Built with the proprietary Lederman Optical Array (LOA) to reproduce the true stereoscopic depth of field of human sight, 3D Astronomy 's 8x42 Space Walker 3D Binocular yields views of the night sky that normal binoculars cannot offer. The LOA duplicates the physiological process that allows humans to see with depth perception and eliminates the flat depth of field common when viewing through binoculars focused at infinity. The LOA is complemented by phase-corrected and dielectric coated BAK4 roof prisms and fully multi-coated optics that work together to improve light transmission throughout the optical path, reduce internal light scattering, and increase color rendition, image clarity, and overall contrast. Rounding out the optical performance is a wide angle of view, long eye relief, and comfortable exit pupil. A pair of removable angled eyecups is provided to block peripheral light and eliminate ambient light interference with your viewing experience.

No bleed through of t-shirt color beneath. Very hard to achieve, but Alimens does it.
Size: X-Large, Color: All White
At the price point of this shirt, i'm super impressed with the overall quality, fit and appearance. I have had short sleeve white from others in the past and what sets this apart from them is this ... this needs no t-shirt underneath. if you did choose to add a t-shirt, the t-shirt color will not bleed through the white optics. I am daily shirt and tie guy, who loves button downs. I own many VH brand shirts and this Oxford is sized exactly as a VH. Will be ordering more!!

Good fit, crisp, washed well.
Size: Large, Color: Burgundy
This is the perfect short-sleeved version of their dressier long-sleeve Oxford button-down. Fits my newly downsized, 160-pound, 5'9" shape just right. (At 170, this might be too snug, if I put the full extra ten in my belly, which is where it always seems to go.) For appearance's sake, I prefer the long-sleeve and just roll it up on a hot day. But, sometimes, you really want the airiness and height of a genuine short-sleeve shirt. If you're OCD about a consistent look (which, sometimes, I am), and you like their long-sleeve version, having a few of these in your closet makes life easy on a hot day.

Great shirt but won’t work if your slim cut.
Size: Large, Color: Dull Pink
Fabric is nice and looks of good quality, just is a bit wide in the torso, so it doesn’t fit my slim fit husband. If you wear slim fit dress shirts I would likely say this shirt will be boxy on you in the waste. Good price if it works for you and comes in so many color options!

No negatives about these shirts.
Size: XX-Large, Color: Light Green
Can't say enough good things about these shirts. I have purchased several colors of these shirts and they fit wonderfully. I have a belly so button down shirts that actually fit are hard to find. They are either too big across the shoulders to fit my belly or just too tight around my belly. These fit and look create and i will buy them again as needed.
