The blue hooded denim jacket labels one measurement “back center length.” That is more precise than a generic jacket-length claim, but it still needs the correct starting point to compare with a jacket already in your wardrobe. Its M–2XL table also gives chest, shoulder and sleeve; use the four measurements together for a planned layer.

Make a four-point reference card

Lay flat a jacket that fits over the shirt or knit you intend to wear. Record its chest, shoulder, sleeve and length down the back centre, writing down exactly where each measurement began. The MAXCT chart lists M as 114 cm chest, 50 cm shoulder, 63 cm sleeve and 62 cm back-center length. At 2XL the figures are 126, 56, 66 and 68 cm. Compare one complete row with your reference rather than choosing 2XL solely for its six additional centimetres of back length: that row also changes shoulder and chest.

The listing says measurements were taken flat with a possible 1–3 cm manual difference, but does not state whether the chest number is the full garment circumference. Confirm that convention before comparing a doubled flat measurement. The hood is named but its depth and opening are not measured, so the chart cannot tell you how it fits over another layer or headwear. The source lists 68% cotton and 32% polyester; it does not provide a weather rating or a tested stretch figure.
