Best Slim Fit Boxers

Blade + Blue Boxer Shorts

Blade + Blue is incredibly dedicated to making their products in the USA (San Francisco, specifically). We spoke with the owner Peter Papas about what he loves most about making his products in the U.S.: “I choose to make products in the USA because it is very important for me to have a personal relationship with the people who are making products for Blade + Blue…I think the most important aspect is that we look out for each other. We can easily voice concerns, make sure both parties are treated fairly & there is a deeper sense of care that I can see in the finished product.” Most boxers are saggy, but the Blade + Blue Boxer Shorts offer a slim, sleek, and sexy fit that’s anything but typical with boxers. We love how this product hugs right against your body, but still allows you to move around freely. The boxer shorts are made of a mix of cotton and lycra, ensuring that they are breathable, but also making them nice and flexible. They come in several different colors and are sized for an exact fit. We really enjoyed the dual button closure included on these shorts that give you a slightly more customizable fit when putting them on. Our only complaint is the slightly tight legs. Those with larger thigh muscles and a thin waist may have trouble getting them to fit properly.

They are available in sizes ranging from small to XXL and should fit most.

They’re made from organic cotton jersey and designed with a tagless label for maximum comfort. These heavily stitched briefs are durable, but silky smooth at the same time. They are available in sizes ranging from small to XL and in Black and Wood color finishes. We love that the whole manufacturing process for BGreen Organic Cotton Briefs occurs in a family-owned factory within the United States. These briefs are also made from certified organic cotton and a special process is used to limit the energy and water used during the creation of these undergarments. If you’re searching for sustainable men’s underwear, these briefs are an excellent option.

Best Stay Cool Underwear

RibbedTee G3 Men’s Boxer Brief

For performance use, the RibbedTee G3 Men’s Boxer Brief was our top pick. We added this underwear to our list because they are made from a cooler material than cotton, but still wick moisture away and offer a comfortable fit for long-term use. They are made from a mix of nylon and synthetic materials and have just the right level of stretch for a snug form-fitting hold. They feature a pouch for added comfort up front, and are designed with a low-profile waistband that has excellent stretch for a good hold. These boxer briefs are also tag-free and offer real odor resistance. You’ll smell better and feel better with these on compared to more traditional boxer briefs and we really enjoyed testing these out. RibbedTee also did a really good job educating us about their products, which is something they say that their customers love about them most. We also spoke with the RibbedTee founder, Mike Schwarz, on why he chooses to manufacture in the USA: “We’re committed to building long-term partnerships with our local Los Angeles-based manufacturing partners, who are in many cases family-run boutique businesses themselves. As we grow, they grow.”

These long johns fit snugly in place, and they feel lightweight while offering some added warmth. We love the way these fit and hold throughout the day and experienced real comfort during use without any itching. These long johns are machine washable and dryable and easy to maintain. They also naturally resist odors, making them more pleasant to wear over time. They are costly, but are an excellent investment for warmth during cold months in northern climates.

Recap: Best Men’s Underwear Made in the USA

Factors We Considered


Underwear, just like t-shirts or any other article of clothing, sees a lot of wear. Each time that you twist and turn you will be flexing and bunching up the material. Good men’s underwear should be made from a durable material that’s going to hold up well over time and won’t tear. We prefer cotton blended with spandex or other synthetic fibers, but you must also pay close attention to the stitching at the seams. Heavily stitched underwear holds up better over time. The best underwear doesn’t suffer from much piling after washing. Always pay attention to wash and dry directions for your underwear before caring for them to make them last as long as possible.


Your underwear comes in contact with some of the most delicate parts of your body, so they should be comfortable. Underwear that’s made from soft materials like cotton or silk will feel best against your sensitive areas. We prefer cotton in this section as well for its soft feel while remaining durable and breathable, but some synthetic fabrics and fibers work well too.


While you might not be showing off your underwear all the time (unlike your socks), chances are good that you still want them to look their best. We look for a nice snug fit that will conform to your body well. Most of our top recommendations are traditional solid colors or patterns, but you can feel to go with prints and other styles if you really enjoy them. Make sure that you like the look of your underwear though, otherwise, you won’t want to wear it as much.


Good underwear is highly breathable, which will help you remain comfortable during use. Synthetic fabrics like silk tend to trap moisture, which can lead to discomfort and bad smells over time. Highly breathable material like cotton is best to help you remain comfortable over time.

Size Selection

All of our top recommendations for the best men’s underwear made in the USA offer a good range of sizes to pick and choose from. Different men have different body shapes, and what fits you well might not fit your friend the same. Choosing underwear that’s going to fit your body as perfectly as possible will ensure enhanced comfort, which is why we value size selection.


Even top-quality underwear can’t be too expensive or you’ll never want to purchase it. We looked at the value offered by the underwear when choosing our top recommendations to make sure you’re getting the best underwear for your money. Shopping for your spouse?
