Choosing an Under Armour men’s fleece sweatshirt: a practical guide to warmth and comfort

An Under Armour men’s fleece sweatshirt might seem like a straightforward purchase at first. But small differences in fabric, fit and finish can determine whether you mainly wear it at home, use it for training or pair it with jeans and joggers every day.

Many shoppers come up against the same pitfalls:

  • “Fleece” is mistaken for 100% polyester. Many Under Armour sweatshirts are actually cotton-polyester blends. They can feel comfortable, but have different properties from technical sports fleece.
  • A relaxed fit isn’t always clearly stated. Some Rival Fleece styles are described as having a loose fit. If you’re between sizes, you could end up ordering a sweatshirt that’s too roomy.
  • A warm lining doesn’t tell you everything about how to use it. A brushed inner face can feel extra soft and warm, but weight, freedom of movement and care are just as important for intense training.
  • Colour and size are only checked after opening the product page. Availability can vary by style. Always check the current size options before you pay.

Which specifications should you check?

1. Fabric: cotton blend or technical material?

A men’s cotton sweatshirt usually feels soft and familiar. The Under Armour styles in this selection are mainly made from cotton-polyester blends:

  • Rival Fleece crew and hoodie: 78% cotton and 22% polyester or, for certain hoodie styles, 80% cotton and 20% polyester.
  • Icon Fleece crew: 80% cotton and 20% polyester.

Cotton is comfortable for everyday wear, while polyester can help the garment keep its shape and reduce drying time. This doesn’t automatically mean a style is suitable for every type of sport. A cotton blend is often practical for walking, warming up, travelling and relaxing. For very intense training, you’ll also want to consider ventilation and freedom of movement.

For the Icon Fleece style, the product information mentions odour-control technology. According to Under Armour’s product information, it’s designed to reduce odour. Treat this as a brand claim, and check the product details if it’s an important factor for you.

2. Inner face and warmth

A warm men’s fleece sweatshirt often has a brushed inner face. This is part of the product description for the Rival Fleece and Icon Fleece styles mentioned here. The finish can feel soft and provide extra warmth when layering.

Pay attention to the cuffs, collar and hem too. Ribbed edges help keep the sweatshirt in place and limit draughts around your wrists and waist. For outdoor wear, hoodies also have handy features such as an adjustable drawcord and a kangaroo pocket.

3. Fit and chest measurement

Sizing can vary between collections. Rival Fleece styles are described as regular fit, but the product information also notes that they can come up roomy. The stated chest measurements are:

  • S: 86–94 cm
  • M: 94–104 cm
  • L: 104–112 cm
  • XL: 112–122 cm

The size chart for the Icon Fleece crew runs from S to XXL. It’s described as a classic regular fit, with chest measurements including 86–94 cm for S, 94–104 cm for M and 104–112 cm for L.

Measure your chest while standing comfortably and compare it with the chart on the product page. If you want room for a T-shirt and a thin base layer, don’t rely on your usual clothing size alone. For a roomier-fitting Rival style, sizing down may work; check the size recommendation for each style.

Care and durability

Always follow the care label on the specific garment. The Under Armour styles mentioned here include instructions to:

  • wash on a cold cycle with similar colours;
  • do not use bleach;
  • tumble dry on a low setting;
  • do not use fabric softener;
  • do not dry clean;
  • do not iron.

The exact instructions on the label take priority. Washing the sweatshirt inside out and avoiding unnecessarily high drying temperatures can help keep its colour, shape and print looking good for longer. After buying it, check the seams, trims and fit before removing the tags.

Frequently asked questions about Under Armour men’s fleece sweatshirts

Is a fleece sweatshirt suitable for everyday wear?

Yes, a cotton blend with a brushed inner face is practical for wearing at home, on the go, for walking and as a layer. For intense sport, it’s also worth considering ventilation, fit and freedom of movement.

Which size Under Armour Rival Fleece should I choose?

Compare your chest measurement with the size chart on the product page. Rival Fleece is described as regular fit, but can come up roomy. If you’re between sizes, bear the suggestion to “consider sizing down” in mind when choosing.

What’s the difference between a crew-neck and a hoodie?

A men’s crew-neck sweatshirt has a round neck and is usually easier to wear under a jacket. A hoodie has a hood and often a kangaroo pocket. Choose a crew-neck for versatile casual outfits, or a hoodie if you’d like extra coverage around your head and neck.
