I've purchased over a dozen pairs of Knix underwear since 2016, a combo of the essential bikinis and leakproof. They are comfortable and great for active people as they dry fast. Excellent for workouts, hikes, etc. They help neutralize when things get funky/sweaty, if you know what I mean. BUT...and this is a big but for me – I just had 5 pairs start to fall apart after being put in the dryer. I know, I know I should follow the care instructions that say lay flat to dry. But sometimes your boyfriend does the laundry and he doesn't remember to take out the lingerie bag and it ends up in the dryer, you know?!
It's a bummer to spend $18/pair on underwear that can't stand up to a medium heat run through the dryer. Every dried pair has the same issue of the crotch seam peeling apart from the gusset, and I have to assume it will keep peeling away over time. So – take my sad tale as a cautionary one. DO NOT DRY YOUR KNIX UNDERWEAR. It's crazy to me that others haven't had this issue. Maybe I'm just irresponsible with my laundry.
