The more you learn about improving your style — heck, improving your lifestyle in general — the more important it is to realize the little details make a big difference. That’s what we talk about all the time at The Style Guide, and it’s always nice to get a reminder. That goes right down to what you’re wearing beneath your jeans or chinos — your underwear. Yes, that’s right. A great pair of underwear fits, feels and performs better — that’s what Mack Weldon has set out to perfect. It’s also why you should set out to upgrade your top drawer as soon as you can, as I’ve learned in testing out the brand over the past several months.

The E-commerce basics brand, a previous participant in this site’s Style Pick of the Week series, mixes the approach of a nimble start-up with the quality and attention to detail of a much larger brand — and the results show. Seriously, Mack Weldon underwear is what your top drawer needs, as soon as possible. The brand was founded on the process of simplifying basics shopping, and one look at the site makes it easy — pick your color, pick your size, a  few clicks and boom… new underwear. Much easier than the department store experience rifling through bin after bin.

And if retooling your underwear drawer feels daunting, fear not — the brand’s Try-on Guarantee implores you to just test it out. If the fit, fabric or feel isn’t right, the brand will issue you a refund or send you a different size, color or style — it’s that easy. You can even keep the pair you tried on. That’s how confident they are that you’ll love it. Not a bad deal, ehh?

Not that you can necessarily go wrong with something like the reliably made, comfortable 18-Hour Jersey Boxer Briefs. If you’re going to start with one purchase, make it these. Having tested them out myself through spring, summer, fall and winter in New York City, the fabric is durable yet extremely comfortable, the fit is great (particularly the Stay-Put Legs to prevent ‘em riding up) and touches like mesh cool zones help out immensely. I’ve worn Mack Weldon in the heat at Panorama NYC, I’ve worn ‘em tromping through the snow with a naval-inspired jacket, and the brand doesn’t let me down — that goes for pieces like its Merino Long-Sleeve Tee, too.

Unlike other underwear, the waistband is sturdy and doesn’t curl over — again, it’s the little details that make a difference. And it should come as no surprise  that the brand engineers its own fabrics — and generates great customer feedback along the way. It’s almost too easy to list out the things they do so well — quality, great comfort, top-notch fabric, excellent fit, an array of styles for every taste … that’s a win all around for stylish guys, and I’d bet you’ll be among those happy customers soon enough.

They’ve taken the same nuanced technical and quality-oriented approach and put it to practice throughout the whole line. The brand’s Silver line of boxer briefs in particular makes use of another crucial and oft-overlooked design factor —  handy antimicrobial and anti-odor performance fabric in the way of Silver XT2. Yes, it’s made with a bit of actual pure silver woven into the fabric. Sound fancy? In short, you still get the same great fit and the ability to stay cool in the heat — or comfortable in the winter.

So from A to Z, Mack Weldon underwear gets it right — fit, reliability, comfort, performance and the brand’s word that you’ll love what you buy. Take my word for it and get shopping — will ya?
