How we test the best moisture-wicking underwear

Kieran 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.

Rest assured: his rigorous testing process is designed to bring you the best of the best.

1. CXP Endurance XP Shorts

Men’s Fitness verdict

The near-seamless design and multi-panel waistband make these a seriously comfy pair of shorts even over long endurance sessions. If you put serious traing hours in, you want to be in these.
Pros
  • Mildly compressive
  • Bonded anti-chafe seams
  • Excellent durability
Cons
  • Fairly expensive
Materials: 70% nylon, 30% elastane

The CXP Endurance XP shorts are more baselayer-style compression shorts than workout boxers, so offer mild compression benefits as well as superb support and comfort. Bonded seams mean zero chafe risk and a multi-panel waistband spreads pressure out evenly.

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.
Pros
  • Unique BallPark pouch support
  • Selection of leg lengths
Cons
  • Slightly scratchy waistband
  • Can struggle to move sweat
Materials: 85% nylon, 15% elastane

For dynamic workouts, Saxx’s trademark BallPark pouch means everything stays put no matter how much you move in these Kinetic shorts. That means no rubbing or chafing even during all-out cardio efforts, helped by numerous flatlock seams and good sweat-wicking performance.

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.

8. Crossfly Pro 7

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.
Pros
  • Mesh panels boost breathability
  • Silky smooth comfort
Cons
  • Support doesn’t quite match the best on test
Material: 85% polyester, 15% spandex
Colour:Black/blue, black/silver
Sizes:Small – 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. And as March is Prostate Cancer Awareness month, Crossfly is donating £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.

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.
