An Open Letter from the Owner of Bohn: Yes, Your Body Armor Expires. Here is Why.
Lately, I have been fielding a lot of emails and phone calls from rather "frustrated" customers. Customers are calling us bent out of shape because the armor they bought from us prior to 2020 has started to crumble, crack, or fall apart.
The Science Doesn't Care About Your Feelings
Modern, premium gear utilizes high-tech viscoelastic polymers. This is the incredible, cutting-edge material that stays soft and flexible while you ride, but instantly locks up to absorb energy the second you hit the asphalt.
But to give you that level of comfort and advanced protection, that material relies on a complex chemical structure. The moment you start wearing it, it begins fighting the elements:
- The Chemical Reality: Ambient heat, body sweat, humidity, and UV rays slowly cause molecular oxidation. Protective materials inherently degrade over time just from existing—even if you’ve never had a single crash.
- The "Squish Test": As we officially outline in our own Bohn Body Armor Care Guide, your armor should always feel firm but pliable. If you pull out your old pads and they feel rock-hard, brittle, or slow to snap back, the chemistry has failed.
- The 40% Protection Loss: Laboratory stress-testing on used motorcycle gear shows that after 4 to 5 years of regular exposure to the elements, armor can lose up to 40% of its impact absorption capacity. If you crash on 8-year-old armor, it’s not going to absorb the blow as well as it would have when you bought it. Your bones will.
Technology Moves Forward—And So Should You
Think about it this way: technology changes fast. You wouldn't expect a cell phone from 2020 to run like a brand-new model today, so why would you treat life-saving limb and spinal protection any differently? The reality is that the armor built in 2020 or earlier was using vastly inferior tech compared to what we are engineering right now. Back then, most standard gear on the market was only rated at CE-Level 1. Level 1 armor is better than nothing, but it still allows a massive amount of impact force to transfer directly into your body.
To understand why today’s gear is so much better, you have to look at the actual physics—measured in kilonewtons (kN) of transmitted force. Lower numbers mean less force hitting your body.
For your limbs—shoulders, elbows, hips, and knees—old CE-Level 1 armor allowed up to 35 kN of force to smash into your joints. Our upgraded CE-Level 2 limb armor reduces that to 20 kN or less. When it comes to your spine, the stakes are even higher: a Level 1 back protector passes up to 18 kN straight to your vertebrae, while a CE-Level 2 back protector caps that dangerous force at just 9 kN—literally cutting the impact energy in half.
Even better, some of our newest premium viscoelastic armor inserts are testing at an incredible 20% to 40% higher than those strict industry minimums. The newer armor is softer, lighter, much better ventilated, and astronomically safer. Riding on older, expired technology isn't just outdated—it means you are actively leaving massive, bone-saving upgrades on the table.
We Made It Easy for You (So Stop Gambling with Your Limbs)
When your armor expires, we don’t make you buy the fabric shirt or pants all over again. The high-quality fabric portion of your Bohn gear is built to endure. All you have to do is pull the old, expired armor pads out of the pockets and slip a fresh set in.
A complete, state-of-the-art replacement armor kit costs right around $100.
