You’ve probably seen that glint of the silver logo in every weight room from Brooklyn to Berlin. It’s basically a uniform at this point. When people talk about under armour hoodies men usually fall into two camps: the guys who swear by the original "ColdGear" tech and the ones who just want a sweatshirt that doesn't lose its shape after three washes. Honestly, the market is flooded with fleece right now. You’ve got high-end "athleisure" brands charging $150 for a cotton blend, and then you have the bargain bin stuff that feels like sandpaper after a trip through the dryer. Under Armour sits in this weird, effective middle ground where they actually obsess over the science of sweat.
It started in a basement. Kevin Plank, the founder, was tired of changing his soaked cotton T-shirt multiple times during football practice at the University of Maryland. He wanted something that didn't hold water like a sponge. That obsession with moisture-wicking eventually bled into their outerwear. It’s not just about being warm; it’s about not feeling like a wet towel once you start moving.
The Tech Inside Under Armour Hoodies Men Actually Use
Most people just grab a hoodie because it looks cool, but there is actual engineering happening in the fabric. Take the Armour Fleece. It’s their original performance replacement for old-school fleece. It’s light. It’s breathable. It stretches for superior mobility. If you’ve ever tried to do an overhead press in a stiff, heavy cotton hoodie, you know the struggle of the hem riding up to your chin. This stuff moves with you.
Then there’s the Rival Fleece. This is the one you see everywhere. It’s a bit heavier, more of a "lifestyle" piece, but it still has that soft, brushed interior that traps heat. If you're walking the dog in October, this is the one. But if you’re actually training outside in sub-zero temperatures, you’re looking for ColdGear Infrared. They use a soft, thermo-conductive inner coating to absorb and retain your own body heat. It sounds like sci-fi, but it’s really just clever material science. They basically printed a ceramic pattern on the inside of the fabric that holds onto the infrared energy your body naturally kicks off.
Is Storm Technology Really Waterproof?
Let’s be real for a second. There is a lot of marketing fluff in the fitness world. Under Armour has this thing called UA Storm. They claim it "repels water without sacrificing breathability." Is it a raincoat? No. Don't go standing in a monsoon and expect to stay bone-dry. However, if it’s drizzling or snowing, the water literally beads up and rolls off the surface.

It uses a DWR (Durable Water Repellent) finish. The cool part is that it doesn't feel like a plastic bag. Most waterproof gear is crunchy and loud. Storm tech feels like a normal sweatshirt. It’s perfect for those damp, gray mornings when you’re questioning your life choices on the way to a 6 AM workout. Just don't expect it to replace a Gore-Tex shell in a downpour.
Why the Fit Varies So Much
One of the biggest complaints you’ll hear is about the sizing. It’s confusing. UA uses three main fits: Loose, Fitted, and Compression. Most under armour hoodies men buy are the "Loose" fit. This is designed to be oversized and comfortable. If you’re a medium in most brands, a "Loose" Medium from UA might feel like a tent.
- Loose: Full cut for total comfort. This is your couch-surfing or post-gym pump cover.
- Fitted: Sits close to the skin but isn't tight. This is the sweet spot for most athletic guys.
- Compression: This is rarely used for hoodies, but some base-layer "hoodies" exist in this category. It feels like a second skin.
If you have a broader chest or shoulders, the Rival Fleece series is usually a safer bet. It has a more traditional "American" cut. On the flip side, the Project Rock collection—the stuff endorsed by Dwayne Johnson—often runs a bit more tailored in the arms. It’s meant to show off the work you’ve put in at the gym.
The Project Rock Factor
Speaking of "The Rock," his line is a massive part of why the brand stayed relevant when competitors like Lululemon started eating their lunch in the lifestyle space. The Project Rock hoodies aren't just a name-drop. They usually feature "Charged Cotton." This is a blend that feels like natural cotton but dries much faster. It’s heavier than the pure polyester stuff. It feels "tougher." When you’re tossing around iron, you want something that feels substantial. These hoodies usually have reinforced seams and heavier ribbed cuffs. They are built to be beaten up.

Common Misconceptions About Synthetic Fabrics
People often think polyester is "cheap." Well, in some cases, it is. But high-grade performance polyester is actually quite expensive to manufacture correctly. The problem with cheap hoodies is "pilling"—those annoying little balls of fuzz that show up under the arms. Under Armour’s higher-end hoodies use long-staple fibers and specific knit patterns to prevent this.
Another myth? That you can’t wash them with fabric softener. Actually, that one is true. Stop using fabric softener on your performance gear. The softener leaves a waxy coating on the fibers. This clogs the "pores" of the fabric, which completely kills the moisture-wicking properties. Your $70 hoodie will start to smell like a locker room because the sweat gets trapped in that waxy layer. Wash them in cold water, skip the dryer sheet, and let them air dry if you can. They’ll last five years instead of five months.
Sustainability and the Future
Under Armour has been under some pressure lately to catch up on the eco-friendly front. Brands like Patagonia have set a high bar. In response, UA has started moving toward more recycled polyester. They’ve also been looking at "dope dyeing," a process that colors the fibers before they’re even spun into yarn. This saves a massive amount of water and energy compared to traditional vat dyeing.
They also launched the UA Forest initiative, focusing on creating more circular products. While they aren't quite at the "100% organic" stage for everything, the shift is noticeable in their newer seasonal drops. You'll see more "made with recycled content" tags on the inner seams of the newer hoodies hitting shelves this year.

How to Spot a Fake
Because under armour hoodies men are so popular, the counterfeit market is everywhere. You’ll see them on sketchy websites for $15. Don't do it.
- Check the tags: Real UA gear has high-quality, heat-sealed neck labels or very crisp, printed tags.
- Feel the weight: Cheap fakes use thin, "shiny" polyester that feels like a Halloween costume.
- Look at the logo: The UA logo should be perfectly symmetrical. If the "U" and the "A" look slightly off-center or the stitching is messy, it's a dud.
- The Zipper: They almost exclusively use YKK zippers. If the zipper feels flimsy or gets stuck easily, it’s probably not genuine.
Practical Advice for Choosing Your Next Hoodie
If you’re still undecided, here is the breakdown of what to actually buy based on what you’re doing.
- For pure comfort and lounging: Go with the Rival Fleece. It’s the softest. It feels like a hug. It’s got that classic kangaroo pocket and a drawcord hood.
- For outdoor running in the cold: Look for ColdGear Infrared. It’s thinner than a standard hoodie but keeps you twice as warm. You won't feel like the Stay Puft Marshmallow Man while you’re trying to hit your splits.
- For the hardcore lifter: The Project Rock line is the gold standard. It’s durable and handles chalk and barbell knurling better than the lighter fabrics.
- For rain and unpredictable weather: Anything with the UA Storm logo. It’s the difference between being slightly damp and being soaked to the bone.
Ultimately, the reason these hoodies stick around isn't just the marketing. It's the fact that they don't fall apart. You can throw a Rival Fleece in the wash fifty times, and the cuffs will still be tight. The hood won't lose its shape. In a world of "fast fashion" that ends up in a landfill after three months, there’s something to be said for gear that actually survives a workout.
Next Steps for Your Gear
Before you click "buy" on the first thing you see, take a look at your current rotation. If you find yourself constantly overheating, move away from the heavy cotton blends and look for the Armour Fleece or Iso-Chill variants. Check the size guide specifically for the "Loose" versus "Fitted" designations to avoid the hassle of a return. Finally, remember to flip your hoodies inside out before washing to protect the outer finish and the logo from the agitator in your washing machine. Keeping the fabric clear of softeners will ensure that the moisture-wicking tech actually does what you paid for it to do.
