The bike-short style compression that helps you feel dry and supported from warm-up to cooldown.

What sets the Nike Pro apart from the Under Armour option is smoother, more uniform compression, which serious athletes tend to prefer. Nike builds these as true compression shorts, not boxer briefs. The ultra-tight fit acts like a supportive second skin, which helps reduce muscle vibration during squats, sprints, or cycling. The lightweight fabric is made with at least 75% recycled polyester fibers, so you get performance without the environmental guilt. Nike claims they help keep you feeling dry, cool, and supported from warm-ups through cooldowns — and buyers report the material holds up well wash after wash without losing its stretch or shape.

Unlike the Under Armour shorts below, these do not have a designated Drop-in Strength Pocket. They make up for it with a smoother, more uniform compression feel. The stretchy design helps you move at full intensity during your toughest workouts or competitions. The relatively simple packaging (1 x 1 x 1 inches at 1 ounce) reflects that the shorts themselves are the main event.

One trade-off to expect: the compression fit is very tight. If you prefer a looser feel or need a fly opening, these are not the pick. They work best as a dedicated base layer under shorts or tights during high-output sessions. If a fly matters to you, the New Balance boxer briefs are a better match.

The original performance baselayer that wicks sweat so fast you barely notice it.

Under Armour claims this is “the one you put on first and take off last,” and the specs back that up. The HeatGear fabric blend of 84% Polyester and 16% Elastane, versus New Balance’s 90% Polyester and 10% Spandex, means these shorts are stretchier and more form-fitting than a standard boxer brief. That extra elastane gives you a truly second-skin compression fit that stays in place during everything from sprints to heavy deadlifts. Strategic mesh panels add ventilation exactly where you need it most, while the ergonomic design keeps seams away from high-abrasion areas to prevent chafing.

Buyers consistently point to the Drop-in Strength Pocket on the right side as a surprisingly useful feature — you can stash a phone or a key without any bulk. The 6-inch inseam gives solid mid-thigh coverage without riding up. One owner mentioned that after dozens of washes, the waistband still holds its stretch and the fabric has not pilled, which is a strong sign of durability.

The catch? No fly. And the compression is ultra-tight by design — if you are not used to a snug fit, these will feel restrictive at first. They are built as a performance baselayer, not a casual lounge pair. For all-day comfort with a fly, the New Balance set is a better call.

The three-pack boxer brief that blends breathability with a no-chafe ride for daily wear and light training.

The main reason to pick New Balance over the compression options: a functional fly opening. New Balance uses a 90% polyester and 10% spandex blend (rated at 150GSM, which means grams per square meter, a measure of fabric weight — lower GSM is lighter and more breathable) to create a fabric that feels lightweight and stretches in all directions without binding. That 10% spandex gives you 360-degree stretch for unrestricted movement, but it is a less aggressive compression feel than the Under Armour’s 16% elastane — so you get a comfortable, standard fit rather than a squeezed-in compression. The wide, soft jacquard elastic waistband with logo detailing keeps the shorts in place without digging into your skin, which buyers consistently praise as a comfortable all-day feature.

The fly is a major plus if you need quick bathroom access without peeling everything off — something the compression shorts in this list simply cannot offer. The no-chafe flatlock stitching is another smart detail; owners mention that even after long runs or full workdays, the seams do not leave red marks. At 250 grams for a three-pack, the set is remarkably light, and the 6-inch inseam provides coverage that stays put during leg movements.

The main trade-off is that the fabric is not as sweat-wicking as the Under Armour HeatGear. For light to moderate activity, it works great. For soaking-wet HIIT sessions, the compression styles above handle moisture faster.

The micro modal boxer brief that feels softer than cotton while still moving with you.

The budget-friendly move: for about the same price as one compression short, you can refresh your entire drawer. This is the outlier in the lineup because it swaps the usual polyester for 90% Micro Modal — a fabric made from beech tree pulp that is known for being exceptionally soft and breathable. The 10% spandex blend still gives you four-way stretch, so the shorts move with you during activity rather than restricting you. The contoured pouch and soft waistband are built into the design for support and comfort, and the fabric is labeled “quick dry,” which helps manage moisture better than pure cotton.

Buyers who picked the 6, 8, or 10-pack option consistently mention the value: you get a full drawer refresh at a cost per pair that undercuts most competitors. One reviewer noted that after several months of washing and drying, the fabric has not pilled or lost its stretch, which is an important durability sign for a budget-friendly multi-pack. Unlike the New Balance pair, this one does not list a specific inseam length in the data, so the coverage may vary depending on sizing.

The real limitation is that Micro Modal does not wick moisture as aggressively as polyester. For light activity or daily casual wear, it is incredibly comfortable. For heavy, sweat-drenched workouts, the synthetic blends in the Under Armour or Nike options handle sweat faster and more effectively.

The classic jock strap that brings old-school support and breathability for high-impact sports.

For high-movement sports like basketball or soccer, the open air flow of a jock strap beats any boxer brief. GOLBERG G lets you bypass standard underwear altogether with a dedicated jock strap. The open knit pouch is made from 96% Polyester and 4% Spandex, which means it breathes well and moves with you without trapping heat. The 1-inch leg bands and the 3-inch waistband (sitting around your mid-waist) are built with 88% Polyester and 12% Plant-Based Rubber, giving the straps a natural elastic feel that holds firm without synthetic stiffness. The waistband maintains its shape after repeated uses and washes, according to the product specs, which is essential for a jock strap that needs to stay tight through a game.

Unlike every other product in this list, this is a strapped supporter rather than a short, so there is zero thigh coverage. That makes it cooler and less restrictive for sports like basketball, soccer, or martial arts where you want freedom of movement. The sizing runs from Slim Small (24-28 inches) all the way up to XX-Large (50-58 inches), so finding the right fit is easier than with one-size options. Buyers who have used traditional supporters for years say the build quality and elastic hold up well even after seasons of use.

The obvious limit: if you have never worn a jock strap, the leg straps and open design take getting used to. And there is no cup pocket built into this model — it supports, it does not protect from impact. For that, you would need a cup-specific supporter.
