Related Expert Advice articles

Maybe your significant other always bought your undergarments for you, or maybe you’re just ready for a change. Finding the perfect underwear can be a challenging task– with so many styles, materials, and brands to choose from, it can be overwhelming. We've put together a comprehensive guide to help you find the best underwear for your needs.

Types of men's underwear

  • Boxer Briefs: Just like the name suggests, boxer briefs are a hybrid between boxers and briefs. They provide more coverage than briefs, but are still form-fitting like boxers. They’re a popular choice for men who want the best of both worlds.
  • Boxers: Boxers are the most traditional style of men's underwear. They have a looser fit than briefs and provide maximum breathability, so they’re a good option if you prefer a more relaxed fit.
  • Briefs: Briefs are the most form-fitting style of men's underwear. They provide support and lift, but they’re not always the most comfortable. They’re a good choice for men who like a snug fit.
  • Trunks: Trunks are a shorter version of boxer briefs. They provide less coverage than boxer briefs, but are still form-fitting for a sexier look.

Materials

When choosing mens underwear, consider the following materials:

  • Cotton: Cotton is a popular choice for men's underwear because it’s soft, breathable, and easy to care for. However, it is not as durable as other materials and can lose its shape over time.
  • Microfiber: Microfiber is a lightweight and breathable synthetic material that’s more durable than cotton and can withstand frequent washing.
  • Modal: Modal is a type of rayon that is made from beech tree pulp. It’s soft, breathable, and has moisture-wicking properties. It’s great if you want a comfortable and lightweight material.
  • Nylon: Nylon is a synthetic material that is lightweight, durable, and moisture-wicking. Like microfiber, it’s a good choice if you need a material that can withstand frequent washing.
  • Spandex: Spandex is a synthetic material that provides stretch and support. It’s often blended with other materials to create form-fitting underwear.

How to choose the perfect pair

When choosing the perfect pair of underwear, there are a few things you should consider:

Comfort: Comfort should always be your top priority when choosing underwear. You’ll want to choose a pair that feels good against your skin and doesn't cause any irritation.

Fit: Remember that the fit of your underwear can affect how comfortable it is. You want to choose a pair that fits snugly without being too tight or too loose.

Style: Your underwear style is a personal preference– choose a style that makes you feel comfortable and confident.

Durability: For daily use, it’s a good idea to choose a pair of underwear that is durable and can withstand frequent washing.

Care and maintenance

Proper care and maintenance can help extend the life of your men's underwear and ensure optimal comfort and support. Here are some tips on caring for and maintaining men's underwear:

  • Follow the care instructions on the label. Different materials may require different washing and drying methods.
  • Wash in cold water to prevent shrinking or damage to the elastic waistband.
  • Avoid using bleach or fabric softener, as these can damage the fabric and reduce breathability.
  • Hang dry or use a low heat setting in the dryer to prevent shrinkage and damage to the elastic.
  • Replace underwear that’s become worn out, stretched out, or no longer provides adequate support.
