The Toughest Pen Around

The X-701 is as tough as they come. With a patent pending pressurized barrel, ability to write in harsh weather conditions, and durable, stainless steel barrel, this will quickly become your go-to every day carry pen.

  • Durable, light weight, stainless steel barrel
  • Anti-reflective matte black finish
  • Patent Pending Pressurized barrel allowing the pen to write on challenging surfaces (extreme angles, upside down) and temperatures ranging from -30 degrees F to 250 degrees F
  • Convenient lanyard loop making it easily attachable to a belt loop, backpack, or climbing gear.
  • Military Grade Drop Tested
  • 5x more durable than everyday plastic pens
  • Refillable with K-refill


The X-701 features a patent pending pressurized barrel, allowing the pen to write upside down and at extreme levels. The X-701’s pressurized barrel is what makes this product unique. Using this refill in other standard pens will not have the same pressurized results. 

Due to the pressurized barrel mechanism, some ink blobbing may occur when the pen is left retracted for an extended period of time.

    This is my favorite pen to use! I am a very active and busy college student who is always on the go, traveling all over. The pressurized barrel mechanism is very unique, something I have never seen before. I took this pen with me while I was on a hike and it withstood quite extreme conditions such as rain and cold. It is a very tough pen and I love being able to attach it to my backpack and other gear. Not only does it work great is also looks really cool.
