Golf is full of passing trends — sliding weights, white belts, flat brims, etc. What is here today is often long gone tomorrow. More specifically, what is in your bag in May often doesn’t make it to Thanksgiving before being doomed to back-of-the-closet golf purgatory.

It’s only natural: that sick new driver comes out and you’ve gotta have it. You thought you could pull off red pants and you clearly cannot. This putter won’t putt anymore. Replace, replace, replace.

This is the revolving door of golf gear in your life, which is all well and good — new gear feeds the soul. But how about something with a little staying power? You need a few timeless, rugged and unique golf goods that will be with you for the long haul. And for less than $100, you may have them.

Whether it’s the permanent cool of a classic shirt, or the leather good that takes on more life with every round and season, this budget-friendly gear will stick around through the fads and trends. Unlike your long game, it will stand the test of time.

1. Dagwood Golf “Wilson” leather scorecard wallet €69.00 (www.dagwoodgolf.com)

The Wilson scorecard wallet from bespoke house Dagwood Golf is that rarest type of golf accessory: one you might someday hand down instead of throw out. Let’s face it — most golf gear doesn’t fall into the heirloom category. “Son, I’d like you to have my 1991 Footjoys,” is not happening (even though that was probably a pretty good shoe). The simple fact is that the shine starts to come off most new gear pretty quickly, as obsolescence looms and newer stuff lurks.

Compare that with the timelessness of the Wilson scorecard wallet. The first thing to do when taking possession of said item is to hold it to your nose and inhale the incredible life-giving scent of vegetable-tanned Italian leather. You’re welcome. Now turn the wallet over in your hands a few times, undo the clasp and open it. That simple act will never get old, even if you’re opening it to mark down a snowman.

Inside is a notebook (the stat-tracking system of 100 years ago), an elastic band and four flaps to hold a scorecard in place. Measuring 15×11 centimeters, with a pencil holder underneath the clasp, the Wilson is perfect back-pocket size. The design typifies Dagwood’s aesthetic. Based in Berlin, this boutique company produces gear that is at once traditional and modern, and with a heavy dose of history. Call it progressive nostalgia. In a golf world that is increasingly digital, Dagwood is defiantly — and brilliantly — analog. And like anything anachronistic and beautiful, the Wilson scorecard wallet is one of those things you can’t stop touching. This old friend is going to be with you for a long, long time.

2. Seamus Golf Wool Headcover $75 (www.seamusgolf.com)

As makers of hand-crafted, custom woolen headcovers, Seamus Golf was founded on a simple idea: different is better. Golf is an individual sport, after all. It is also a lifestyle. So why should everyone’s gear look the same — a homogeneous sea of big company names and logos? Lame.

Your bag should be your own, and your headcovers should reflect your personal style and taste. This is the gospel according to Seamus. Now, if your personal style is expressed by having a stuffed donkey for a headcover (which is cool), Seamus is not the place for you. If, however, you’re into classic Scottish and European tartans and tweeds, then Seamus is the promised land.

Using highly durable wool sourced from mills in the Pacific Northwest and the UK, Seamus designs, hand cuts and sews everything in its Oregon shop. These are headcovers that would be at home in the hallowed clubs of the British Isles, where, as we all know, they keep it real.

Take the Stewart Blue Dress headcover, named after a family descended from the 4th High Steward of Scotland. Featuring white, blue, brown and green, this tasteful tartan will set your bag apart from the crowd and be a sharp looking part of your gear for years. As drivers come and go, this will stay.

Not a fan of the 4th High Steward of Scotland? No problem! Seamus’ selection is huge, and even includes a “Mahalo” line of Hawaiian patterns, if that’s your thing. And if you can’t find something you like in their vast inventory of designs, they’ll sew you up a custom job. That vinyl atrocity of a headcover that came with your driver doesn’t stand a chance.

3. Linksoul End-On-End Striped Knit Shirt $72 (www.linksoul.com)

Admit it: that Rory McIllroy neon yellow-and-black shirt you bought last year is already starting to look like a bad idea. (Here’s to hoping you didn’t go all-in on the yellow belt too.) A golf shirt should stand the test of time — both fashion time and actual time — and too often the shirt that shines twice as bright, you wear only half as long. You need a classic.

Linksoul, an Oceanside, Calif., golf lifestyle brand, blends an easy SoCal surfer vibe with heritage links style and feel — classic looks with a modern twist. There are no garish colors or patterns here that you’ll eventually regret or outgrow, just a less-is-more aesthetic that will last.

The End-on-End Stripe Knit Shirt is a great example. Made with alternating light and dark threads and exposed stitching, this all-cotton shirt has a subtle texture and casual feel that says “I don’t care if I sink this birdie putt or not.” It also says, “I may or may not surf,” and “I may or may not drive a killer old-school Land Rover.” These are all very positive things. Available in 10 solid color options, you can wear this shirt with anything, anywhere. Better, you can wear it whether you’re 20 years old or 70. There’s no guaranteeing it will last 50 years, but hey, you never know. Either way, your style game just got permanently upped.

4. Jones Classic Shoe Bag $44.95 (www.jonesgolfbags.com)

Everything old is new again. Before the golf manufacturing world came to be dominated by the modern-day behemoths we all know, there was the Jones Sports Co., makers of the golf bag your dad had in the 70s. You know the one — skinny, single strap, looked like something Danny Noonan would carry on caddy day at Bushwood. Then the 70s ended, and the Jones name push-faded into obscurity. Now it’s back, and here to stay.

Relaunched in recent years, Jones stands as a retro-minimalist answer to the modern equipment landscape, and now offers an expanded line of gear. Ergo, the Jones Classic Shoe Bag, an ode to simplicity and effortless cool.

First off, you need a shoe bag. Whether you’re wearing Nebulonis or Nikes, you shouldn’t be tossing your golf shoes into the trunk with the jumper cables, or manhandling them into the rain gear pocket of your bag. A shoe bag is essential! The Jones Classic is big enough for your size 13s, and features the Jones signature twist handle, a zippered storage pocket, velour lining and dual vents. It also comes with a monogram option in five different fonts (suggestion: “Noonan” in Brush Script). Above all, this utilitarian 70s masterpiece comes with a lifetime supply of throwback hipness. Dig it.

5. Kentwool Tour Profile Socks $19.95 (www.kentwool.com)

If you’re going to call your sock “The World’s Best Golf Sock,” you’d better have something to back it up. Luckily, Kentwool does. The family-owned South Carolina company has been in the textile business for more than 170 years, but only began making golf socks in 2008. They may have found their true calling.

Using a proprietary blend of hypoallergenic fine Merino wool and other fibers, the company employs what it calls WINDspun technology to construct a sock that all but does away with abrasion and significantly reduces foot fatigue. And while most golf socks offer less support than Phil Mickelson after a Ryder Cup loss, Kentwools create a surprisingly stable feel around your foot, all while serving up extra helpings of cushiony wonderfulness, moisture wicking, and odor control. Compared to those thin cotton numbers you’ve been disrespecting your feet with for years, the Kentwool Tour Profile will be a revelation. A number of Tour pros have seen the light, including Bubba Watson (and if a sock can get on that guy’s good side, it must be doing something right).

Above all, Kentwools are made to last, and come with a Lifetime Blister-Free Guarantee. Even better, they come in an array of awesome color choices, including a new “Game Day” collection and a “Bubba Green,” named after the man himself. Whoever said socks can’t be cool never put on a pair of Kentwools.

6. Sundog “Default” sunglasses with True Blue lens $69.99 (www.sundogeyewear.com)

The definitive guide for purchasing sunglasses is rightly credited to Texas blues-rock titans ZZ Top, who in its 1980 hit “Cheap Sunglasses” advised those in the market for tinted eyewear to “go out and get yourself some thick black frames, with the glass so dark they won’t even know your name.” The band also clearly emphasized that such glasses should be affordable. This remains solid advice, and Sundog Eyewear is here to help you take it.

As makers of affordable sports sunglasses, the company’s golf line checks all the boxes for players who want durable, quality glasses, but don’t want to blow half a year’s golf gear budget on them. Sundog also offers more than just the “I’m cycling in the Tour de France” sport look. The “Default” model, for one, is a refreshing throwback style fit for golfers interested in a more casual lifestyle vibe. But make no mistake — the Defaults are made for play. They stay snuggly and comfortably in place.

But the secret weapon of these shades are their True Blue lens — a techy new lens specifically designed to filter blue light, something most lens don’t do. Traditionally, ultraviolet (UV) light has gotten a bad rap when it comes to damaging your eyes, hence polarized sunglasses. In recent years, however, studies have shown that blue light — which is visible light that appears blue — is just as damaging to your eyes over time.

True Blue lenses use a combination of melanin and something called Ocular Lens Pigment to mimic and enhance the body’s own defense mechanisms against blue light damage. On the course, this translates into reduced glare, enhanced definition and lessened visual strain. It’s a cool view. On the downside, these sunglasses will take away the “too much blue light” excuse when you three putt. Small price to pay.
