You have decided to buy an Under Armour Rival Fleece Hoodie. The reviews are great. The price is right. But one question stands between you and clicking “Add to Cart”: what size should you order?

The Rival Fleece line is known for having a relaxed, comfortable fit, but getting the right size still matters. Too small, and you lose the cozy feel. Too large, and the hoodie swallows you.

Part 2: How to Measure Yourself

To use the size chart above, you need accurate body measurements. Here is how to measure each area.

2.1 Chest Measurement

Wrap a measuring tape around the fullest part of your chest, under your armpits. Keep the tape level and snug but not tight. Do not flex.

Tip: Measure with your arms relaxed at your sides. Breathe normally. Round to the nearest whole number.

2.2 Waist Measurement

Measure around your natural waistline—the narrowest part of your torso, typically just above your belly button. Keep the tape level and comfortable.

Tip: If you typically wear your hoodie lower on your hips, measure around that area instead. The standard size chart assumes waist measurement at the natural waist.

2.3 Hip Measurement

Stand with your feet together. Measure around the fullest part of your hips and seat. Keep the tape level.

2.4 Quick Reference: What Each Size Fits

Your Chest Size	Recommended Size
30″ – 32″	XS
34″ – 36″	S
38″ – 40″	M
42″ – 44″	L
46″ – 48″	XL
50″ – 52″	XXL

Part 3: Fit Notes and Considerations

3.1 The Rival Fleece Fit: Relaxed by Design

The Under Armour Rival Fleece hoodie is designed with a loose, relaxed fit. This means it will feel roomier than a standard athletic hoodie. The fuller cut is intended for complete comfort, making it ideal for lounging, layering, and everyday wear.

If you prefer a more fitted look: Some customers recommend sizing down one size. A model 186cm (6’1″) with a 97cm (38″) chest and 81cm (32″) waist wore a size Medium. This suggests that Medium fits a 38-inch chest comfortably—right at the lower end of the M range.

3.2 Model Reference: Real-World Fit

A model wearing a size Medium was 186cm (6’1″) tall with a 97cm (38″) chest and 81cm (32″) waist measurement. The fit was described as relaxed and comfortable.

3.3 Sizing Across Styles

The Rival Fleece line includes pullover hoodies, full-zip hoodies, and half-zip hoodies. The sizing is consistent across these styles. If a medium fits you in the pullover, it will fit you in the zip-up version as well.

3.4 Size Chart by Alpha Size Only

Unlike some retailers that provide garment-specific measurements, Under Armour’s official size chart for the Rival Fleece line uses standard alpha sizing (S, M, L, etc.) based on body measurements. For most customers, ordering your usual size will give you the intended relaxed fit.

Part 5: Frequently Asked Questions

Q1: Does the Under Armour Rival Fleece hoodie run true to size?

Yes. The Rival Fleece hoodie runs true to size for its intended relaxed fit. If you prefer a more fitted silhouette, some customers recommend sizing down one.

Q2: How should the Rival Fleece hoodie fit?

It is designed with a loose, relaxed fit. You should have room to move comfortably without feeling constrained. The sleeves typically reach the wrist, and the hem falls around the hip area.

Q3: What size should I order if I am 6’1″ and 180 lbs?

Based on the model reference (6’1″, 38″ chest, size Medium), a 180 lb person with a 40-42″ chest would likely be comfortable in a size Large.

Q4: Does the Rival Fleece hoodie shrink?

Under Armour garments are designed to minimize shrinkage. However, to maintain the fit, wash in cold water and tumble dry on low heat.

Q5: Is the size chart the same for pullover and zip-up styles?

Yes. The sizing is consistent across all Rival Fleece hoodie styles.

Conclusion: Size with Confidence

The Under Armour Rival Fleece hoodie is designed to fit true to size with a relaxed, comfortable silhouette. Order your usual size for the intended roomy fit, or size down once if you prefer a closer, more athletic cut.

Three things to remember:

Measure your chest – this is the most important measurement for tops
The fit is relaxed – do not expect a slim, body-hugging silhouette
When in doubt, size up – a slightly looser hoodie is always more comfortable than one that is too tight

Use the chest measurement chart above, compare it to the size guide, and order with confidence. Your perfect Rival Fleece hoodie fit is just a few clicks away.
