How to Prevent Chafing with the Right Underwear

Quick answer

Most chafing comes from three things: fabric that stays wet, seams that sit where your skin folds, and a fit that bunches or rides up. To prevent it, choose underwear that moves with you, wicks moisture, and has minimal seaming in high-rub zones. If you already have raw skin, treat it first and switch styles before you train again.

Chafing rarely means you did something wrong. It usually means your underwear is doing something wrong — holding sweat, twisting under movement, or sitting exactly where your thighs and waistband meet. The fix is not more powder or tougher skin. It is matching the cut and fabric to how you actually move.

This guide separates the symptom from the cause, gives you a corrective action for each, and tells you when to stop and choose a different option entirely. You will also see how specific TEAMM8 styles map onto common chafing problems, so you can shop with a reason instead of a guess.

Why underwear causes chafing in the first place

Chafing is friction plus moisture. When fabric holds sweat against your skin, the surface softens and rubs more easily. Add repeated movement — running, lifting, cycling, or just a long, hot day — and the same spot gets irritated over and over. The underwear is not always the villain, but it is the layer you can change fastest.

Fit matters as much as fabric. A waistband that rolls, a pouch that shifts, or a leg opening that rides up all create repeat contact points. The goal is a layer that stays put, breathes, and has as few raised seams as possible in the areas where your body naturally folds.

• Sweat left on skin is the biggest multiplier — change out of damp underwear promptly after training.
• Raised seams and thick waistbands are common culprits in the groin and hip crease.
• If chafing only happens in one pair, the pair is the problem, not you.

Match the cut to the friction point

Where you chafe tells you what to change. Inner thigh rubbing usually points to a looser leg opening or fabric that bunches. Waistband irritation points to a thick or rolling band. Pouch-area rubbing often means the front panel shifts during movement. A thong or brief with a stable, minimal waistband reduces bulk, while a bikini brief with an ultra-thin waistband can sit flatter under clothing.

If you are chafing during sport specifically, prioritize a cut that does not need constant adjusting. The less you touch and tug, the less you create new friction points. For some people that is a minimal thong; for others it is a form-fitting brief. Neither is universally better — it depends on where you rub.

• Inner thigh chafing: look for a cut that stays in place and does not ride up.
• Waistband chafing: choose an ultra-thin or low-profile band.
• Pouch shifting: choose a style with a defined pouch that holds position.

Fabric and moisture: what actually helps

Soft, breathable fabric reduces the abrasive edge of friction. Recycled microfibre blends are popular for this because they feel smooth against skin and dry faster than heavy cotton. Cotton-blend rib is comfortable for everyday wear but can hold more moisture during intense activity, so it is often better for low-sweat days than for long training sessions.

There is no single miracle fabric. The practical rule is: the sweatier the activity, the more you want a smooth, quick-drying surface and a fit that stays close without pinching. If a fabric feels rough or heavy when damp, it will likely chafe when you move.

• Test fabric against your inner wrist — if it feels rough dry, it will feel worse wet.
• Avoid thick, raised seams in the groin and hip crease.
• Change out of damp underwear as soon as you can after sport.

When to stop and choose another option

If you have open skin, bleeding, or pain that lasts beyond a day, stop training in that area and let it heal before you test new underwear. No cut or fabric should be worn over broken skin. If chafing continues after you have switched to a smooth, well-fitted option, the issue may be your shorts, your laundry detergent, or a medical skin condition — see a professional rather than buying more underwear.

Also stop if a style requires constant adjusting. Underwear that needs pulling, tucking, or re-positioning every few minutes is creating the friction you are trying to avoid. A good pair disappears under movement. If it does not, it is the wrong pair for that activity, even if it looks right.

• Heal first, then test new styles on short, low-sweat sessions.
• If chafing persists across multiple well-fitted styles, look beyond underwear.
• Constant adjusting is a red flag — return to a simpler, more stable cut.

Chafing diagnosis: symptom, cause, action, stop point

• Symptom: redness and rubbing in the inner thigh: Likely cause: fabric bunching or a leg opening that rides up during movement. Action: switch to a closer-fitting cut with a stable leg line, like a form-fitting brief. Stop if the skin is broken — heal before retesting.
• Symptom: irritation along the waistband: Likely cause: a thick, rolling, or tight waistband creating a repeat contact line. Action: choose an ultra-thin waistband style such as the Flaunt Bikini Brief. Stop if the mark persists after switching — check your shorts or belt next.
• Symptom: rubbing at the pouch or front seam: Likely cause: shifting front panel or raised seams in a high-movement area. Action: try a minimal, seamless style like the Casanova Thong. Stop if adjusting is constant — that pair is wrong for that activity.
• Symptom: chafing only during sweaty sport: Likely cause: moisture held against skin by heavy or slow-drying fabric. Action: choose a smooth, quick-drying recycled microfibre style and change immediately after. Stop if it continues — consider a different short or anti-chafe balm.

TEAMM8 styles that address common chafing causes

• Glide Micro Thong - Onyx: Minimal thong cut with just the pouch and string attached to a 1cm waistband, made from super soft recycled fabrication. The thin waistband and minimal coverage reduce bulk and seam contact, which helps if your chafing comes from a thick band or bunched fabric.
• Flaunt Bikini Brief - Grey Marle: Ultra-thin waistband and form-fitting design in irresistibly soft, touchable fabric. A flatter waistband and close fit can stop the rolling and rubbing that irritates the hip and waist during movement.
• Casanova Thong - Cherry: Sheer fabric extends from pouch to hip and over the back to form a seamless G-string, with a solid fabric lined pouch. A seamless construction removes raised stitching in high-friction zones, which is useful if seams are your main trigger.
• M.V.P. Retro Cropped Tee - Forest: Crafted in a luxe cotton-blend rib that hugs in all the right places. If chafing happens under a top or strap, a smooth cotton-blend rib layer can reduce rubbing against the skin without adding bulk.

Chafing is a signal, not a sentence. Identify where it happens, match the cut and fabric to that spot, and stop testing anything over broken skin. When a pair stays put and dries fast, you stop thinking about your underwear — which is exactly the point.
