Here are some key features of ColdGear:

  • Dual-layer fabric – Inner layer manages moisture while exterior retains warmth
  • Smooth inner lining – Slicks away sweat from skin for quicker evaporation
  • Brushed outer layer – Insulates body heat and dries fast
  • Athletic fit – Snug shape mirrors natural contours to trap warmth
  • Moisture Transport System – Wicks perspiration away from skin
  • Anti-odor technology – Prevents growth of odor-causing microbes
  • 4-way stretch – Allows full mobility and stretch in every direction
  • UPF 30+ sun protection – Guards against harmful UV rays
  • Variety of tops & bottoms – Base layers, mock necks, leggings and more

ColdGear is engineered to maintain warmth, keep you dry, and protect against the elements – perfect for training and playing sports outdoors in cold weather.

Overview of Under Armour HeatGear

In contrast to ColdGear, HeatGear features a smooth, single-layer construction designed to enhance breathability and moisture management. The looser fit and lightweight material help release excess body heat.

Here are some notable features of HeatGear:

  • Lightweight smooth fabric – Promotes maximum airflow and ventilation
  • Loose compression fit – Reduces overheating and allows air circulation
  • Moisture Transport System – Wicks sweat away from skin quickly
  • Anti-odor technology – Prevents growth of odor-causing microbes
  • 4-way stretch – Unrestricted mobility in every direction
  • UPF 30+ sun protection – Guards against harmful UV rays
  • Mesh panels – Strategically placed for extra ventilation
  • Variety of tops & bottoms – Base layers, tees, tanks, leggings and more

The ultra-breathable construction of HeatGear allows it to keep you cool, dry, and comfortable even during intense training in hot weather conditions.

Key Differences Between ColdGear and HeatGear

While both product lines share Under Armour technologies like moisture management and stretch fabric, they differ significantly when it comes to temperature regulation:

1. Fit

ColdGear and HeatGear are designed with different fits to suit varying weather conditions. ColdGear features an athletic compression fit, snug against the body to retain warmth, ideal for chilly conditions.

This close fit acts like a second skin, keeping the body’s natural heat in, and the cold out. HeatGear, on the other hand, has a looser fit to encourage air circulation. This is important in warmer climates where cooling down is essential to remain comfortable.

2. Fabric

Fabric technology is integral to the function of both gear types. ColdGear employs a dual-layer brushed fabric.

This means that it has two layers, with the inner layer designed to retain body heat and the outer layer working to protect against the cold.

The brushed texture adds an extra layer of insulation. In contrast, HeatGear uses a smooth, single-layer fabric that enhances breathability, keeping users cool by allowing heat to escape and fresh air to circulate.

3. Ventilation

Ventilation is crucial for temperature regulation. ColdGear, with its tight construction, restricts airflow to maintain warmth. It’s like bundling up in a cozy blanket on a cold day.

HeatGear uses mesh panels to increase airflow, a feature much needed in warm weather. These panels act like little windows, letting the breeze in and keeping the body cool.

4. Weather

ColdGear and HeatGear are optimized for opposite weather conditions. ColdGear is your go-to for colder, dry climates. Think of it as your winter coat, keeping you warm when the temperature drops.

HeatGear is the choice for warmer, humid conditions, acting like a light T-shirt on a hot summer day, helping your body stay cool and refreshed.

5. Layering

Layering is an effective method to manage body temperature. ColdGear is versatile as it can be used as a base or mid-layer, depending on the intensity of the cold. It’s like adding layers of clothing on a particularly cold day.

HeatGear is ideal as a lightweight base layer, ensuring you don’t feel weighed down in the heat. It’s akin to wearing a light tank top beneath your outfit on a sunny day.

6. Warmth

Warmth management is at the core of these gear lines. ColdGear acts like a thermal flask, keeping your body heat close and ensuring you stay warm in cold conditions.

HeatGear, alternatively, releases excess warmth, much like opening a window in a stuffy room to let out the heat and let in the cool breeze.

7. Breathability

Breathability is about balancing warmth and ventilation. While HeatGear prioritizes ventilation, ensuring you’re not overwhelmed by the heat, ColdGear leans more towards insulation. Imagine ColdGear as a warm, insulating wall, and HeatGear as a ventilated, airy space.

8. Activities

Different activities require different gear. ColdGear is designed for winter sports, like skiing or snowboarding, where staying warm is crucial. HeatGear is for summer sports, like running or basketball, where staying cool can enhance performance.

9. Wind Resistance

Wind resistance is an added benefit for outdoor activities. ColdGear offers higher wind resistance, acting like a shield against chilly winds. HeatGear, being more breathable and lightweight, doesn’t offer as much protection against the wind, focusing more on keeping you cool.

ColdGear traps heat while HeatGear releases it, making the products suited for opposite ends of the weather spectrum.
