These are some signs to look for when looking for a high-quality mens denim jacket:

First of all, look for a jacket made of 100% cotton. High-quality jackets are usually made from pure cotton. Avoid too much stretch (like polyester or elastane mixes), as it wears out faster. Next, weight matters, so look for midweight (11 to 13 oz) or heavyweight (14 to 16 oz) denim for the best structure and durability. Then, check the seams and also stitches. Next, check for metal buttons (like copper or brass) that are firmly attached. A premium jacket will feel sturdy, hold its shape well, and last for many years.
