Best T-shirt for men to buy now.

What goes into the making of one of the best T-shirts on the market? Is it the fabric, the fit, the color or the style potential? Or a tough-to-define mixture of all of the above? In my book, it's all of the above in your search for one of the best T-shirts for men, and that's what makes the best-selling Proof 72-Hour Merino T-Shirt so downright impressive. It's sold by Huckberry, naturally, and comes from the same brand that made the Proof 72-Hour Merino Polo -- and a full lineup of the best merino gear for men. It's only a T-shirt, but it's really so much more than that as you dive into the impressive specs that separate it from the pack (and make it worth the $72 price tag). How exactly does that work out? Keep on scrolling, my friends.

The Proof 72-Hour Merino T-Shirt is a flagship product of Proof (one of the in-house brands at famed San Fran retailer Huckberry), and although it's -- again -- just a T-shirt, it's got plenty going for it in terms of utility and style. Let's start with the blend of engineered merino wool and nylon: The nylon provides durability and a touch of stretch and weather-ready performance, while merino wool naturally regulates your temperature and wicks away sweat and moisture while fighting odor. For one T-shirt to do all of that is downright impressive, yet that's exactly what you're getting with the Proof 72-Hour Merino T-Shirt.

Huckberry themselves put the Proof 72-Hour Merino T-Shirt to the test across a grueling weekend of exploration and adventure, and it came out all the better for it. The Proof 72-Hour Merino T-Shirt is machine-washable with no shrinkage, yet also designed to resist odor so you don't have to wash it quite as much. And although the Proof 72-Hour Merino T-Shirt is an investment at more than $70, it could certainly be worth picking up more than one -- all the better to give you breathable, breezy comfort throughout the entire week and perhaps an entire trip, especially if you pick one up in a versatile color. And that's another thing about the Proof 72-Hour Merino T-Shirt -- it comes in a whopping 15 colors, the kind you can mix and match with the rest of your wardrobe (including the fan-favorite Proof Rover Pants). That sure sounds like one of the best men's T-shirts to me.

The fit is designed to be snug and tailored, so consider sizing up when picking up the Proof 72-Hour Merino T-Shirt, but this is actually another positive: You can actually wear the Proof 72-Hour Merino T-Shirt as either a base layer beneath a bomber jacket or a chambray shirt, or as a darn fine T-shirt on its own for warm spring and summer days. The versatility of the Proof 72-Hour Merino T-Shirt is virtually endless: Rock one underneath a lightweight blazer alongside some of the best men's chinos at Huckberry as you head to the office, or keep the Proof 72-Hour Merino T-Shirt close at hand to wear with jeans or joggers. When you come across a stylish men's T-shirt this essential and well-made, you should do your very best to pick up as many as possible, even if they're pricier than average. Your hard-earned investment will pay off. See you out there, folks.
