested it first by putting my (clean) mouth to the inside of the shirt and breathing/blowing through it easily. I think this is as porous as you could get and remain (as I have) completely unburnt underneath.
This shirt, NOT the
other Columbia fishing shirts was the pick. By far the easiest movement of air!
It has no mesh under the arms which is what I wanted. Mesh at upper back inside though. The material is very tough and so light. Fantastically cooling as far as that goes in the sun. I walk with the sleeves down and unbuttoned when the sun is low, no Sunscreen on hands or arms. I bought it on sale for about $60.
As you would expect dries while you are looking at it. I have a favourite POLY/Cotton shirt from the opp shop which is as "breathable" and sun protective, dries as quick, has press studs (Miller shirt style for the oldies!) pretty spiffy looking cost me .99cents.I wear this with the airism mesh Tshirt I mentioned above.
I wanted a changeover, (got the light grey) so after much checking I went with this.
Given the hot weather is not finished this could be as great for you as it has been for me. It may swim on you, so best to try it on. I got a medium and it is a very roomy medium, the large, for reference, for me would have been equivalent to XL.
I don't work for BCF and I paid with a members card which I got when I bought it.
Summing up ; ultra porous, completely sun blocking (3 hours max time in sun so far-NO SScreen) weighs nothing,dries in a wink.
If they lower the price I would buy another tomorrow.
Cheers.
