Best Under Armour Hoodies

The best Under Armour hoodie for most people is the UA Rival Fleece Hoodie — a cotton-blend fleece in the roughly 250–290 gsm range that works for errands, casual gym sessions and layering without looking like team kit. If your priority is actual training, the UA Armour Fleece Hoodie is the stronger buy, because its brushed polyester face moves sweat, dries faster and slides under a shell with less bulk. For warm-weather workouts choose the UA Tech Terry, and for wet commutes the UA Storm Armour Fleece adds a water-repellent finish that plain fleece doesn’t have.

Quick comparison: the Under Armour hoodie lines worth knowing

Under Armour refreshes colours and small details every season, but the fabric families below have been stable for years, so they’re the right things to shop by. Weights are typical class ranges from manufacturer spec sheets rather than exact figures for a single style.

Best overall: UA Rival Fleece Hoodie

This is the one to buy if you want a single hoodie that does everything. The cotton-blend face looks like normal casual wear, the brushed back is warm enough for a 40–55°F walk, and the price sits in the $40–$60 band most people are shopping in. It suits anyone who wears a hoodie more for life than for sport.

Main trade-off: cotton absorbs sweat and holds it. If you plan to train hard in it, the fabric gets heavy and stays damp, which is exactly what the Armour Fleece and Tech Terry lines avoid. Buy the Rival Fleece for comfort, not for intervals.

Best for training: UA Armour Fleece Hoodie

Armour Fleece is Under Armour’s mid-weight polyester fleece with a smooth outer face and a brushed inner face. That combination is why it works as a midlayer: the smooth face lets a jacket slide over it instead of grabbing, and the polyester moves moisture rather than soaking it up. It suits lifters, walkers and anyone who trains outdoors in cool weather and then sits in a car.

Main trade-off: it looks more technical than a cotton hoodie, and some styles fit closer to the body. If you want a baggy, slouchy look, size up or go with the Rival Fleece.

Best lightweight layer: UA Tech Terry Hoodie

Tech Terry is a thin knit in the 180–210 gsm range — roughly a third lighter than a midweight fleece. It’s the right choice for warm-ups, indoor gyms, summer evenings and travel, where you want coverage without heat. It packs down small and layers under almost anything.

Main trade-off: warmth is limited. Below about 50°F on its own it feels thin, so treat it as a layer rather than a jacket.

Best for cold, wet weather: UA Storm Armour Fleece Hoodie

Storm styles take Armour Fleece and add a durable water-repellent (DWR) finish, so light rain beads up instead of soaking in immediately. Combined with the mid-weight fleece, that makes it the best pick for commuting, dog walks and sideline standing.

Main trade-off: DWR is a finish, not a membrane. It handles drizzle and splashes, not sustained rain, and the finish wears off over time and needs reactivating in the dryer per the manufacturer’s care instructions.

Best for deep cold: UA ColdGear hoodie styles

ColdGear fabrics are built with a brushed or grid interior that traps more air, which is what gives them a higher warmth-to-weight ratio than standard fleece. They fit closer to the body, which matters because a loose hoodie in cold wind just pumps warm air out through the hem. This is the pick for winter running, early-morning training and cold-weather layering systems.

Main trade-off: the snug fit makes it a poor casual hoodie, and it’s warmer than you want indoors. It’s also the wrong layer for mild weather — you’ll overheat and sweat it out.

Best for street wear and travel: UA Unstoppable Fleece Hoodie

The Unstoppable line sits at the top of the range with a more structured fleece, zip hand pockets, a longer body and a media sleeve. It suits people who want a hoodie that reads as outerwear, and travellers who want secure pockets and a hood that holds its shape.

Main trade-off: the highest price band here ($80–$110), and the structured fabric feels stiffer than brushed fleece until it’s broken in.

Fabric, warmth and moisture: the numbers that decide everything

Two rules follow from that table. First, weight is warmth — every 50 gsm you add is roughly a half-step in warmth, which is why a 340 gsm ColdGear piece and a 190 gsm Tech Terry hoodie are not interchangeable. Second, fibre decides comfort under effort: polyester-dominant fleece keeps moving sweat away from skin, cotton-blend fleece holds it. If you sweat heavily, the fabric matters more than the logo on the chest.

How to choose: match the hoodie to your situation

Fit and sizing notes

• Fit varies by line, not by brand. Rival Fleece is cut relaxed; ColdGear and Armour Fleece training styles are cut closer to the body. A medium in one can feel like a large in the other.
• Check body and sleeve length, not just chest. A men’s medium typically runs about 27–29 in in body length with a 34–35 in sleeve; if you’re over 6 ft or long-torsoed, look for tall sizing where the line offers it.
• Size up if layering. If the hoodie goes over a base layer plus a tee, one size up keeps the shoulders from binding. If it goes under a shell, stay true to size or the jacket will feel tight across the back.
• Hood shape matters more than you think. A three-panel hood holds its shape and doesn’t collapse into your face in wind; a simple two-panel hood is lighter and packs flatter.

Ownership realities: what wears out and how to wash it

Hoodies rarely fail in the middle. They fail at the edges, and most of that is preventable.

• First to go: cuff and hem elastic, then the drawcord and its grommets, then the DWR finish on Storm styles. Pilling shows up first under the arms and where a backpack strap rubs.
• Wash cold, inside out, zips closed. Hot water and open zippers are the two fastest ways to pill fleece and chew up prints.
• Never use fabric softener or dryer sheets. Both coat the fibres and block wicking — and on Storm styles they degrade the water-repellent finish. This is the single most common mistake.
• Dry low or hang dry. High heat shrinks cotton-blend fleece and cracks screen-printed logos. A short low-heat tumble is actually useful for reactivating DWR, per Under Armour’s care guidance, but keep it short.
• Cost per use maths: a $55 Armour Fleece hoodie worn twice a week for three years is roughly 300 wears — about $0.18 per wear. A $25 fast-fashion fleece that pills out after one season of the same use costs you several times that, which is the real argument for buying the mid-weight technical fabric even if you only ever wear it casually.

Frequently Asked Questions

Are Under Armour hoodies true to size?

Mostly, with a caveat: fit is set by the line, not the brand. Rival Fleece and Unstoppable styles run relaxed and generally match your usual size, while Armour Fleece training cuts and ColdGear pieces sit closer to the body and can feel half a size small if you’re between sizes. Check the body and sleeve length in the size chart rather than guessing from chest measurement alone.

What’s the difference between Armour Fleece and Rival Fleece?

Armour Fleece is a polyester-dominant brushed fleece designed to move moisture and layer smoothly under a jacket. Rival Fleece is a cotton-blend fleece built for comfort and everyday looks, and it absorbs sweat rather than wicking it away. Choose Armour Fleece for training and layering, Rival Fleece for casual wear.

Do Under Armour hoodies keep you warm when damp?

Polyester fleece — Armour Fleece, Tech Terry, ColdGear — keeps more of its insulating loft when damp because the fibres absorb very little water. Cotton-blend fleece does the opposite: it soaks up moisture, gets heavy and loses loft. For anything sweaty or wet, go with the polyester-dominant fabrics.

Can you put Under Armour hoodies in the dryer?

Yes, on low heat, and short cycles are better than long ones. High heat is what shrinks cotton-blend fleece and cracks printed graphics. Skip dryer sheets entirely — they leave a coating that blocks wicking and dulls water-repellent finishes. Hang drying is the safest option if you have the space.

Are Under Armour hoodies good for the gym?

Yes, if you pick the right fabric. A mid-weight Armour Fleece or lightweight Tech Terry hoodie handles warm-ups, cool gyms and outdoor sessions well because both wick and dry quickly. A heavy cotton-blend hoodie is a poor training choice — it holds sweat and stays damp through a session.

How do I keep the water-repellent finish on a Storm hoodie working?

Wash it in cold water with a mild detergent and no softener, then tumble it on low heat for a short cycle — the heat helps reactivate the DWR finish, per the manufacturer’s care instructions. If water stops beading after repeated washes, a wash-in water-repellent treatment can restore it. Remember the finish sheds light rain only; it isn’t a rain shell.
