Really it's all about you and your best man's style. Some of the best groomsmen gift ideas are personalized beer glasses, whiskey gifts, wine gifts, hats, etc. If you're looking for gifts in the $20-$40 range then consider a personalized glassware or a hat. Finally, if you're in the $100+ price range we would suggest moving up to personalized whiskey glass and decanter set. They come in many styles, and even the most discerning groomsman young or old is sure to appreciate the fine quality and workmanship.
If you're still unsure, we recommend keeping it simple with classic gifts that never go out of style! Choose items that your groomsmen will genuinely enjoy, whether it's something they can have fun with or proudly show off to their friends. Make it personal by engraving their names, adding a unique touch that will remind them of you and your special day every time they use it. A thoughtful, personalized gift will make the memory last long after the wedding.
