The men’s solid zip-front sweater provides shoulder, bust, sleeve, armhole and length for eight selectable sizes. A shopper intending to wear it over a shirt needs to check the shirt’s sleeve and upper arm as well as the sweater’s chest. The chart names an armhole measurement but does not say whether that value is a circumference, seam length or flat width.

Follow the unequal changes

S lists 52 cm shoulder, 110 bust, 62 sleeve, 41 armhole and 70 length. At 5XL the values are 66/145/65.5/51.5/77. Across seven size steps, bust gains 35 cm and armhole 10.5 cm while sleeve gains only 3.5 cm. That makes sleeve reach a separate check: moving up for chest room may not add enough cuff length. The chart gives no cuff width or stretch value for the finished sweater.

Use a shirt you already wear

Put on the exact shirt you would layer. Measure its chest and upper-arm circumference, then a zip-front top you can close comfortably over it. Ask for the seller’s finished chest and armhole method in two adjacent sizes and compare like with like. Have the seller measure sleeve from the same shoulder point you used; a dropped or wide shoulder can change where that point falls. A body measurement and a finished garment circumference are not interchangeable.

Check the opening and color choice

The material line states 95% polyester and 5% spandex, without measured stretch recovery. Ask for an open and closed front photo and where the zip ends at the neck. Black, White, Grey and Green are offered; confirm the selected shade and chart row together. This sequence uses the published numbers for layer planning without claiming a temperature rating or tested comfort.
