It doesn't hurt that it's currently on sale for $19.99, either, which is the real story - value. You'll have to spring for shipping ($5 for orders <$75), but you can get it delivered to your local Uniqlo for free as well. Made in three colors, my pick is the olive (which I bought), followed by khaki and then the navy. Fit is standard for current Uniqlo standards - a size small fits me (5'11" - 155 lbs, 36-38R and usually a size small/slim medium) like a regular small. You can also see some example fits on Uniqlo's Instagram page, such as this fellow here, who is emerging pensively from his basement:
or here, on this nice young man who appears to be haunted by the ghost of his past and beset by an episode of likely noncardiac chest pain:
But don't miss out on your chance to "hop on board with one of the spring's hottest trends, #UrbanMilitary." ...Christ. Just...just forget that part.
PS - Totally unrelated, but Nordstrom Rack has Iron Rangers in Hawthorne roughout leather (scattered sizing) for $159.97 with free shipping at the moment. Won't stay there long. Here's a link to that. Sizing should be identical to the Beckmans, which run roughly 1/2 size down from your Brannock.
