Arbortec ATHV4060 Breatheflex Pro Chainsaw Trousers - Design A Class 1 Hi-Vis Orange
The Arbortec ATHV4060 Breatheflex Pro Chainsaw Trousers - Hi-Vis Orange are engineered for arborists who require exceptional visibility, mobility and breathable front-leg chainsaw protection. Constructed with high-tenacity polymer fabrics and Kevlar reinforcement, these trousers combine lightweight performance with outstanding durability for demanding daily tree work, certified to EN 381-5 Class 1 (20 m/s) Design A.
Sized XS to 3XL across Short, Regular, Long and Extra Long leg lengths, they're in stock at Gustharts as an authorised Arbortec dealer, with free UK delivery on this order.
The abrasion-resistant Kevlar panels on the front and ankle areas provide superior protection against scuffs, impacts and friction from bark and branches. A Kevlar-reinforced stretch crotch increases tear resistance and enhances freedom of movement — making them ideal for climbing and canopy work.
Every pair of ATHV4060 trousers is hand-crafted in Arbortec's Portuguese manufacturing facility, ensuring exceptional build quality and the ability to refine the design quickly based on real arborist feedback.

Technical Details
Why Choose the ATHV4060 Hi-Vis Type A?
Arbortec has built its reputation specifically around arborist workwear developed with climbing professionals, and every ATHV4060 pair is hand-crafted at their Portuguese facility rather than mass-produced overseas — that closer manufacturing link is why the range gets refined quickly based on real arborist feedback. Choose this Hi-Vis Type A if you need certified visibility with front-leg protection and rear ventilation; choose the Hi-Vis Type C instead if you need full front-and-rear coverage in the same visibility class.

Certified Protection Explained
EN 381-5 Class 1 (20 m/s) Design A means these trousers have passed standardised chainsaw contact testing at 20 metres per second, with cut protection covering the front of the leg only. EN 381-5 is gradually being superseded by EN ISO 11393, the newer international equivalent — current Arbortec stock is certified and labelled to EN 381-5, which remains valid and widely accepted across UK forestry sites.
