CQR has rapidly become one of my favorite brands of clothes. I've been wearing their tactical pants for years and aside from a defective snap they've yet to let me down. Seeing they now have shirts of similar style and material I was eager to give them a try. As I always have more need for more pockets and places to clip things. But shirts I've ordered from Tesla in the past have tended to run small, VERY small. So I ordered only one (in coyote color), having learned long ago not to trust sizing even in stores, much less online. I've bought enough different brand clothes to know the whole "true to size" notation near the top of the page can not be believed. Anybody who's ever purchased jeans knows you can't always even trust sizing from the same brand. Fortunately, in this case, it couldn't have been more true to the usual size work shirt I wear from most brands. Fantastic! Wore it. Washed it. Wore it again. No shrinkage. So I was off to order more.Sadly, after waiting nearly two weeks for prime delivery on the first shirt, they were already sold out of all but one other color in my size: large. It was at least the color I wanted most (navy), but I'd have really liked one in dark green too, which green had completely disappeared from the listing page, giving hope that they might have far more colors back in stock at a later date, like with their tactical pants. As with their pants, if anything the one pet peeve I have with CQR is that they never seem to be able to keep anything in stock.LOVE the shirts. They're a bit stiff at first, but I'm sure they'll loosen up like their pants do, after a handful of washings. They loosen up some after just the first washing. I also have seen no indication of fading after only a couple washings. Despite the material being a 65/35 poly/cotton blend, holding this shirt up to the light, it appeared just as breathable as my usual 100 % cotton work-shirts, albeit less flexible. All the anchor points are awesome. They work great for readers or sunglasses and similarly lightweight accessories. I wouldn't trust hooking up something heavier, like any kind of tool though. I frequently clip an angular LED work light to my shirt. And I'm sure the small loops would tear through quickly, after taking it on and off several times per day. Fortunately, the pockets also have convenient pencil openings at the top, which is great.If there's any room for improvement - aside from increased color selection and offering a supply that isn't so frequently out of stock - and I only point this out because, to their credit, CQR has been known to improve their products based on customer feedback in the past - I'd question why they didn't use mesh against your skin behind the front hidden pockets, like similar shirts do for greater breath-ability. They use mesh under the back flap, but there's nothing in front to allow air through, other than the gaps between the button down opening. I'm not really sure I see much purpose in having a pocket under a pocket like that in the first place. It's nice to have options, but the side opening is definitely less practical and it seems that using both at the same time would be too bulky, especially over one's chest, even more so, considering neither is pleaded. So, it would seem to make more sense if the "hidden" pocket at least doubled for ventilation, which would likely be it's primary goal. But, I've never studied the mechanics of clothing. So maybe they know something I don't. Maybe such would weaken the integrity of the front. Maybe it's more effective to trap some moisture for cooling. Or maybe it would increase the price disproportionately. Then again, their short-sleeve equivalent of this shirt also has a tie strap on the sleeve, which seems pretty pointless... On that note, I'd also like to see a couple additional holes in the tie strap for those who want to tie up the sleeves mid bicep, rather than just above the elbow.The only other thing I'd mention is that despite it being the same basic material and brand, the colors are not consistent with CQRs line of tactical pants, at least not the ones I've purchased less than a year ago. Regardless, I'd definitely buy these again, at least at this price. Easily one of the best budget brands of clothes I've come across. Good function and performance.
