Here's what I've learned dating a man with an amazing fashion sense: no matter how stylish he is on the outside, often the stuff you can't see—and yes, I mean underwear—is sadly neglected. We're talking holes, cheap material, an unflattering fit—the whole nine yards. If that sounds familiar, then this Valentine's Day, why not do your significant other (and, let's be honest, yourself) a favor? Gift him the 18-hour Jersey boxer brief from the connoisseur of stylish menswear basics, Mack Weldon. They're engineered to be ridiculously comfortable, they look as good as they feel, and because Mack Weldon is so easy to order (and re-order) from, this is a gift that guarantees to replace all the sad pairs of underwear your boyfriend's had since college for good. Besides, if he can get you sexy underwear, why shouldn't you be able to do the same for him?

Here are 4 reasons why Mack Weldon underwear is this year's perfect Valentine's Day gift.

1. 18-hour Jersey boxer briefs are insanely comfortable.

Mack Weldon takes comfort seriously. If they can't find the fabric they need, then they'll invent it—and that's exactly what they did for their 18-hour jersey boxer brief, now their most popular style. It's made from a blend of cotton, beechwood modal, and Lycra, and the fabric sits for 18 hours before it's cut so the material won't stretch out. The result? A consistent fit that's insanely durable and soft.

2. Style shouldn't end with clothing.

Just because we don't walk around in our underwear (well, all the time) doesn't mean it shouldn't look good. What sets Mack Weldon apart is their style, that perfect hard-to-achieve balance between refined and relaxed. Their secret is impeccable attention to detail a wide selection of solid and patterned designs that are more than easy on the eye.

3. It's the only "smart" underwear out there.

Mack Weldon does not mess around. Not only is the fabric innovative, but the design is too. So, what makes underwear "smart," you ask? For starters, a mesh zone to keep you fresh and cool, a signature no-roll waistband for max comfort, and a stay-put leg design that won't ride up throughout the day.

4. You're guaranteed to never have to think about buying underwear again.

With a Try-On Guarantee and free shipping with refunds, once your man knows Mack Weldon is right for him, he never has to worry about shopping for underwear again (and you won't have to bug him about it). Their fit and sizing is consistent, so simply re-order. Plus, with just one purchase you'll become a member of the loyalty program, which means awesome perks and savings on the basics men need and love.

This Valentine's Day, don't get your boyfriend another pair of cheesy heart boxers that you don't actually expect him to take seriously. With their flawless design, practical comfort, and meticulous style, Mack Weldon takes everyday basics seriously. And with over 20 colors to choose from, you're going to love how your man looks outside and in.

It seems like every polo we own is either too boxy, starts to fade after a few washes, wrinkles easily, or has a misshapen collar. The result is not being as comfortable or looking as presentable as we can for the same amount of money and effort. That's why Mack Weldon designed a polo with the perfect fit the way they do for underwear, and with Spring finally here, we wanted to try it for ourselves. Here's what we found.

1. It's ridiculously soft and breathable

Mack Weldon knows quality fabrics. They designed their micro mesh fabric by combining Pima Cotton into fine threads and finishing with a micro-mesh construction. The result is the softest and most breathable polo you will ever wear - no more stiff polos that trap all the heat. One of our editors, Bryan said "it's probably the softest shirt I've ever touched," the moment he took his out of the plastic.

2. It keeps you cool and dry.

The lightweight knit fabric using micromesh combed cotton that keeps you feeling cool all day long. You can't see it unless you hold it up to the light, but there are tons of tiny perforations for a deluxe airy feel. So when it's hot or you're playing golf, it's a lot cooler to wear, and you won't sweat as much. A GQ insider says, "It's the pro tip to looking sharp this spring without the embarrassing sweat."

3. It's stylish and crisp.

Typical polos are usually too boxy or wrinkle too easily. The Vesper polo has a perfectly tailored fit. It's a slim fit, but the fabric is forgiving, so it's never tight or uncomfortable. Turns out, it's modeled after James Bond's timeless polo that looks sophisticated while still giving you a laid. Another one of our editors jumped on the bandwagon. She shot dibs on one for her husband, so we know the girls like them too.

4. The collar won't fade and the collar won't curl.

Just like Mack Weldon aims to fix what's wrong with all men's basics, their mission extends to their polos and they promise no fade or curled collars. After several wears and washes, the navy polo is the same color as the one we never took out of the package, and the collar stayed put. We were skeptical this could be true, but their promise held up every time.

5. You can wear it anywhere.

The Vesper polo is super versatile. Paired with shorts, jeans or slacks, this polo is a no-brainer for the weekends. And tossing it on under a sport coat during the week is a comfortable and easy way to take a break from lame button-downs.
