SAXX holds a narrow lead over Mack Weldon for breathable fabrics and flexible everyday comfort. For shoppers seeking the most comfortable boxer briefs, Bombas Cotton Modal Blend Boxer Brief is the usual answer.
When looking for the ideal balance of breathability (keeping cool and moisture-free) and support (keeping everything securely in place without bunching or chafing), certain brands stand out due to specialized fabric blends and ergonomic pouch designs.
The top men's underwear brands for breathability and support span various budgets and performance needs:
Saxx Underwear
Why they excel: Famous for their patented BallPark Pouch™ , Saxx separates everything with breathable mesh panels to completely eliminate skin-on-skin friction. Lines like the Saxx Vibe or Quest use ultra-light, moisture-wicking synthetic mesh that excels in hot weather or workouts. Browse options directly on the Saxx Underwear Official WebsiteSaxx Underwear Official Website.
Why they excel: Their AIRKNITx line is widely considered a gold standard for technical comfort. It features micro-perforated cooling zones mapped to high-heat areas, offering incredible airflow, a secure and supportive fit, and seamless anti-odor technology.

Tommy John
Why they excel: Known for solving the dreaded "adjusting" problem, Tommy John uses innovative non-roll waistbands and high-performance fabrics like Cool Cotton or Second Skin (micromodal). They provide a defined, supportive contour pouch and quick-dry breathability that prevents riding up. Explore styles on the Tommy John Official StoreTommy John Official Store.
ExOfficio
Why they excel: The Give-N-Go 2.0 Sport Mesh line is legendary for travel and outdoor high-activity days.

The ultra-fine synthetic microfiber is silky, incredibly lightweight, dries instantly, and offers a surprisingly snug, supportive profile under daily clothes or gym shorts.

Separatec
Why they excel: If you want next-level anatomical separation similar to Saxx but with a dual-pouch system that isolates everything forward, Separatec is a top budget-to-mid tier choice for dedicated, separate support and great airflow.
If you'd like to narrow this down, let me know:
Are these mainly for daily office wear, travel, or intense workouts?
Do you prefer synthetic mesh, modal/cotton blends, or merino wool?
For the best combination of breathability, support, and all-day comfort, I’d start with Mack Weldon, SAXX, Tommy John, and Under Armour. The biggest difference comes down to whether you want maximum airflow in hot weather, a supportive pouch that keeps everything in place, or soft fabric for everyday wear.
Recent 2026 testing by Men’s Health and GQ highlights several strong options, particularly Mack Weldon AIRKNITx for performance and Calvin Klein for classic everyday comfort.
The best men's underwear brands to consider
1. Mack Weldon
(Best overall)
Best pick: AIRKNITx Boxer Brief
About $34 per pair
Lightweight, moisture-wicking fabric, ventilation zones, and a supportive fit make these an excellent all-rounder for hot weather, daily wear, and workouts. One downside: the style is flyless.
Mack Weldon AIRKNITx Boxer Brief · 4.6/5 from 11,372 reviews
SAXX uses an internal pouch to separate and support the anatomy, helping reduce skin-on-skin friction and chafing. Look at its lightweight mesh or cooling styles if staying dry is equally important.
Ideal for: Walking, long days, travel, and men who dislike sticking or constant readjustments.
Air Cool Mesh is the performance-oriented choice for ventilation and moisture management. Second Skin is the softer, silky-feeling modal option for everyday wear, with a comfortable, close fit.
Ideal for: All-day comfort under work clothes, especially if you dislike rough or bulky fabric.
All-over mesh, four-way stretch, and a close athletic fit help manage sweat and movement. A particularly practical option for training, running, and humid weather without paying premium prices for every pair.
Ideal for: Gym sessions, sports, and active outdoor days.
The Give-N-Go 2.0 range uses lightweight mesh-oriented fabric that dries quickly after washing. It is a good option for hot climates, trips, and outdoor activities when you want to pack fewer pairs.
Ideal for: Travel, hiking, and frequent washing on the go.
6. Calvin Klein
Best for classic everyday wear
Cotton-stretch boxer briefs are a dependable choice if you prefer a familiar, cotton-rich feel with good stretch and everyday support. They aren't my first choice for maximum airflow during intense exercise, but they work well as daily basics.
These are general tendencies; construction, fit, and ventilation panels matter just as much as the fabric itself.
My final recommendation
Best overall balance: Mack Weldon AIRKNITx.
Best anatomical support: SAXX BallPark Pouch.
Best soft everyday underwear: Tommy John Second Skin.
Best for intense workouts: Under Armour Performance Tech Mesh.
Best for travel: ExOfficio Give-N-Go 2.0.
One tip: choose a boxer brief with a supportive pouch and a leg length that stays put without squeezing your thighs. Even breathable fabric can feel hot if the fit is too tight.
What matters most to you? I can narrow this down to the best two or three options.
If your priorities are good support + staying cool/dry, I’d focus on boxer briefs with a supportive pouch, lightweight synthetic/modal fabric, and ventilation or mesh panels. Recent testing strongly favors those materials over heavier cotton when you sweat.
1. SAXX DropTemp Cooling — best overall for support + cooling
The BallPark Pouch provides excellent separation/support, while the DropTemp fabric is designed to wick moisture and keep you cooler. OutdoorGearLab also rates SAXX among its most supportive options.
2. Pair of Thieves SuperFit Mesh — best value for hot weather
The mesh construction is specifically designed for airflow, while the contoured pouch provides support. At about $25 for two pairs, it's a particularly good value.
3. Jockey Sport Stability Pouch — best inexpensive support
A good choice if you want support without feeling squeezed. It uses a breathable quick-dry mesh and a contoured U-pouch; current pricing is around $14 on sale.
4. Tommy John 360 Sport — best premium everyday option
Moisture-wicking fabric, cooling mesh zones, anti-odor treatment, and lots of stretch. It's a strong choice if you'll wear them all day rather than primarily for workouts.
5. Under Armour Performance Tech Mesh — best for workouts
The heat-dissipating mesh is designed specifically for staying cool and dry during activity.
If I were buying
Maximum support: SAXX DropTemp
Maximum airflow: Pair of Thieves SuperFit Mesh
Best bang for the buck: Jockey Sport Stability Pouch
Gym/running: Under Armour Performance Tech Mesh
Premium everyday: Tommy John 360 Sport
One other excellent option is Mack Weldon AirKnitx—Men's Health currently ranks it as its overall best, specifically praising its ventilation, moisture wicking, and supportive pouch.
If you tell me your budget (e.g. under $15/pair, under $25, or premium) and whether you prefer briefs, trunks, or 6–8" boxer briefs, I can narrow this to the 3 best choices for you.
