Kevlar reinforced underwear

A UK firm is manufacturing boxers reinforced with double layers of Kevlar. Blast Boxers “helps prevents blast and fragment injuries to the groin”.

They cost around $110. I would do some research before purchasing them. Kevlar is not magic and I am not sure how much flying debris will be stopped by two layers of knitted kevlar.

[ Many thanks to Mik for emailing me the info. ]

    That’s the firm trying to save the royal jewels of the UK soldiers. 🙂


    • Pd, thanks. I forgot the link.

    I want to see them tested, so so badly.

    I will buy 100 pair if they supply video of some dude taking an RPG-7 to the balls.

    When the groin area is at stake every little bit of protection helps.

    What’s next? A ceramic strike-cup?

  • I have a buddy deploying in a couple months, perfect gift!

  • Madeleine Goddard

    I can think of three good reasons why I’d buy a pair for my boyfriend in the Marines.

    Add a flame retardant layer and you’re good for anything the internets can throw at you!

  • How many layers are in a vest and required to stop a bullet?

  • Matt

    A class three vest takes 30-someodd layers to stop standard hand gun rounds. I really dont see these doing more than stopping potential scratches from the lightest of fragmentation, and making one feel better about ones….ahem…. testicular safety.

    And of course being an awesome gift for a soldier. Which makes them ok in my book. As long as they don’t cost too much.

    Kevlar weakens when exposed to moisture, but I guess it’s better than your poly/cotton pants. If I was serious though I’d go for Crye’s LAP panel or something similar. Proper groin armor is not that unusual.

    Incorporating into underpants (which need to be washed regularly necessitating multiple pairs) does sound new. Without tests I doubt that is stopping any shrapnel.

    Think thats the stuff the MoD where looking into for soldiers in afghanistan. They were on about protecting the groin while in a vehicle. Cant help but think it would be better to put a steel plate under your seat

    the website says they will protect up to 230mps (754fps) in the standard NIJ V50 test. That’s a pretty weak projectile — pretty much fragments only. Also, it only covers the crotch and inner thigh, the outer thighs are unprotected by this.

    If you worry about bomb fragments, it may be worthwhile; but as people have pointed out there may be better solutions.

  • Ha! An RPG-7 to the balls. If they did that, they’d sell out in seconds. That would go viral.

    Vest takes a lot of layers to stop a bullet per the NIJ standards, but I saw someone shoot an old one 3A with an MP5 a few weeks ago and the bullet was stuck in between the first and second layer. It was a suppressed subsonic round, but that apparently is where bullets it can handle stop. (I’ve heard suggestions that the backface deformation stuff is why you need the extra layers.)

    Well, lets just hope the unlucky wearer doesn’t get too scared in any blast then! 🙂

    Guhhh, NOT the perfect gift for any soldier. I’ll pass on walking around with a bucket of sweat strapped to my groin.

  • Seamus

    i decided long ago that i would rather take a bullet to any other part of my body, kill shot or not, than to my beloved junk. when i am deployed, this will be a necessity. you may call me a fool for my preference of death over the destruction of my penis, but i do not care. thank you kevlar. thank you.

    I see a few issues here, these are the drawbacks to this…

    1. Potential heat casualties. I’m an Infantryman, and Kevlar is a familiar friend of mine… But it retains body heat and becomes an oven that is a few degrees above hell.

    2. Sweat. You will sweat like crazy in those undies. That will cause the Kevlar to break down and become useless. Not to mention the need to wash them constantly, and the $110 price tag per pair.

    3. Ballistic Rating. This stuff is weak. The average air rifle or slingshot fires their projectiles faster than 750fps. If it won’t stop a BB, it’s useless to me.

    4. Sanitation. Has anyone noticed that over time, your vest starts to smell like year old gym socks? That is bacteria thriving in the crannies in your vest. Just imagine the skin infections that will have to be treated after wearing those knickers for a few days, and could take a rifleman out of the fight.

    5. False sense of security. A young soldier that really doesn’t know his head from his buttocks will think he’s better protected than he really is. He will pay less attention for IED’s and land mines. A shot in the femoral artery can kill you in less than 30 seconds if left untreated.

    The only plus that I see, is that you won’t scratch as badly when you fall down the mountain on you arse.

    Well I just had a brilliant idea, a kevlar waist apron. something light enough to stop shrapnel not a bullet, that should give the sensitive veins and arteries in the groin area more protection.
