The Arbortec Breatheflex Type C Chainsaw Trousers provide full-wrap chainsaw protection with a lightweight, flexible build designed for arborists, foresters and, in the hi-vis version, rail-side professionals. This model covers Class 1, Class 2 and Class 3 versions.
Design C protects the front and back of the leg. The protection classes are 1 (20 m/s), 2 (24 m/s) and 3 (28 m/s): higher classes are rated against a faster chain, so choose the class your risk assessment and employer require. Six-way stretch fabric and a breathable outer keep them workable for long days.

AT4050 Chainsaw Protection
All versions are Design C, with protection to the front and rear of the legs. Pick the protection class from the options on this page: Class 1 (20 m/s), Class 2 (24 m/s) or Class 3 (28 m/s).
Comfort & Durability
Six-way stretch fabric gives unrestricted movement in the tree, and the Climasphere outer is breathable and abrasion-resistant. Kevlar® reinforcement at the crotch and lower leg, reinforced seams and ankle lining all target the high-wear areas.
Care note: do not tumble dry. Always air dry.
Pockets & Harness Use
The pocket zips face downward, which makes them compatible with a climbing harness, and the cargo and phone pockets have protective fold-over flaps.
Size Guide
Choose your waist size and leg length carefully, as chainsaw trousers should fit correctly to protect you properly. Our Arbortec size guides page has the measurements to check against.
