Introduction: The Power of Fit in Performance Clothing
In the world of performance apparel, fit is everything. With Under Armour, that idea is taken to the next level. The brand has built a reputation for clothing engineered around body movement, support, and style, but shoppers often overlook one critical factor before purchasing: understanding the nuances of Under Armour clothing fit.
Before you explore our full Under Armour collection, take a moment to learn how their fit types from compression wear to relaxed cuts impact everything from comfort to performance. We’re breaking down key terms like inches vs. cm, true to size, and body shape considerations so you can shop with clarity and confidence.
Understanding Fit Types: Compression, Fitted, and Loose
Under Armour doesn’t offer a one size fits all approach. Instead, their gear is designed with three core fit types, each serving a unique performance purpose:
-
Compression Fit: Feels like a second skin. Ideal for muscle support, circulation, and performance tracking. Great for high intensity workouts.
-
Fitted Fit: Close to the body without the tightness of compression. Allows room for movement while maintaining a sleek look.
-
Loose Fit: More relaxed for comfort and layering. Best for casual wear or recovery days.
“Fit determines performance. The wrong cut can distract you; the right one enhances your game.”
Take Under Armour T-shirts as an example. A compression tee will fit tightly around the chest, waist, and torso, whereas a fitted option still follows your shape but allows breathability through stretch fabric. The loose fit variant offers maximum freedom of movement and is often chosen for its layering fit properties.
The Size Guide Demystified
When deciphering Under Armour’s size chart, it’s essential to look beyond standard labels like S, M, L. Understanding fit means understanding measurements particularly:
-
Chest (measurement) and waist (measurement) for men’s sizing
-
Bust, hip, and torso for women’s pieces
-
Inseam length for bottoms
-
Height and weight as general orientation factors
All Under Armour items are based on body measurements in inches and cm, and each product comes with a detailed size recommendation for best results.
If you're shopping Under Armour tracksuits, pay close attention to the athletic fit versus relaxed fit. Some items are designed for tailored fit aesthetics, while others lean into comfort with oversized elements. For tops, it's helpful to consider the model is wearing size X tag as a baseline.
Fit for Performance: Why Fabric Technology Matters
One of Under Armour’s defining traits is its performance fabric innovation. Fit isn't just about cut, it's also about how the material behaves. Here's a quick breakdown of tech enhanced fabrics:
-
UA HeatGear®: Lightweight and ideal for warm climates or indoor training. Often used in compression and fitted styles.
-
UA ColdGear®: Thermal insulation for colder temperatures, typically found in layered pieces or half zips.
-
UA RUSH™: Mineral infused fabric that recycles your body energy. Found in elite level apparel.
-
Moisture wicking fit and breathability are common across all gear, helping to regulate sweat and body temperature.
Looking for a base layer? Under Armour half zips are a versatile option, often made with stretch fabric and designed for easy layering without sacrificing fit personalisation.
Fit by Gender: Men’s vs. Women’s Under Armour Clothing
When it comes to Under Armour fit, one size does not fit all and that’s especially true across genders. Men’s and women’s collections are built with different body shapes in mind, and understanding these nuances is essential.
Men’s Fit Considerations
Men’s clothing is generally tailored to broader shoulders, straight torsos, and longer inseams. Key elements to pay attention to include:
-
Chest and waist measurements for accurate sizing
-
Length of sleeves and hem drop for tops
-
Rise and inseam for shorts and bottoms
For training days, our Under Armour shorts collection includes both compression and relaxed fit options. Shorts with a compression liner are perfect for HIIT sessions or running, while loose options are ideal for weight training or recovery.
Here are practical strategies to consider:
-
Try before you buy, especially with compression gear
-
If you're between sizes and prefer more freedom, size up
-
If you want a locked in feel or plan to layer, size down
-
Use fit evaluation tools when available, including photos or reviews
Every piece of Under Armour gear undergoes intense testing for fit for performance, but no two bodies are alike. That’s why it's helpful to look at options like our curated Under Armour trainers, where footwear sizing also affects how tops and bottoms complement your movement.
Fit Variations Across Product Types
Not all Under Armour products are created equal in terms of cut. Knowing how fit differs by category helps ensure you make the right selection:
-
Tops (men and women): Pay attention to shoulder width, chest measurement, and fabric flexibility
-
Bottoms: Consider inseam, waist measurement, and rise
-
Outerwear and tracksuits: These often have a looser fit to allow for layering underneath
For example, Under Armour tracksuits typically offer a relaxed fit for ease of movement, while some premium jackets incorporate tailored fit for a sleeker, streetwear-ready silhouette.
Our Under Armour sets also provide a useful way to see how different pieces layer together and behave as a unified outfit, especially when navigating mixed fit types.
Fit Considerations for Seasonal Layering
When training through changing weather conditions, layering fit becomes essential. Under Armour’s advanced fabric technologies are designed not just for climate control but for functional layering across base, mid, and outer layers.
For cooler seasons:
-
Start with UA HeatGear® as a base layer. These pieces are typically compression or fitted, designed to regulate heat without bulk.
-
Add a mid layer such as Under Armour half-zips, which offer warmth and stretch fabric flexibility.
-
Complete your outfit with UA ColdGear® outerwear for insulation without compromising movement.
Layering is where the true to size concept gets tricky. A garment that fits perfectly on its own may feel restrictive when layered. Consider sizing up outer layers or choosing loose fit options for adaptability.
Maintaining Fit Over Time
One often overlooked factor in garment sizing is how clothing behaves over time. Under Armour’s performance fabric is durable, but care practices can still impact long-term fit type and comfort.
Key tips to retain original fit:
-
Wash in cold water and avoid high heat drying to preserve fabric stretch
-
Avoid fabric softeners, which can disrupt moisture wicking fit properties
-
Follow all garment care labels, especially for compression wear and technical outerwear
Repeated wear may slightly relax the fitted or athletic fit, especially around high mobility zones like the hip and chest. If you're purchasing for intense training use, consider fit testing with smaller sizes to see how materials adapt after break in.

Frequently Asked Questions: Understanding Under Armour Clothing Fit
1. Does Under Armour clothing shrink after washing?
Under Armour garments are engineered with synthetic performance fabrics that are resistant to shrinkage. However, to maintain the original fit type, always wash in cold water and air dry when possible. High heat tumble drying may cause minor shrinkage or fabric degradation over time.
2. Are Under Armour sizes consistent across all product types?
Not always. While the size guide provides a strong baseline, sizing can vary between compression, fitted, and loose styles, as well as across different product categories like tops, bottoms, and outerwear. Always refer to product specific size info and reviews for more accuracy.
3. Is there a difference between athletic fit and fitted?
Yes. Fitted is snug but not tight, designed to contour the body comfortably. Athletic fit is more tailored, often with room in the chest and shoulders but tapered at the waist—ideal for those with a muscular build.
4. How do Under Armour youth sizes compare to adult sizing?
Youth sizing follows a different chart entirely and doesn't transition directly into adult sizes. If you're in between, refer to both body measurements and height/weight comparisons before sizing up to an adult small.
5. Can I wear Under Armour compression gear as a base layer under other clothes?
Absolutely. Compression gear is designed for layering fit and often worn under uniforms or outerwear to enhance circulation, support, and moisture wicking during performance.
6. Are Under Armour leggings see through when stretched?
Most Under Armour women’s leggings are crafted with four way stretch fabric that provides full coverage, even under tension. However, compression levels and fabric thickness vary, so lighter colourways may show more under strong light. Look for reviews or support level descriptions for transparency concerns.
7. Do Under Armour tops accommodate longer torsos?
Some styles do, particularly those marked with extended lengths or relaxed fit. Those with longer torsos may prefer sizing up or choosing from ranges like half-zips or layering gear, which are naturally cut longer for coverage during movement.
8. Is Under Armour fit better suited for slim or muscular body types?
While compression fit generally favours lean or muscular builds, loose and relaxed fits are ideal for a broader range of body types. Fitted styles strike a balance, offering flexibility for average to athletic builds. Always consult the size chart and compare to your body shape.
9. How do I know if I need high, medium, or low support in sports bras?
It depends on your activity. High impact workouts like running or HIIT require high support, medium for strength training or cycling, and low support for yoga or lounging. Each sports bra product typically includes a support level indicator to guide your choice.
10. Are there unisex styles in the Under Armour range?
Yes, some items like certain hoodies, outerwear, and accessories are designed with a unisex fit. These pieces are typically labelled accordingly and may have their own size chart, so be sure to check for guidance based on your measurements.
