Chafing can turn a workday, long flight or 10km run into a slow burn. Hot Aussie summers, sweat-soaked cotton and seams that rub only make it worse — and short legs that ride up can leave your inner thighs raw by lunchtime. The fix isn’t talc on repeat; it’s underwear designed to stop friction in the first place: longer legs that stay put, flat seams, breathable moisture‑wicking fabrics, and smart pouch support that keeps skin from sticking.
To save you the trial and error, we’ve rounded up eight of the best men’s anti‑chafe underwear you can buy in Australia right now. This line‑up spans bamboo, merino and performance microfibre boxer briefs and running undies — with options from Australian labels alongside global favourites. For each pick, you’ll get why it prevents chafing, fabric and fit notes, who it suits, plus price and where to buy locally. Whether you’re training, travelling or just done with thigh rub, use this guide to find a pair that stays cool, supportive and chafe‑free all day.
1. SLY Collective bamboo pouch boxer briefs
Engineered in Australia and built around a “life‑changing” inner pouch, SLY Collective’s bamboo boxer briefs are purpose‑made to end thigh rub. The structured pouch separates and supports so skin doesn’t stick, while the longer leg stays put to stop ride‑up — a potent combo if you’re hunting the best men’s underwear for chafing in warm Aussie conditions.
Why it helps prevent chafing
The secret is separation and stability. SLY’s built‑in pouch creates space between your anatomy and inner thigh to eliminate skin‑on‑skin friction. Pair that with a longer leg that resists bunching and you reduce the two biggest chafe triggers: rubbing and fabric creep. Bamboo’s natural temperature regulation also helps you stay cooler when the mercury spikes.
- Inner pouch separation: Cuts friction where it starts.
- Longer leg: Helps prevent ride‑up and bunching during movement.
- Cooler wear: Temperature regulation helps minimise sweat build‑up.
Fabric and fit
Cut from soft bamboo, these feel smooth against the skin and breathe well through long days, flights or workouts. The fit is supportive without squeezing, with the pouch offering structured hold and the legs giving confident coverage. A neat bonus is the integrated “nifty pocket” for a key, card or passport — ideal for travel or gym.
- Bamboo comfort: Soft handfeel with temperature regulation.
- Supportive structure: Pouch lift without compression.
- Practical design: Discreet stash pocket adds everyday utility.
Who it’s for
Men who run hot, train hard or walk a lot — and anyone fed up with thigh rub. They’re also a smart pick for travellers who want chafe‑free comfort, discreet storage and all‑day freshness, plus guys mindful of support and temperature for testicular health.

Why it helps prevent chafing

7. Lululemon Always In Motion boxers
A gym favourite that doubles as an everyday anti‑chafe staple, Lululemon’s Always In Motion (AIM) boxers pair a silky, second‑skin feel with reliable support. If you want a pair that disappears under chinos at work, then keeps you cool through squats or a sweaty commute, AIM makes a strong case in any shortlist of the best men’s underwear for chafing.
Why it helps prevent chafing

Final take
