Nike Warm Weather Gear

Every year, you see the same thing — warm weather training gear and cold weather training gear. Tights for 75-degree weather and tights for 0-degree weather. But what makes them different? When two pairs of tights looks the same, how can one keep you cool and one keep you warm? Technology, that’s how. It’s December, so let’s look at the cold side first.

Cold Weather Gear

Nike and Under Armour have made tremendous strides with cold weather training gear. Gone are the days of jogging in light grey sweat suits. Seriously, if you still wear that, you NEED to read this. Enter the days of lightweight performance and fitted style. It’s all about wearing one heat-locking base layer, so you only have to throw on shorts and a training hoodie before you head outside for a workout.

The key is to effectively trap body heat, so you’re essentially keeping yourself warm. Under Armour ColdGear does this incredibly well with its two apparel options: Infrared and Armour. Both keep you warm, but in different ways. Infrared apparel uses thermo-conductive technology that actually absorbs your body heat and retains it, keeping you warmer, longer. It’s all very scientific, but you can learn more about it in our latest Behind The Tech post.

The Armour apparel, on the other hand, has a premium brushed interior, so it’s as comfortable as it is warm — you’ll never want to take it off. It acts as a second skin that blocks cold air and moisture to keep you warm without weighing you down.

Like Under Armour, Nike has different levels of cold weather gear: Pro Warm (For 45°-60°F), Pro Hyperwarm (For 32°-45°F), and Pro Hyperwarm Max (For 32° and below). The special part about Nike’s gear is that it doesn’t just trap the heat you produce while you work out — it actually regulates your temperature so you don’t overheat. All three levels feature breathable panels in high-heat zones, so while your body temp continues to rise, heat can escape to keep you at a comfortable temp. Cold weather never stood a chance.

While cold weather gear retains all your heat, the warm weather gear releases it. Sure, it’s a simple idea, but the technology behind it is pretty complex. There’s much more to it than some mesh panels. Check it out.

UA’s HeatGear is loaded with amazing tech. Two of its most innovative additions are Charged Cotton and coldblack technology. UA didn’t just start using a new fabric. It changed cotton! The experts at Under Armour took the most recognized fabric on the planet and drastically improved it. Regular cotton holds sweat and weighs you down. Charged cotton is incredibly soft, it wicks sweat, and it dries faster. And coldblack technology is even cooler. Built into the dye, it reflects heat and sun rays so dark colors don’t get as hot. Essentially, it feels like you’re working out in the shade. That’s true innovation.

The Swoosh is all about staying light and breathable. Nike’s Pro Cool and Pro Hypercool are the lightest layers Nike has to offer, but don’t let the weight fool you — those layers are designed to perform at the highest intensity. That, mixed with strategic ventilation that gets cool air to high-heat zones, keeps you fresh from the first rep to the last.

Whatever the season, whatever the weather, there’s a layer for it. Eastbay has all the gear you need for your indoor and outdoor workouts, and you can get it in any color. Get ready to train your way.
