Description

BOX Three Prime 9 Shifter - 9-Speed, Single Shift, Matte BlackThe Box Three shifter combines performance and value at an affordable price point. It makes good use of nylon composites in both top and bottom shells as well as the levers. Not only is the shifter mechanism joyfully simplified, but fewer shifts are needed for every mile of travel. Prime 9 is also terribly forgiving so you won't have to constantly adjust your set up. Prime 9 technology offers the same range as a 12 speed drivetrain, with fewer gears

Great Fit for Tall Men — Comfortable and Stylish
Size: 18.5" Neck 35"-36" Sleeve, Color: Cameo Blue
I bought the Van Heusen Men’s Tall FIT Dress Shirts in Poplin because it’s hard to find dress shirts that fit well for taller men. The fit is excellent — long enough in the sleeves and body, yet still tailored and comfortable. I especially like the blue color, which looks sharp and professional. I have already purchased multiple shirts and would definitely buy more. Very happy with these. Key Features: Tall fit designed for men with longer torsos and sleeves Classic poplin fabric for a smooth, crisp look Long sleeves with button cuffs Traditional button-down front Easy-care fabric, machine washable Available in multiple colors for versatility Modern, tailored fit that isn’t too loose Disclaimer: This review reflects my personal experience only and is not professional fashion or sizing advice. Individual fit and comfort may vary.

22" neck With good length sleeve relaxed and bent
Size: 22" Neck 37"-38" Sleeve, Color: Flame
22" neck With good length sleeve relaxed that didn't walk up forearm when arm was bent. For a fitted shirt. 22" neck was true to size but the waist is still quite large. Even with creative folding it was noticeably large waisted. Fabric is high quality and vivid color that should last. Price is Fair and a good value for this shirt. Buttons fit easily into the holes but are secure and won't come out too easily.

Good fit and fabric quality, and the button color doesn't stick out too much.
Size: 17" Neck 35"-36" Sleeve, Color: Black
Unlike some competitor shirts, the buttons in these are not BRIGHT white. (Subtle buttons are better for my usee.) Fit and fabric quality are both very good.
