Customer Reviews
Solid value, minor issue
I bought a couple pairs of the Leakproof Bikini underwear, and overall, I'm happy with them. The leakproof tech works as advertised, which is the main thing. They're comfortable enough for everyday wear, and the sizing guide on the website was accurate. Shipping took about a week to get to me in Oregon, which is okay, but not super fast. I wish the waistband felt a little more substantial; it feels a bit thin compared to some other brands I've tried. Still, for the price and performance, it's a good purchase.
Good deal on first order
I was looking for some new activewear and saw Knix had a 15% off first order deal, which was great. I got the HiTouch High Rise Legging and a matching Tank Top. The price felt fair with the discount, definitely helped me decide to try them out. Shipping was free because my order was over $75, which is always a plus for me. Everything arrived in about 5 days, which was faster than I expected. The leggings fit well and feel good quality, so I think it was worth it for the price I paid.
Good bra, quick shipping
Got the Catalyst Sports Bra. Fit well. Shipped fast, got it in 4 days. Would buy again.
Consistent quality, reliable brand
This was my fourth order from Knix, and once again, they delivered. I picked up some more of the Longevity Bras and a few pairs of the Super Leakproof Underwear this time. I've been getting their products for a couple of years now, ever since I first tried their Evolution Bra, and the quality has always been consistent. The bras hold up well after many washes, and the leakproof undies are a lifesaver. My last order took 6 days to get to Phoenix, same as this one, so shipping is pretty reliable too. Always happy to come back to them.
Knix Community Discussion
Share tips, ask questions & help fellow shoppers save more
Hey, I'm thinking about getting some of their leakproof undies. How accurate is the sizing usually? Don't want to get stuck with something too small or big.
Does Knix have a student discount? My friend mentioned something about it.
Are Knix bras actually good for larger busts? I've tried so many wireless bras that just don't offer enough support.
Thinking of buying some of their period underwear. Are they actually PFAS free? Seen some other brands get called out for that.
What's the return policy like for the underwear? Can you return it if it's just not working out, even if you tried it on?
