UV Permeable Clothing - what do you think?

Hi guys, I've already posted this to reddit and though I'd try here to see if I got any more responses - really want to see whether his is a viable idea so would appreciate any comments :o)

I've got this idea that I've started looking into and I wanted to run it past you guys to see if you think it's a good one. Basically, I work in computing, so don't get much sunlight during my working day; when I'm out and about, the UK climate doesn't regularly accommodate a bare chest so my UV intake is limited. I'd like a running/exercise jacket that is waterproof, breathable and translucent/UV permeable so I can get the most of the sun whilst I'm out in it. I am sure some of you are lucky enough to have decent weather and wouldn't need such clothing, but for the rest of you paleoers, do you think it would be something you'd want? If not a jacket, what about other clothing? Would be interested to hear your thoughts.

Like he said, too cold to go commando. Dan, doubt you will find anything waterproof/breathable. Closest you'll probably find is something like a "tanning shirt". Search for it on the net.

Everyone - I'd be interested **in the same minus the waterproof** as I think that makes the issue much more difficult.

Just go commando, mate. Or at least shirtless.

During the time of year where you'd want to wear a jacket, the amount of UV is minimal and not at the optimal spectrum for D synthesis. For the rest of the year, you'd be better off just not wearing a shirt.

If you're at a really high latitude, supplementation may be necessary at all times of year due to the impracticality of being mostly naked for long periods of time. Best thing to do is choose a desired serum level and test how much you're actually absorbing. Jack Kronk's in sunny San Diego and was laying out mostly naked every day during the summer if I recall correctly and only hit 40-50ng/ml. That may be an argument for lower targets, though.

I used to be a body builder in the 80's, and wore a speedo like swimsuit that was sun permeable, had an insert over the pubic area. It allowed less of a tan line than a regular speedo. I also had several muscle shirts with open weaves, but don't remember what material they were made of....made it much easier to get some sun, while walking the park, fair, etc., and didn't tan so much that you needed sunscreen underneath. Also, kept from getting "farmer's tan" on the arms and head. I think there's definitely a market for a limited line of bathing suits,shorts, and tops, for men and women that are uv permeable, and can be rated for safety..high, meduim, low. After all, when you go the opposite route, like for a fishing shirt that completely blocks the rays, these are rated as well. Something fashionable, that you can wear in public, and not be egregiously outrageous. Thats why I was searching online today--for just such a product....

I do not know of any material that would fit your description for a jacket. You could, nevertheless use UV lamps when you are inside a building, or else if you are tough do gym in the outside with your upper body naked but greased with fat, so that the cold is better tolerated. That was a truly paleo way to get the sunlight, but not so much cold. It might be tough in the UK winter though...

Here lies the inherent problem. you want a fabric that is waterproof but also lets in UV. Typically, the denser the weave, the less UV penetration. (even with white- which is why a very thin white non-stretch polyester shirt is more UV resistant than a long sleeve, thicker white T-shirt, because of weave density) I think you'll be hard pressed to find a fabric that is a dense enough weave to be water and wind proof but loose enough to allow UV to penetrate. You could go with a fabric that isn't woven- that is-sheets of solid material sewn together you might find something waterproof that lets UV through (clear plastic vinyl comes to mind) but that wouldn't be breathable.

Hey guys,

interesting theme for a tennis player ;)

I found a site which sells this kind of shirt for sports: TanMeOn(dot)com

 

Best regards,

Andy

I think this is a brilliant idea. Here in the UK, this summer was just too cold to be shirtless so I didn't get any tan until late September. With a shirt that allowed tanning (and, hopefully, shorts or trousers) any cool but sunny day from March on would be laying the foundations of a tan so in the event of a good summer, being in full sun shirtless wouldn't pose the risks of burning.

I think it is brilliant!

If you find it i'm all for it...not necessarily for those cold winter days and all, but just about every other month would work. Even spring and summer would be fine so that you could get some rays. There are plenty of people who need more exposure, but just can't run around shirtless wearing dazy dukes all day. Good luck getting past the dermatologists though.
