2. Saxx Kinetic

Men’s Fitness verdict

If you value support above all else, these Saxx Kinetic shorts will do the trick. In 5-inch and 8-inch versions, they’re a great choice for the most dynamic of workout sessions.

  • Selection of leg lengths
  • Slightly scratchy waistband
  • Can struggle to move sweat
Materials 85% nylon, 15% elastane

We found the long 8-inch inseam gives them a baselayer-like feel, with plenty of stretch without losing their shape. For those that prefer a boxer-style brief there’s also a shorter 5-inch version. If you want moisture-wicking underwear to tackle box jumps, burpees and sprints, look no further than the Saxx Kinetic.

We appreciate And Then’s support of charity movement Movember, donating 50% of its profits to help change the perception of men’s mental health and shed light on testicular as well as prostate cancer. But ultimately it’s the company’s Bamboo Boxers that do the supporting.

9. Crossfly Pro 7

Product shot of CrossFly boxers

Men’s Fitness verdict

It might take a while to get used to the X-fly pouch but the satin-soft comfort benefits are immediate. Breathability is one of the best on test too, though support could be better.
  • Mesh panels boost breathability
  • Silky smooth comfort
  • Support doesn’t quite match the best on test
Materials 85% polyester, 15% spandex
ColorsBlack/blue, black/silver
SizesSmall – XXL

We’ve worn these Crossfly Pro 7 pants for day-long outdoor adventures and short HIIT blasts in the gym and they cope admirably with both – and anything in between. The 7-inch legs won’t ride up, however dynamic your workout, though support isn’t quite as locked-in as some. But breathability is first-class thanks to strategically placed mesh panels.

They might be a little on the pricey side, but buying three-packs cuts the cost a little. Every March (Prostate Cancer Awareness month), Crossfly donates £10 to Prostate Cancer UK for every pair sold – so you can do your bit for a worthy cause while enjoying their soft and silky support.

How we test moisture-wicking underwear

Kieran and Laurence put these sports boxers through their paces in a range of workouts, from gentle jogs to sweaty sessions, testing them in terms of fit, comfort, support and durability. They also paid special attention to how well the fabric wicked moisture from the skin, alongside any additional high-tech features such as four-way stretch and anti-chafe seams. Rest assured: their rigorous testing process is designed to bring you the best of the best.

Benefits of moisture-wicking underwear for men

When it comes to working out, your underwear may not be the first thing on your mind. But chafing, discomfort and a lack of support are not what you need when you’re working hard. That’s why investing in a good pair of sports boxers or moisture-wicking underwear is a smart move. 

Sporting the right pair of pants during your sweat sesh not only offers superior comfort and support, but moisture-wicking materials like polyester, nylon, polyamide and merino wool keep you cool and dry, cutting your risk of chafing and irritation.

Some longer baselayer-style briefs even offer compression for targeted support for your muscles, improving circulation and reducing fatigue.

What the experts say about moisture-wicking underwear for men

We talked to athletes and coaches about what they look for in moisture-wicking underwear. Jake Dearden, HYROX master trainer and 247 Represent head coach and athlete, says: “I like the trunk-style underwear whilst running as this stops chafing of the thighs.”

Jonny Mellor, New Balance athlete and online running coach, adds: “It’s important to pick underwear that fits well and offers moisture wicking technology with a breathable fabric to help you keep cool and dry.”

Finding your fit

Then there’s fit. Sports underwear is designed to move with you. Whether you’re running, jumping or lifting weights, the last thing you want is to be constantly adjusting your boxers mid-set. With a snug fit and stretchy material, sports underwear stays put without feeling restrictive, so you can focus on your workout without distractions – or wedgies. 

And let’s not forget about hygiene. Sweaty, damp underwear is a breeding ground for stink-making bacteria. Some sports underwear features antimicrobial fabrics that combat odour. Though you’re still going to need to wash them regularly and the best workout smalls survive multiple spin cycles without losing their shape.
