Best Underwear for CrossFit

We spend so much time making sure we have the perfect clothing and shoes for CrossFit training, but what about your underwear.

Having comfortable underwear that flexes with you and absorbs moisture is just as important as your clothing for CrossFit.

So, in this article, we will look at the best underwear for CrossFit training.

Choosing the Right Underwear for CrossFit Training

The best underwear for CrossFit training or any workout routine, for that matter, will be made of either cotton or a synthetic blend with moisture-wicking technology.

Keep in mind that you also need underwear that stretches and flexes with you when you move and conforms to your natural shape. Hence, flexibility is necessary, which can be obtained by adding spandex, lycra, or elastane to the blend of fibers in the underwear.

Choosing Underwear for CrossFit Training

Ultimately finding the perfect underwear for CrossFit workouts adds to your personal preference in what styles you would like to wear. However, there area few components to consider;

  • Coverage – Coverage depends mostly on what feels more comfortable for you. Generally, I would go for a happy medium when it comes to coverage, as too much coverage may cause bunching up and even wedge when you ate performing intense workouts. However, too little coverage can also be quite uncomfortable. Basic bikini-style underwear for ladies and basic briefs seem t be the preferred style when it comes to coverage.
  • Seams and Tags – Friction is an issue in working out and underwear. Therefore, you want something that has no-show or no seams and flat waistbands that will not chafe or dig into your skin. Also, look for tagless underwear options.
  • Materials – As mentioned before, you definitely want either cotton or a mmoisture-wickingtechnology synthetic material,which are your best options. Lycra, elastane, or spandex can be added for stretchability.

Crossfit Underwear

  • Materials – For CrossFit you want underwear that breathes well, wicks away moisture and that will not irritate your skin. In most sports brands there are may technologies used in their materials that provide moisture wicking and drying capabilities. Polyesters and polyester cotton blends can be modified to keep you dry and comfortable. Other materials may include cotton, lycra, and spandex as well as blended options.
  • Design – A comfortable underwear for CrossFit needs to be free of irritating tags, seams, and stitching details, with an almost seamless design. They need to stretch and fit well and be flexible enough to move with you and not restrict movement.
  • Fit – Look for a fit that is snug and comfortable without squeezing or being too tight around your waist and legs. You can opt for boy shorts, briefs, or bikini design underwear, which are usually the most comfortable. I do not recommend thongs or G-Strings, which may not offer the most comfortable fit for cross-fit training.
  • Options – As you will see, there will be many color and print options in underwear for CrossFit training, as well as plus and standard sizes. These all rely on the specific brand that you choose.
