Like the right running shoes or perfect leggings, underwear can make or break your workout. Just try to get a personal record while pulling a wedgie out of your butt every 30 seconds! When working out, you need underwear that’s up for the physical challenge. Here are 3 factors to consider.

1. Sweat

Breaking a sweat? Good. Sweaty underwear? Bad. A swampy butt would make anyone cut a gym session short. To avoid that, make sure you have moisture-wicking underwear. Start by trying silk panties. 

While you might not think of silk as an athletic material, it actually is the best material for sweat wicking underwear. When silk gets wet, it locks moisture inside the material so you cannot feel it. That’s because silk can hold 30% of its weight in moisture before feeling wet to the touch. It’s kind of magical! Silk fibers are also among the most durable, so you can wash them relentlessly and keep them for many sweat sessions to come. For breathability, also look for underwear with a 100% cotton gusset (that’s the extra material sewn in at the crotch).

2. Wedgies

The cut, fabric, and size of your panties can all influence its wedgie-factor. While working out, you want underwear that won’t over stretch. It should also be cut around the entirety of the buttocks so it lays flatter and smoother on your body. If it is cut across the buttocks, it will creep inwards causing wedgies if you start to move a ton while exercising. At Uwila Warrior, we cut all our undies with this in mind.  

Here’s another tip: avoid anything that is too small. In other words: size up for your workout panties. Thanks to our Perfect Fit Promise, if you don’t like the fit of your first pair, we’ll send you a different size or style of a similar price point, free of charge.

3. Panty Lines

You might prefer doing your squats or downward dogs without showing off visible panty lines. Thankfully, you have options. Seamless underwear comes in many shapes and forms, including briefs and thongs. 

Both Uwila’s VIP Thong and Happy Seams briefs have laser cut edges at the waistband and leg openings to ensure they’re panty-line free. These details give a smooth appearance under clothing, and also help you avoid painful rubbing when working out. Pain is not gain when it comes to your undies..
