The Best Seamless Underwear for Runners

Looking to improve your running performance? The key might be a good pair of panties.

Wearing comfortable running underwear that stays in place and keeps you dry can make all the difference. And if you opt for a seamless pair, you don’t have to worry about underwear lines showing through your workout clothes either. Below we’ve outlined all the underwear details that will keep your run on track. Ready. Set. Go!

Comfortable Running Underwear: What to Look For

The best kind of running underwear is the kind you don’t even notice. But while you’re focusing on your fitness, we’ve given attention to all the underwear details. From the material to the finish, our Happy Seams seamless briefs have key qualities that make them a great option for runners. These include:

• Lightweight and non-chafing materials
• No panty lines under leggings and shorts
• Seams on the size
• Tags that rip out
• Cotton gusset (otherwise known as the crotch area)
• Sweat wicking fabric

These seamless panties will also sit into you running leggings so they don’t move around or bunch up. With that barely-there feeling, you can focus on getting that personal record.  

Choose Moisture Wicking Underwear 

Another key to comfort: staying dry. Excess moisture from working can breed bacteria and cause yeast infections. In all of our underwear, we use either natural moisture-wicking materials or an ultra lightweight — and very breathable — nylon blend.  

When to Consider a Thong 

 There are times runners might consider a thong vs. a seamless brief. If you’re looking for something just a little bit lighter while working out, or are a dedicated thong wearer, look for a thong with a cotton gusset for maximum hygiene and removable tags. In our thong we’ve considered both of those details, and have also eliminated the back gusset seam, so there is nothing to dig in back there and cause discomfort.
