A one-of-its-kind pair of sweatpants built with the same fabrics and technology as the best-seller Reversible Hoodie. Engineered to withstand the most brutal environments and keep you warm (or fresh!) on those lazy days. A three-layer construction allows them to protect you against the elements and perform as two completely different pairs of pants in one. 

On one side is a soft graphene-integrated fleece that will keep you warm no matter what. In the middle, a futuristic membrane that combats the elements and, on the other side, a proprietary nylon-based fabric that will keep you fresh when it's baking hot.

The Reversible Sweatpants make the absolute best match for the Reversible Hoodie from our Future Series.

Why make them reversible?

To achieve these key points:

1. That it protects you against the elements (heat, cold, rain, wind, snow).
2. Extreme levels of comfort (an uncomfortable pair of sweatpants is as good as diet water).
3. That it could last a lifetime.
4. That is was so versatile you could use it all year long.

Graphene-integrated fleece

Graphene is not only the strongest material on Earth, but it’s also the lightest. On top of this, it has other marvel-hero-like properties: It’s hydrophobic, bacteriostatic, flexible, it’s almost completely transparent and it emits a Far Infrared Wave (energy) incredibly similar to the one emitted by the human body, meaning its superb at retaining heat when it’s cold and to keep you fresh when it’s hot.

This is the material we are empowering the fleece of the Reversible Sweatpants. Excited? You should.

Beating the cold

On one face, the Reversible Sweatpants features a Graphene-integrated grid fleece which, when worn on the inside, will keep you warm even in the coldest conditions. Graphene excels at radiating heat, and it's Far Infrared (FIR) radiation profile is almost identical to that of the human body. That means the Reversible Sweatpants are exceptionally efficient at accumulating and retaining heat. Also, due to the bacteriostatic properties of Graphene, they will fight with no mercy the bacteria that causes clothing to smell.

Beating the heat

On the other face, we integrated a state-of-the-art Nylon-based Ruco-therm fabric developed by the German manufacturer Rudolf. This fabric boosts long-term evaporative cooling with a depot effect. The fabric is incredibly soft to the touch and feels like nothing you have ever touched before. These sweatpants will keep you cool and dry even in the hottest conditions.

Ultra-high performance membrane

Now, the thing is that we face not only cold and hot climates but also rainy, snowy, and windy settings. The only way to combat them as well was to integrate an ultra-high performance membrane (which is sandwiched in between the other 2 fabrics). To achieve this, the fabrics undergo a heat process so they feel like one heavy-duty fabric.

Rain and wind will remain out

The membrane used here is hydrophobic but also incredibly breathable as it allows moisture vapor to escape flawlessly. Even though this membrane is classified as a 10k waterproof membrane (Hydrostatic head test), we define the Reversible Sweatpants as a highly water-resistant pair of sweats. 

This is because of the reversible nature of the pants as it would be impossible to tap the seams on the fleece side. Nevertheless, the Reversible Sweatpants will keep your bone dry in most situations.

Storage (a.k.a. pockets!)

You can always use that extra pocket, right? On the Reversible Sweatpants you get two main frontal zippered pockets plus an also zippered back pocket.

All pockets use YKK's invisible zippers for minimalist aesthetics.

These pockets are accessible through either side of the sweatpants so no matter if facing cold or warm climates you'll get plenty of storage to secure your goods.

4-way stretchable and built to last a lifetime

A pair of sweatpants need to stretch. Comfortability relies on this…badly! This peak-performance Reversible Sweatpants stretch in a way that you would never imagine you are wearing a 3-layered membrane-integrated fabric.

Less stuff, but better stuff. This is part of our mission - and follows through into our guarantee terms. We work with the toughest material on Earth, with top-notch elements and with the best manufacturers in the world. Being the best and toughest in anything comes with responsibilities. Our apparel is guaranteed for life.

A heavenly match for the Reversible Hoodie:

The Reversible Sweatpants come as a set extension of our best-seller Reversible Hoodie. The same fabrics technology and materials are used to engineer probably the most advanced pair of sweatpants.

  • Why did we make them reversible?
  • Because at Graphene-X versatility is a key value. Having one piece of clothing that can perform as two really nails this point. While wearing it on one side will keep you warm and toasty on the other side it’ll keep you a couple of degrees fresher than a normal pair of sweatpants.

  • What sweatpants material is considered the warmest?
  • There are a few materials used for sweatpants, but some are warmer than others. One option is thermal sweatpants. In this case we empower them with a special material that helps to trap heat, making them great for chilly weather. Additionally, some sweatpants are lined with fleece or soft fabric, which can also help keep you warm. Graphene is the material we use to make our Reversible Sweatpants extremely warm from one if its sides.

  • Is there a difference between clothing that’s waterproof and one that’s water-resistant?
  • Water-resistant clothing is made from materials that can resist some water, but they are not entirely waterproof. On the other hand, waterproof clothing normally sports a membrane that inhibits the water from leaking through the fabric. This pair of sweatpants feature a fully waterproof membrane but due to the reversible nature of it we rate them as a highly water-resistant.

Graphene - X

I wore this with thermals under together with the Reversible hoodie and walked through medium-hard snowfall in Japan and I was bone dry inside. Not a full replacement for snow pants but will definitely work in pinch! Pockets with zippers are definitely a plus and were also protected from the weather.
