Arbortec ATHV4070 Breatheflex Pro Chainsaw Trousers - Design C Class 1 Hi-Vis Orange
The Arbortec ATHV4070 Breatheflex Pro Chainsaw Trousers - Hi-Vis Orange are engineered for professional arborists who require maximum visibility, all-round leg protection and exceptional mobility. High-tenacity polymer fabric delivers outstanding strength while remaining lightweight enough for climbing and intensive aerial work, certified to EN 381-5 Class 1 (20 m/s) Design C and Hi-Vis compliant to EN ISO 20471 RIS-3279-TOM.
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.
Abrasion-resistant reflective panels on the knees and ankles withstand daily wear against bark, branches and equipment while enhancing low-light visibility. A Kevlar-reinforced crotch prevents ripping and offers stretch for climbing, and a redesigned comfort liner eliminates sawdust trapping.

Technical Details
Why Choose the Breatheflex Pro Hi-Vis Type C?
Arbortec has built its reputation specifically around arborist workwear developed with climbing professionals, and this Hi-Vis Orange Design C model exists for roadside, rail and utility arb teams who need certified high visibility alongside full-circumference chainsaw protection — not every Type C trouser meets EN ISO 20471. Choose this over the standard (non Hi-Vis) Breatheflex Pro C if your site rules require certified high-visibility PPE; choose the Breatheflex Pro Type A instead if you don't need rear-leg coverage and want lighter, more ventilated trousers.
Compare Hi-Vis Type C vs Standard Type C vs Type A
| Model | Protection | Hi-Vis Certified | Best For |
| ATHV4070 Hi-Vis C (this model) | Type C, front and rear leg | Yes — EN ISO 20471 | Roadside, rail and utility work requiring certified hi-vis |
| Breatheflex Pro C (standard) | Type C, front and rear leg | No | Full-circumference protection, no hi-vis requirement |
| Breatheflex Pro A | Type A, front leg only | No | Warm-weather climbing, maximum mobility |
Certified Protection Explained
EN 381-5 Class 1 (20 m/s) Design C means these trousers have passed standardised chainsaw contact testing at 20 metres per second, with cut protection covering the full leg circumference. EN 381-5 is gradually being superseded by EN ISO 11393, the newer international equivalent — current Arbortec stock is certified and labelled to EN 381-5, which remains valid and widely accepted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. EN ISO 20471 RIS-3279-TOM is the high-visibility clothing standard used across UK rail and roadside work — RIS-3279-TOM is the Rail Industry Standard specifically for trackside PPE, so this garment is suitable where rail-specific hi-vis compliance is required.

Complete your kit with a certified chainsaw helmet, a pair of chainsaw boots, and chainsaw gloves to bring your protection up to a matched standard.
