Amping up your rotation of summer style essentials hits a new level when you decide to invest even in the best everyday menswear — picks that you can wear frequently, without worrying that they’re versatile enough or well-made to stand up to repeat wear.

In my experience, Billy Reid menswear hits all the right notes if you want luxe-yet-accessible men’s style essentials, ones with a bit of flair and yet plenty of easy-to-wear potential.

What exactly do I mean by that? Well, picture your favorite pair of chinos. Now, merge them with some of the best jeans for men. What do you get? A pair of pants I personally love, the Billy Reid Cotton-Linen 5-Pocket Pants. From sunrise to sunset (and beyond), these premium men’s pants are a major hit in my book, with durability and versatility in spades.

Billy Reid already makes plenty of summer menswear must-haves, particularly one of the best linen shirts, and these five-pocket pants are a nice complement to the award-winning designer’s slightly more casual staple picks.

The Billy Reid Cotton-Linen 5-Pocket Pants (with a blend of 78 percent cotton for structure and 22 percent linen for breathability) boast a stylish slim fit, but in my experience, Billy Reid slim-fit pants aren’t overly slim — they’re very nearly just right.

The Billy Reid Cotton-Linen 5-Pocket Pants feature durable antique brass hardware, right down to the brass tack button that gets an embossed Billy Reid stripe treatment. It’s the sort of small detail that makes these pants worth the higher price tag than your typical pair of jeans, chinos or even linen pants (the Billy Reid Cotton-Linen 5-Pocket Pants clock in at $198).

The garment-wash process gives them a soft handfeel right out of the box, which is ideal — from Oxford shirts to one of the best pocket T-shirts, you’ll want to work these pants into your warm-weather menswear rotation ASAP. That’s the sort of style upgrade you really can’t beat, and that’s why I trust Billy Reid with my summer style must-haves.

There are tried-and-true staples in every guy’s rotation of the best menswear, be it a trusty T-shirt, a stylish polo or even a laidback, rugged henley. But it’s nice to take a slight style swerve off the beaten pat every once in a while by embracing a style that’s retro yet modern, fresh and ever so slightly on trend without overdoing it.

In my experience, at least in the summer heat of Brooklyn, you can check off all those boxes perfectly with one of the best camp collar shirts for men. And this season, I’ve found that the best camp collar (or Cuba collar) shirts for guys come from one of my favorite retailers: The great folks at Buck Mason, a West Coast brand with a flair for modern takes on iconic styles (like the shirt in question today).

The camp collar shirt dates back well before modern fashion runways, as the style was worn by field workers in the heat of Cuba and included additional details like front hip pockets. The fabric and fit was breezy and cooling, the lay-flat collar also helped with breathability and the overall impact was easygoing yet useful.

Today, the best camp collar shirts check off many of those same boxes, and for my money’s worth, the Buck Mason Draped Linen Camp Collar Shirt is among the best of the bunch.

It’s somewhere between a polo and a T-shirt — perhaps dressier than both items, but as comfortable and easy to wear as your favorite Buck Mason tee. It works wonders with chino shorts and canvas sneakers, yet the best camp collar men’s shirts are also wearable with linen trousers and leather loafers. It can be dressed up or dressed down simply on its own (no blazer needed), which is more than I’ve found with even the best T-shirts, for instance.

In short, any #OOTD that might call for a classic polo can reasonably work with a style move like the Buck Mason Draped Linen Camp Collar Shirt. And lest you think this camp collar is too “off the wall,” consider the fact that it comes in a crisp, timeless color like Dark Navy.

While the lay-flat collar is a change of pace — and it’s a detail that took me some getting used to — this stylish men’s short-sleeve shirt works just about as well as anything in your off-duty wardrobe, from BBQs to beach days and beyond.

Rest easy knowing the linen-blend fabric is ultra-soft and comfortable in the heat, the fit is relaxed without being overly baggy — an XL works on my 6’2″ frame — and the style points are tough to top with one of the best camp collar shirts for men this season. Try it on for size and unlock a new level of summer style points.

If you’ve been reading my Brooklyn style blog, you know I’m all about the idea of finding a one-stop shop for the best men’s style essentials, and then keeping a frequent eye on that same retailer. In this instance, the retailer happens to be Bespoke Post.

In addition to its own line of menswear essentials, the NYC-based upstart stocks and sells some of the coolest menswear and gear around, including a few stellar picks from a familiar Austin company, Howler Brothers, which happens to be the subject of several Howler Brothers reviews here on the site. That’s where today’s post dives into a must-have summer shirt, one that happens to be 25 percent off right now.

When it comes to the Howler Brothers Gaucho Western Snapshirt, you’re getting what the brand calls a shirt with a “modern touch to vintage Western wear,” and they’re absolutely correct. In my experience, the Howler Brothers Gaucho Western Snapshirt lives up to that billing and then some.

It starts with a durable cotton-polyester-spandex build that’s more performance-minded than other Western shirts (even if your main focus on performance happens to be manning the grill or fetching another cold beer).

The real kicker with the Howler Brothers Gaucho Western Snapshirt, though, is the use of inventive and distinctive chest embroidery, which gives it that sense of vintage style.

Snap chest pockets and front snap hardware nail down the Western shirt vibe, and again, in my opinion, it doesn’t hurt that the versatile Howler Brothers Gaucho Western Snapshirt is 25 percent off via my pals in the Bespoke Post sale section.
