Whether a shirt from Smartweave would have overcome that level of saturation I don't know, but I've worn the sample they sent twice on hot days and it seems pretty effective. No patches, but I was definitely perspiring like a whatsit underneath. It would have added to my confidence in any meetings I attended whilst wearing one.
Don't get me wrong; you'll still niff a bit. Some journalists in the Nationals used the shirts in the gym or on long cycle rides to test them and I wouldn't advise that - but for ordinary use, keeping yourself comfortable and dry, the shirt seemed about perfect.
There's a good selection of shirts on the site with variations in collars, fits and cuffs; illustrated is a relatively casual white jobbie with a tartan trim, I have the grey with black trim and it looks very good indeed. If you want to go formal for work shirts you can do so, without the trim and double cuffs for cufflinks are available. I did a little mystery shop and asked the difference between tailored and slim fit, not telling them I was writing about their company, and had a thorough response within an hour, which bodes well for customer service. Also the shirts are well put together; the fit is good on me and the seams appear strong.
I'm not short of shirts, if I'm honest; if I were I'd certainly be looking at spending around £75 a garment from these guys.
Best thing: Appears to work, sweat wicked away as promised, but looks and feels like an ordinary cotton shirt. Companies attempting this sort of thing before have produced odd-feeling and odd-looking garments but not this time.
Worst thing: Remembering not to use conditioner in the wash, which interrupts the drying technology. You can always wash it again, conditioner-free, and its de-sweating properties will be restored, but I'm a swine for forgetting and sticking it in with the rest of the whites.
