Why Your Underwear Matters at the Gym
Let’s face it—gym workouts come with a fair share of sweat, movement, and friction. Choosing the wrong undergarments can lead to:
-
Chafing and irritation
-
Excess moisture and discomfort
-
Visible panty lines (VPL)
-
Embarrassing tugging or readjusting
According to fitness experts and gynecologists, moisture-wicking, breathable, and seamless underwear is the key to a smooth gym session. When your body is in motion, your clothes should move with you—not against you.
The Best Types of Underwear to Wear Under Gym Leggings
Choosing the right underwear doesn't just enhance comfort—it boosts your performance too. Here are the best options:
1. Seamless Panties
No lines, no bunching, no worries. Seamless panties are designed to blend invisibly under leggings. Perfect for tight-fitting gym wear.
2. Moisture-Wicking Briefs
Say goodbye to sweaty discomfort. These are crafted with synthetic fabrics that draw moisture away from the body, keeping you dry during high-intensity workouts.
3. Performance Thongs
If you prefer zero visibility, thongs are a go-to. Look for soft, elastic, and seamless thongs that won’t dig in or ride up.
4. Period-Proof or Leak-Proof Activewear
For days when you need a little extra protection, period underwear made for workouts offers peace of mind with no pads or liners needed.

What NOT to Wear Under Gym Leggings
Avoid these common mistakes:
-
Cotton underwear: Though breathable, cotton absorbs sweat and stays damp.
-
Lacy lingerie: Irritating, itchy, and visible under leggings.
-
Underwear with thick seams or tags: These can rub against your skin, causing discomfort and rashes.
Going commando?
That’s fine if your leggings have a built-in gusset and are made of antimicrobial fabric but for most, it’s better to wear performance underwear for hygiene and support.
Compression Shorts & Shapewear: Good or Bad Idea?
Wondering if you can wear shapewear or compression shorts under leggings? You can! In fact, they can:
-
Smooth your silhouette
-
Offer extra support for intense workouts
-
Prevent thigh chafing
Compression shorts are ideal for HIIT, running, and weightlifting, while shapewear works best for light cardio or yoga. Choose breathable materials to avoid overheating.
Match Your Underwear with Your Leggings
Getting the right combo is crucial. Here’s a quick guide:
| Leggings Style | Underwear Type |
|---|---|
| High-waisted | Full coverage panties |
| Thin/flexible fabric | Nude-tone seamless thong |
| Compression leggings | Moisture-wicking briefs |
| Sheer/light leggings | Nude seamless or compression |
Pro tip: Layer with a crop top, sports bra, or tank from our best workout clothes for women collection for a head-to-toe gym-ready look.
Extra Tips for Choosing the Right Gym Wear
Beyond underwear, your overall gym workout outfit matters too. Here’s what to keep in mind:
-
Fabric: Opt for quick-dry materials like nylon and polyester.
-
Fit: Look for supportive, stretchy fits that hug your shape.
-
Waistband: High-rise leggings give core support and won’t slip.
-
Gusset: A triangle-shaped crotch panel reduces seam stress and adds comfort.
