OVERVIEW

Weld in Comfort All Day Long

If you use an Adflo PAPR system, you know that carrying the blower unit on your waist for an eight, ten, or twelve-hour shift can take a toll on your lower back. The 3M Speedglas Heavy Duty Back Pack (BPK-HD) is the solution you've been looking for. Designed to replace or supplement the standard belt, this backpack harness lifts the weight off your hips and spreads it evenly across your shoulders and back. It feels much lighter and allows you to move more freely, especially when you are bending, crouching, or welding in out-of-position scenarios.

This isn't just a generic backpack; it is custom-built for your Speedglas gear. The "Heavy Duty" designation means it is tough enough to handle the sparks and grime of a real shop environment. The straps are easy to adjust, so you can get a snug fit over your welding jacket without it slipping around. Whether you are doing production MIG or precision TIG work, staying comfortable means you can stay focused on the puddle, not on your back pain. Upgrade your setup with the BPK-HD and feel the difference at the end of your shift.

Why Welders Love It:

  • Save Your Back: No more heavy battery pack dragging down your pants or digging into your waist.
  • Stay Mobile: The backpack profile keeps the unit tucked away, reducing the chance of snagging on equipment.
  • Built Tough: Made to last in the shop, just like your Speedglas helmet.
