The 15 best stocking stuffers for men under $20

The best gift you can give the people you love most? The guarantee that they'll have clean drinking water, whether they're hitting the trails, camping in the mountains or jet-setting to other countries. Here's the deal: They probably won't pull it out on the day-to-day, but when they run into anything questionable, they'll be glad to have this portable water filter within reach. Just stick the straw in any body of water — no matter how murky — and it'll remove sand, silt, cloudiness and unwanted germs as they sip. 

It's on sale for $10 this Prime Day, making it the lowest price we've seen all year. Peace of mind is priceless, don't ya think?

The hottest, sweatiest days of the year are behind us, but they'll be back (with a vengeance) in a few months' time. When the warm weather starts to get the best of him, he'll be glad to have this towel for some relief — just soak it under water for 10 seconds, wring it out and wrap it around your neck for a long-lasting cool. 

I know, I know, socks are a pretty basic (read: boring) Father's Day gift, but trust me, this pair will really putt a smile on Dad's face. They tell an all-too-familiar story of bogeys and blunders — which, let's face it, is a typical day on the green. 

AirTags are a pretty spendy stocking stuffer, so here's my suggestion: Wrap up a four-pack and stick it under the tree, then stick a couple of these holders in his stocking. That way, he can clip 'em onto his keys, backpack or dog's leash for easy tracking. 

The next time his tire pressure light comes on, he can power up this compact gauge to find out just how low he's riding. It measures tire pressure in .1 increments to ensure accuracy, with one five-star fan writing that "this gauge was identical to the reading that the technician told me." The screen even lights up, so he can easily read it in the dark. 

Does he spend a lot of time on his feet? Physical therapists swear by this reflexology roller for anyone dealing with sharp, shooting pains as a result of plantar fasciitis, poor shoe support or hours of standing. One reviewer dubbed it a "miracle worker," writing that it "reduced the swelling in my ankles and feet at the end of my work day." Another exclaimed: "I've tried everything: different shoes, inserts, PT, everything! It normally takes hours for the sharp pain to go away, but this thing? Rolled my foot over it a couple times and the pain disappeared. "

Help him keep his pride and joy (ahem, his car) pristine. Press this slimy gel into air vents, cupholders and other hard-to-clean spots, then pull it away slowly to remove dust and debris.

Nature's beauty takes center stage in this delightful deck. There's a different watercolor of a National Park on every card, from the awe-inspiring Grand Canyon to the swampy Everglades. 

I'm not going to get into the specifics, but our phones are a breeding ground for germs. This compact cleaner gets rid of all the bad stuff — bacteria, questionable gunk and oily fingerprints — with its 2-in-1 system. First, spray the whole phone with the cleaning solution (it comes with some, but she'll have to replenish it), then wipe it down with the microfiber cloth. 

Now, here's a stocking stuffer that'll help him up his golf game. This little tool cleans and sharpens the grooves of all kinds of golf clubs — drivers, fairways, irons, wedges, you name it. "I'm sure there are much more expensive versions of this out there, but this really has fit the bill for maintaining my old wedges," one golfer glowed. "For a low price, you can have a necessary and useful tool to give your irons and wedges some new-life feel." 

He may not think himself a sneakerhead, but he'll be pleased to see these dual-sided sponges make his oldest, dirtiest kicks look like new. Think of them as Magic Erasers but designed specifically to remove scuffs, dirt and other marks from white soles. "Even my grossest pair of sneakers that I use for Frisbee golf in the mud came out much, much brighter than they ever have from throwing in the washing machine and cleaning with a toothbrush," one satisfied shopper wrote, adding that the key is to "keep the sponge moist and use a vigorous but very light buffing motion" 

Now your around-the-house handyman can pick up screws, nuts, bolts or whatever else he drops on the job. More than 20,000 Amazon shoppers snagged one of these in the last month alone, with one writing that it's a "very useful gadget for engineers or those who like to tinker with fixing things." 

Is he slowly (but surely) building out his smart home? Then throw this pack of plugs into his stocking, so he can power up (or down) lights or appliances without actually, ya know, flipping a switch. Control whatever's plugged in in all kinds of ways — set a schedule or timer; sync it to Alexa or a Google Home Device or do it manually via the Kasa app. Senior Tech Writer Rick Broida says these bestsellers "have never given me a lick of trouble," which is saying something since he's tried just about every brand on the market. 

As long as he has this on, he'll always have nails, screws and drill bits within arm's reach (actually, even closer than arm's reach, when you think about it!). Thousands of Amazon shoppers say it's a must in any toolbox, including one reviewer who bought it for her husband and raved that it "saves him trips back and forth and he doesn't have to worry about screws or nails falling to the ground."
