Our Top Picks
Best Overall: Saxx Vibe Boxer Briefs
When it comes to Saxx, it’s all about their proprietary Ballpark Pouch, a hammock-shaped pocket on the front-inside of their boxers and briefs that let your boys stay put and prevents any sort of skin-on-skin friction that can create the kind of chaffing you never want to endure. This means you don’t have a fly on the boxers, but that’s a modest sacrifice for the comfort and security they provide.
The Vibe boxer-briefs are part of their daily wear line of underwear, with flat-out seams that have reverse-stitching to place the softer side of the garment against your skin and a nine-panel construction to provide support around the glutes, thighs, quads, and hamstrings for no-slip comfort. The fabric itself is mostly sweat-wicking viscose with five percent spandex for stretch, and they come in a host of color options.
It should be noted as well that all Saxx products come with that signature Ballpark Pouch, from running shorts to long underwear to compression boxers, so if you come to appreciate that pocket, you have a wealth of options.

Best Buy: Sock It to Me Tiki Tush Boxer Briefs
Embrace your love of the tropics by bearing the bold prints of the Tiki Tush Boxer Briefs from sock-and-underwear’s arguably loudest manufacturer, Sock It to Me. Comfort is assured for daily use thanks to the 95 percent cotton fabric, along with a touch of elastane for stretch; you wouldn’t want to wear these while running or trekking (when cotton gets wet, you will get cold and the fabric takes forever to dry), but for more modest travels, they’re wonderful.
The countered, fly-free pouch keeps things in place, while a seamless back and smooth sides keep the shorts from crimping; a cross-grain crotch gusset adds extra stretch. And you can’t beat the mix of tropical images on the boxer briefs, including tiki masks, flowers, palm trees, and hula ladies.
Best for Training: Lululemon Game On Boxer Briefs
Though most associated Lululemon with women’s yoga, their men’s line of apparel made traction in the active and travel set almost from the jump—and the Game On Boxer Briefs illustrates why. They boast a 7.5-inch inseam to provide coverage and support without overdoing it, the optimal length to avoid bunching up under tighter-fitting clothing, with flat seams to reduce unwanted chafing. A soft-to-the-touch Coolmax liner wicks sweat during high-octane activities and helps you endure long waits in hot climates, while the off-center seams running down the glutes assure a no-slip fit when you bend down to retrieve your bag off the luggage carousel.
The color range won’t turn heads—which is probably a good thing, though textured pattern options in gray and black and black and white add a nice touch of flair.
Best for Versatility: Smartwool Merino 150 Boxer Briefs
You might scoff at the concept of wool underwear—but wear one pair merino wool boxer-briefs and you’ll be a convert. This all-natural fabric will keep you cool when you’re hot, and warm when the mercury dips. It wicks sweat and—arguably most importantly—does not retain odors, even after days of continuous use should your travels (or travel style) force that situation. The breathable merino 150 is thin and soft to the touch, built off a core spun technique that wraps the fibers around a nylon thread core for added durability, the typical Achilles heel of thin merino wool.
It comes with a fully functioning fly, a six-inch inseam, and a 40-mm waistband that keeps them in place, with flat-lock seam construction to eliminate chafing. Better still, like all merino wool products, they’re machine-washable (or hotel kitchen sink) safe; just let them air dry afterward.
Best for Comfort: Patagonia Capilene Daily Boxers
If you lean towards the loose and breezy, Patagonia’s Capilene Daily Boxes are destined to become your new obsession. The lightweight poly base layer offers everyday comfort, with ample stretch and a fully functioning fly. Part of the brand’s award-winning Capilene line, they wick sweat and dry quickly and come with Polygiene—a permanent odor control treatment that stands up to countless washes and wear-and-tear. You’ll love the soft, brushed-elastic waistband that won’t bind, roll, or bunch, providing a trim silhouette. We have found, after literally years of use, sometimes the elasticity in the waist can give. But honestly, it’s probably time for a new pair. And Patagonia’s Capilene collection isn’t just in boxers; the fabric carries across all underwear styles, including full-length pairs and boxer briefs.

Best for Tight-Fitting Clothes: Icebreaker Anatomica Briefs
Icebreaker’s Anatomica Briefs fit tightly enough to leave pretty much nothing to the imagination, but if you prefer briefs over boxers or boxer-briefs, they’re tops. The underwear is constructed from a super-soft merino wool blend with core-spun fabric for enhanced durability and just a touch of Lycra for stretch. The merino wicks sweat naturally, keeps you cool on hot days, and doesn’t retain odors over days of unwashed use. A contoured pouch keeps things snug and in place, while the flat-lock seams and an elastic waistband assures that you won’t have to deal with any sort of chaffing. The only potential ding? No fly.
Best for Warm Temps: Ex Officio Give-n-Go Mesh Boxer Briefs
Ex Officio has long held the mantle for award-winning travel underwear, and they took everything that worked well in their signature Give-n-Go Boxer Briefs to new levels with the all-mesh version, making them ideal for hot, sticky climates. The ergonomically designed boxer briefs utilize ultra-light mesh fabrics that breathe like a marathoner and dries quickly. Contrast flat-lock seams pair with a smooth waistband to avoid chafing, and an overall snug fit and a lower rise make them ideal for high-energy outings.
The mostly nylon fabric joins forces with a bit of Lycra spandex for stretch, while an antimicrobial treatment fights off odors, even after legions of washings. They also come with an ergonomic fly panel made of classic diamond weave mesh for solid support. That said, using the fly can take a bit of fuss. Some wearers report bunching in the six-inch inseam models, so if you wear tight pants or shorts or have longer legs, consider going for the ones with nine-inch seams.
Best for Cold Days: Trew Lightweight Wool Bottoms
When it comes to long underwear, merino wool should be your first—and last—option. Unlike cotton or synthetics, which may wick away sweat but may not dry quickly, merino wool keeps you warm in the unlikely event that the fabric gets wet, and cool when things start to heat up. It may cost more, but it’s worth it. And you also get all the other merino properties, including odor resistance, natural wicking, and machine wash-friendly apparel.
Trew’s take on that classic fabric is dubbed NuYarn, which wraps the 17.5-micron fine merino fibers around nylon strands for added strength. The end result? Long underwear that’s 39.9 percent loftier, 35 percent stretchier, 25 percent warmer, and 16 percent stronger than lesser merino layers—and they also drive up to five times faster than ring-spun versions. Double-layered cuffs keep them from riding up, while an articulated butt panel provides freedom of movement in all active scenarios.
