    Modal fabric is the best!

    I'm absolutely in love with these. I wear them day and night for my LBL. The modal fabric is by far the best for me as I don't find them hot. They are super soft and fit like a glove. (I was on the borderline for sizing so I sized down and they fit perfectly.) The protection is perfect for my LBL and they don't feel bulky. They feel like regular underwear in terms of gusset comfort. I only wish they were a couple inches shorter so I can wear them under my bermuda shorts in the summer. I'll continue to buy modal fabric. I now have 8 pairs! (I also love the cotton modal high rise underwear. I hope they bring them back as they are currently out of stock.)

    So comfortable

    I wasn’t sure about the insert and how it looked but you really can’t see it and dang, these are comfortable. Make them non-leakproof for the rest of the month and in a 3 pack please! I’d wear them every night!

    Finally! Thank you!

    I’ve been hoping Knix would create a leakproof sleeping bottom for some time now. I really don’t like having to wear underwear under pajamas and this sleeper boxer is a great product. I just got it yesterday, wore it last night, will wear it again tonight. It fits well and performs even better. I just wish it were a little longer. Please make this product available in capri and pant lengths. I will definitely purchase at least one more boxer but I would buy LOTS of them if they were available in other lengths. Thank you Knix!
