Finally found underwear that truly doesn't show under tight dresses and leggings. The fit is great and they're surprisingly durable after multiple washes.

I have very sensitive skin and these don't cause any irritation whatsoever. The fabric is soft and breathable. I've ordered three more pairs since my first purchase.

These underwear have completely transformed my daily comfort. The moisture-wicking fabric is incredible and they stay put all day without rolling or bunching. Worth every penny!

After trying dozens of brands, these are hands down the most comfortable I've ever owned. They don't dig in, create lines, or shift around during the day. The price is high but the comfort level justi... See more

After trying dozens of brands, these are hands down the most comfortable I've ever owned. They don't dig in, create lines, or shift around during the day. The price is high but the comfort level justifies it completely.
The quality is definitely there and they're super comfortable. I love that they don't show lines under my clothes. However, the price point is pretty steep compared to other brands. I'll probably only buy them on sale going forward.
Solid, comfortable underwear that holds up well to regular wear and washing. The fit is true to size and they maintain their shape nicely. Would recommend for daily wear.
Maybe I had too high expectations, but these feel pretty similar to other mid-range brands I've tried. They're comfortable but nothing special for the premium price point.
Had to return my first order and size up. Once I got the right size, they're comfortable enough, but the sizing chart isn't very accurate. The fabric feels nice but nothing revolutionary.
Some styles are amazing while others don't work for my body type. The boyshort style is perfect but the bikini cut rides up constantly. Quality is good overall but inconsistent across different styles.
The underwear itself is good quality and comfortable to wear. My only complaint is that shipping took forever and customer service was slow to respond when I had questions about my order.
These are my go-to for long flights and travel days. They stay comfortable for hours and the quick-dry fabric is perfect when you need to do laundry on the road. Highly recommend for frequent travelers.
As someone who works out daily, these have been a lifesaver. No chafing, great breathability, and they wash beautifully. The seamless design is exactly what I needed.
Knix offers an inclusive size range from XS to 4XL in most styles. They provide detailed sizing charts and fit guides to help customers find their perfect size.
Knix underwear is made with soft, breathable fabrics and is designed to be gentle on sensitive skin. However, if you have specific allergies or sensitivities, it's recommended to check the fabric composition before purchasing.
