D3O in the Cirro Suspenders: Advanced Impact Protection for Tradespeople

When you carry tools all day, your shoulders take a beating. Over time, that strain adds up — and can lead to pain, injury, or even early retirement from the trades. That’s why the Cirro Suspenders from Diamondback are engineered with D3O® impact protection, providing unmatched shoulder support that adapts as you work.

What Is D3O?

D3O is a patented, non-Newtonian material that remains soft and flexible under normal conditions but instantly stiffens to absorb and disperse energy when impacted. Originally developed for military armor and extreme sports, D3O is now trusted in high-performance safety equipment worldwide. Its molecular structure allows the material to flow freely in its resting state, then lock together on impact — making it both flexible and exceptionally protective.

How It Works in Cirro Suspenders

We’ve placed D3O padding directly in the contact points of the Cirro Suspenders to:

• Distribute the load more evenly across your shoulders

• Absorb shock from sudden movements, drops, or slips

• Minimize joint and nerve strain over long days

The result? You feel less fatigue at the end of your shift, with the freedom to move naturally and confidently. Over time, this reduction in stress on the shoulder joints can help prevent chronic injuries and support a longer, healthier career in the trades.

Designed for the Real Demands of the Jobsite

Unlike traditional foam or webbing, D3O protection is:

• Lightweight and low-profile

• Durable under pressure and over time

• Comfortable enough for all-day wear

• Tested to meet rigorous industrial safety standards

Whether you’re climbing, lifting, or reaching, Cirro Suspenders equipped with D3O help safeguard the areas that take the most punishment. This is protection you won’t feel — until you need it.

Protect your tools, yes — but protect yourself first.
