Best underwear I have worn

Best underwear I have worn, hands down

Great Underwear

Love these. My wife got them for me and I've been really enjoying them. Hoping these bring some success! She read it was key to wear them every day so the 6 pack is great

Most comfortable underwear I've ever worn

I purchased these based on my wife's insistence but WOW I did not expect to love these as much as I do. Right now I'm wearing these every day to hopefully up my sperm count but even after we conceive (fingers crossed!) I don't see any reason to go back to my old boxer briefs. These feel like going commando in the best way possible. I always loved taking my briefs off at the end of the day and throwing pajama shorts on but now I feel like I can still have that comfortable and free feeling without dealing with bunched up boxer short legs in my pants.

"I'm so happy I found this company. I didn't realize how much control I had over my fertility levels. I only wear boxer briefs and hate traditional boxers so these were perfect for me. Tight in the right spots and loose in the right spots."

"These are extremely comfortable. The starter kit is great and the order came with a great info card that tells you exactly what you need to go to increase your sperm count. Looking forward to taking my next sperm test to see how much I improved."
