STIHL Advance FlexTEC Trousers -Design C, Class 1

Trusted Safety for Professional Work

The STIHL ADVANCE FlexTEC trousers offer full-leg protection for forestry, landscaping, and arborist professionals using chainsaws regularly. These trousers are certified to Cut Protection Class 1, Design C, giving complete front and rear leg coverage when operating chainsaws. The protection meets EN ISO 11393 and EN 381 standards, offering reliable safety where consistent performance is essential in daily use. While no clothing can guarantee complete protection, these trousers offer peace of mind through their professional-grade construction and tested design.

Lightweight Cut Protection Without the Bulk

The 6-layer AVERTIC™ Pro lite+ material delivers outstanding protection while staying light and breathable during physically intense tasks. Compared to standard 9-layer protection, this lighter option offers equal safety with reduced weight and improved working comfort. These fibres are designed to resist cutting, absorb moisture, and allow quick drying in cold, wet, or variable outdoor environments. This design keeps the user focused on their work without being restricted by uncomfortable or heavy layers during long hours outdoors.

Maximum Flexibility with Full Stretch Design

Full-stretch fabric makes these trousers highly flexible, adapting to movement while providing continuous protection from waist to cuff. This elasticity means you can crouch, climb, or stretch without the fabric pulling or restricting you throughout the day. The crotch and leg areas feature a ProElast stretch insert which allows extra mobility in awkward or demanding working positions. This insert is not sewn traditionally, but joined elastically, allowing consistent protection even when legs are positioned at sharp angles.

Breathable Material with Adjustable Ventilation

Built-in thigh zippers let you control air flow depending on temperature, letting you stay comfortable in changing conditions. During hot weather, simply open the vents to release heat and increase airflow where it’s needed most on your legs. The fast-drying inner fabric helps wick sweat away from the skin, preventing hypothermia in colder or damp working environments. This feature is ideal for jobs involving physical labour in shifting weather, especially when you’re working for long periods.

Tailored Fit with Smart Practical Features

An adjustable Velcro waist gives you a snug fit suited to both male and female wearers with varying body shapes. Elasticated cuffs around the calves keep out ticks, sawdust, and snow while also resisting abrasion and sharp thorns. The reinforced knees are waterproof and durable, giving added protection during kneeling tasks or jobs in wet undergrowth. You’ll also find several practical pockets, including side, thigh, ruler, and back pockets, all with protective flat zip closures. These zips are designed to prevent clogging from resin or debris, so they function reliably day after day. Buttons and loops allow braces to be attached securely, helping support the trousers during long shifts or climbing work.

Eco-Conscious and Durable Construction

The outer fabric is made from 89% polyester and 11% elastane, providing durability without compromising freedom of movement. The lining and cut-protection materials are made from 100% recycled polyester, supporting sustainable choices in your gear. A PFAS-free water-repellent finish offers added protection across the lower legs without harmful chemical treatments. The trousers are machine washable at 60°C, making maintenance easy after muddy or resin-covered workdays in the forest.
