Sleep boxers
Gave me leakproof security throughout the night and are super comfortable in every way. I will be saving up to buy more.

I live in these
I have bought a pair for everyday of the week. I run around in my house with these boxer shorts and a light shirt. I forget sometimes that I need shorts to leave the house. They are coo, super soft and comfy.

The best!
These luxe modal boxers are my favorite. For my shape (curvy) and type of work (actively moving the entire time/sitting, standing and walking), they are the softest and most comfortable material for all day or all night wear - good for all day at work without feeling bulky or restrictive; and great for nights, easy and supportive (wicks sweat and leaks with or without periods). These are better than the dream short because the material is lighter in these with a secured and smooth leg area and the waistband fits nicely but not tight, whereas the dream shorts sort of slide down from the waist over time and throughout the day and their fit is more of a brief which isn't right for me.
Knix please keep making the Lue Modal Leakproof Sleep Boxer product - there was a time when production stopped and there's not another product like this. Also, please make these in more colors, can we do more than black and mushroom? : ) thank you for considering this!
