Why It's Built Different
Six Layers + Backpad
Six layers of Kevlar cover the full front, plus 4″ up the left, from 4″ above the crotch to the ankle, plus a 360° Kevlar backpad from knee to ankle.
Front and Back Built Different
A 600-denier woven polyester front resists abrasion; the knit polyester back breathes.
Made for Slashing Crews
Belt loops where you need them and a heavy-duty nylon seat patch for the abuse the job hands out.
Kevlar where it counts
Most chainsaw pants protect the front of your thigh, down to the ankle, and that's it. Ours cover the full front of each leg, 180°, plus 4″ up the left side of each leg, from above the crotch to the ankle, right over the femoral artery where a kickback is deadliest. The Seismic ProMax adds a full 360° backpad.
SEISMIC PROMAX 180° + 4″ left above the knee · 360° below
180° of front wrap plus 4″ up the left (bar) side above the knee. From the knee down, the backpad closes the circle: a full 360°. The dot marks the femoral artery: inside the coverage.
Typical competitor front pads only
Front-of-thigh pads, usually starting below the crotch (dashed zone): the artery zone, the sides and the whole back stay exposed.
Loose inserts under jeans pads shift
Kevlar pads tucked under jeans move while you work: no fixed coverage where you need it.
