Nice products and customer service... slow shipping

Hi! I am a teen girl who has been wanting period undies for a while, after debating about it for a long time, my mom and I ordered the period kit and one pair of extra undies (with the discount code we used it came to be the same price as just the kit!) The shipping took over 3 weeks to come from Toronto to Halifax where we live but luckily the day they undies arrived I started my period (lol) For reference I am 5'4", 120 pounds and have 36" hips. From these measurements I ordered a size large. The underwear fit good but if they stretched they would be too big and the shorts were huge. I contacted the company and they said that the products should fit SNUG AT FIRST AND RELAX WITH WEAR so keep that in mind when you purchase. The Knixpert I spoke with was extremely kind and gave me a full refund so I could rebuy the kit in a size medium instead. I did, and they just came today and are a much better fit!

The underwear is super comfy and does not show underneath leggings! The material is comparable to swimsuit bottoms and the fit is awesome. I ordered the boyshort style to have that little bit more coverage and am in love. I wore these on my period and they stopped any leaking. I was able to wear them alone on my lighter days and instead of a liner on heavier days. The only thing that was weird is that only my first package came with the Knixteen swag. I would have liked to see the second set we got have it as well but I'm happy with what I have :)

Overall, even though these…

The best first period kit!

I bought this for my 11 year old who is about to get her period. She was so excited and feels comfortable and confident for her first period.

In Love!

My daughter loves her period kit! It's her first time using "period underwear" and these ones are so comfortable and keeps her feeling dry. She loves the shorts too and has been wearing them around the house non-stop while we're quarantined. Such a great way to try out the brand and get some cute swag too.

Period kit for 11 year old

My daughter loves the Boyshort Underwear, this helps so much with the fear and anxiety around daytime leaks and makes her heavy period a little less terrible. The sleep shorts are saving us having to deal with stained sheets every morning as well. Love this product! Wish these were available when I was a teen.
