Spoiler alert: zero leakage.
I've always been intrigued by the idea of Thinx, but I'd never felt like I *really* needed to try them—until I heard they were coming out with activewear, that is. For those who haven't heard, Thinx introduced a line of underwear a few years ago that makes pads, tampons, and menstrual cups totally unnecessary when you're on your period. Though I don't mind wearing a tampon in general, the idea of not having to wear one while working out is pretty appealing, especially since tampons are known to leak during exercises like squats. (Eek!) So when I had a chance to test out the training shorts ($65; shethinx.com) the brand just introduced, it was a no-brainer. (BTW, there are some benefits to exercising during your period.)
When my period-proof shorts arrived in the mail, I noticed that they didn't really look like anything special, but I guess that's the point. There's basically no way to tell the difference between these black running shorts and any other pair, which means you can wear them without anyone knowing that you're casually bleeding into your activewear. (Not that you should care if anyone knows. ICYMI, people are obsessed with periods right now. But it's nice that the option to be discreet is there for those who want it!)
Once I put the shorts on, I realized that they're pretty short. I'm not tall nor do I have particularly long legs, so I wouldn't recommend these unless you're comfy wearing short-shorts. My first impression was that these would be great for running, but not so great for exercises like squats (would they ride up?). There's a built-in brief, just like any other pair of running shorts, and while I expected the liner area to be kind of thick and weird, I was pleasantly surprised to find that it wasn't much bulkier than a regular pair of underwear. I didn't feel it at all during my workout.
So what was it like to work out in them? Well, even though my period is blessedly light (thank you, birth control), I still had an overwhelming fear that I would leak period blood EVERYWHERE while testing these. What would happen during all those squats I was supposed to do? Or what about when I lay down on my gym's light gray (eek!) yoga mats to do hip bridges? Spoiler alert: There was no leakage. The shorts held up through my bike ride to the gym and even a few rounds of burpees. As I progressed through my sets, I stopped checking to make sure I wasn't leaking all over the place.
While everyone's period is different, I'd say most people should feel secure wearing these with no additional protection on a light or medium flow day. And even if you're not into the idea of working out without a tampon or something similar, it's nice to know that these shorts offer an extra layer of security. After all, there's nothing worse than accidentally bleeding onto your favorite leggings that you fully splurged on—or being distracted from your workout by the persistent worry that you might.
My only teeny-tiny complaint? Ultimately, it comes down to personal preference, but I hope Thinx expands their activewear collection to include a legging option. I probably won't wear these shorts that often because I just don't find shorts comfortable. To be blunt, my thighs and shorts don't get along, no matter how hard I work out. On the other hand, if you'd prefer to work out in shorts, you're in luck, because these are pretty comfortable as far as shorts go. Overall, if you're totally happy with your period workout situation, there's probably no need to switch it up. But if you're looking for a second layer of defense from leaks or if you'd rather skip feminine products during exercise, get yourself a pair of these ASAP.
