That annoying moment when your underwear creeps up mid-stride isn’t just uncomfortable, it’s completely avoidable. If you’ve been searching for men’s long-leg underwear that actually stays put, you’re not alone. Blokes across Australia are ditching their traditional boxers and briefs for longer-cut options that promise no more ride-up or bunching.
The difference comes down to design. Longer legs create more fabric contact with your thighs, which means better grip and less migration throughout the day. Whether you’re at the office, hitting the gym, or travelling, the right pair keeps everything in place without constant adjustments.
We’ve rounded up five of the best long-leg underwear options available, including our own SLY Collective bamboo boxer briefs with their unique inner pouch design. Each pick has been chosen for its ability to deliver genuine all-day comfort without the creep.
1. SLY Collective bamboo long-leg boxer briefs
SLY Collective’s bamboo boxer briefs stand out in the mens-long-leg underwear category with a design focused on eliminating the exact problems you’ve been dealing with. These aren’t just standard long-leg boxers with extra fabric. You get purpose-built underwear that combines anti-chafe technology with genuine ride-up prevention through thoughtful engineering.
What makes them different
The standout feature is the built-in inner pouch that physically separates and supports everything down there. This design prevents skin-on-skin contact, which is the main culprit behind chafing during movement. Your anatomy sits in its own dedicated compartment, meaning less friction and zero bunching throughout the day. The bamboo fabric itself brings natural temperature regulation, keeping you cooler than synthetic blends or traditional cotton options.
Comfort and anti-chafe design
You’ll notice the pouch design working within the first hour of wear. Instead of everything pressing together and creating friction points, the inner support system keeps things separated and comfortable. Bamboo’s natural properties help wick moisture away faster than cotton, which means less sweat buildup in areas prone to chafing. The fabric stays softer against your skin even after multiple washes, maintaining that initial comfort level without becoming rough or stiff.
"The built-in pouch eliminates the constant readjusting most blokes deal with daily."
Fit, leg length, and sizing notes
The longer leg design extends further down your thigh than standard boxer briefs, providing additional coverage without restriction. This extra length creates the grip needed to prevent ride-up during walking, sitting, or exercise. Sizing runs true to Australian standards, and the bamboo blend offers natural stretch that adapts to your body without losing shape. If you’re between sizes, consider going with your usual fit rather than sizing up.
Best for
These work brilliantly if you experience regular chafing, need all-day comfort during active work, or simply want underwear that doesn’t require constant adjustment. The combination of pouch support and longer legs makes them particularly effective for blokes with larger thighs or those who’ve struggled with traditional boxer brief designs riding up.

2. Knobby long trunks
Knobby delivers affordable long-leg options that focus on practical comfort without unnecessary frills. Their trunks prioritise everyday wearability through simple design choices that work for most body types. You get solid basics that handle the essentials well.
Fabric options and breathability
Knobby uses cotton-rich blends in their long trunk range, typically combining cotton with elastane for stretch and recovery. This mix provides decent breathability for daily wear, though you might notice more heat retention compared to bamboo or performance fabrics during intense activity. The material softens with washing and maintains reasonable durability through regular use.
Leg length and ride-up control
The extended leg design sits mid-thigh, offering enough coverage to prevent most ride-up issues during normal movement. Your thighs get adequate grip without the fabric digging in. The longer cut works effectively for reducing bunching if you’re dealing with standard office or casual activities.
Fit, sizing, and waistband feel
Sizing follows typical Australian standards with a comfortable waistband that sits firmly without excessive tightness. The elastic holds position throughout the day without rolling or creating pressure points. Fit runs true to size for most blokes.

Materials and sweat management
Tradie uses cotton-polyester blends engineered for Australian heat and hard work. The fabric mix pulls sweat away from your skin faster than pure cotton, helping you stay drier during extended physical activity. This combination maintains breathability while offering better moisture wicking than traditional cotton options.
No-chafe focus and long-leg coverage
The longer leg design extends well down your thigh, creating enough surface area to prevent ride-up during movement. Flatlock seams sit smoothly against your skin, reducing friction points that cause chafing. Your thighs get proper coverage without restriction, keeping everything in place during bending, lifting, or walking.
