I find shopping for the guys in my life extremely difficult! Every guy is different but here are my picks for gifts that can work for everyone and anyone, something cozy, techie, useful, a classic, and fun. Up first cozy!
I love my bean slippers. They are cozy, warm, and most importantly durable! Whether for your dad, brother, or significant other slippers are a gift everyone will enjoy and use. 
2) Amazon Echo
I’ll be honest I haven’t felt the need to get one for myself but all the guys in my life who have one are obsessed with it. Perfect for the techie in your life! 
3) RTIC Tumblr
Everyone has use for a good Tumblr. I love RTIC products, they are the same amazing quality of YETI with out the outrageous price tag. Keep your drinks warm or cold all day! A great quality, useful gift. 
A classic! You have the option to engrave them and make it a little extra special for him. Every guy needs a pair of cufflinks that can be used everyday and on a special occasion. 
I think the best gift can be an experience that you share! Tastings or brewery tours can be really fun, I did a Boston City Beer Tour a couple months ago and it was a lot of fun, I discovered new places right in my own backyard. If the guy in your life isn’t into beer there are also distillery tours, winery tours, or whatever alcohol they favor!
