    Knixteen Boyshorts

    I ordered five pairs for my daughter and they have become her "go to" panties. I bought them in anticipation of her period and she is already feeling comfortable in them.

    Good quality

    I tried the Knixteen line after finding the women's sizing to be a touch too large for my frame.

    Ordered a size L in these and they fit much better. I prefer the overall style of the bikini-type bottoms better but in terms of fit, these are far superior. I actually find that these boyshorts fit snugly and don't move around, which is exactly what one wants with period underwear!

    For reference I'm 5'3 and about 125 pounds. If you have a small frame, go for either a size Large or even a Medium in the Knixteen line if you find the regular sizes a touch too large!

    Best ever.

    I’m a 61 year old woman. After reading the reviews I decided to try these. My usual size is small or size 4. I ordered the size large & they are a perfect fit. They don’t ride up, dig in, give a vpl, are comfortable & becoming. Also great for a weak bladder & sneezes etc.
