There are many different leather jacket styles for men that can add a touch of sophistication and ruggedness to any outfit. Some popular styles include:

1. Biker Jackets: These jackets are typically made from thick, heavy-duty leather and feature asymmetrical zippers, studs, or spikes on the lapels, epaulets at the shoulders, and a belted waist.

2. Bomber Jackets: Originally designed for pilots during World War II, bomber jackets have become a classic style with their ribbed cuffs and waistband, front zipper closure, and usually feature two angled pockets on the front.

3. Racer Jackets: Similar to biker jackets but without all the hardware details such as studs or spikes on the lapels.

4. Flight Jackets: Often mistaken for bomber jackets due to their similar design features like ribbing around necks wrists and hips; however flight jackets possess more functional attributes than fashion sense including being made out of thicker materials such as shearling lining which makes them warmer in colder weather conditions.

5. Field Jacket - A modern military-style jacket that is perfect for casual wear because it is both comfortable and stylish with its convenient pockets located at key points throughout its design making it perfectly fit your phone/wallet/keys/etc.

6) Harrington Jacket- Essentially this jacket is an evolution of vintage sportswear often featuring a zippered placket instead of buttons covered by a flap collar which makes this particular style versatile enough to be dressed up or down depending upon your preference.

Each style has unique characteristics that set it apart from others while still providing exceptional quality material combined with timeless appeal so there’s no shortage when choosing one that suits you best!
