Forest & Arb Knowledge Hub

At ForestAndArb.com, we understand that for professional arborists and tree surgeons in the UK, safety and performance are not a choice—they're a requirement. That's why we're incredibly excited to feature the latest innovation from STIHL, the new STIHL Advance FlexTEC Type C Chainsaw Trousers, which were officially launched in July 2025 as part of their next-generation PPE range.

This is more than just a new model; it's the natural evolution of professional-grade PPE. For years, the HiFlex and X-Flex trousers set the standard for professional chainsaw protection from STIHL, becoming a trusted choice for durability and comfort. The HiFlex especially was a very popular design that brought the industry forward from the old days of the green "duvet" style trousers that dominated for the previous decade. The new Advance FlexTEC line builds on this established legacy, integrating years of research and development to create the next generation of arborist trousers, designed to meet the demanding needs of those who work at height and on the ground.

What are Type C Chainsaw Trousers and Why are They Essential for Arborists?

For those new to the profession, or domestic users looking to step up their safety, understanding the different types of chainsaw trousers is crucial.

• Type A Chainsaw Trousers: These provide protection on the front of the leg only and are designed for ground-based forestry work. They are the most common choice for many professional users and landowners.

• Type C Chainsaw Trousers: This is where the STIHL Advance FlexTEC truly shines. Type C chainsaw trousers offer all-round protection, with cut-protection material on the front, sides, and back of the legs. The Health and Safety Executive (HSE) in the UK strongly recommends this level of all-round protection for aerial tree work and climbing, where the chainsaw can be in any position relative to your body.

The STIHL Advance FlexTEC Type C Trousers are specifically engineered for this demanding environment, providing maximum safety and peace of mind when working at height.

Key Features of the New Advance FlexTEC Trousers

So, what makes these new chainsaw trousers stand out from the crowd and why are they the new top choice for tree surgeons in the UK?

1. Next-Generation Cut Protection: At the core of the trousers is the new AVERTIC™ Pro lite+ cut-protection material. This six-layer material is exceptionally light and breathable, yet offers robust Class 1 protection against a chain speed of up to 20 m/s. It’s a remarkable balance of safety and comfort.

2. Unmatched Flexibility and Movement: The "FlexTEC" in the name isn't just a gimmick. The trousers are constructed from a multi-directional stretch fabric, with a flexible ProElast insert in the crotch area. This design allows for incredible freedom of movement, essential for climbing, bending, and manoeuvring in tight spaces. Compared to older models, you’ll immediately notice the difference in how the trousers move with you, not against you.

3. Superior Durability & Comfort: Working in arboriculture is tough on your kit. The Advance FlexTEC trousers feature reinforced, waterproof elastic fabric on the knees and lower legs to protect against thorns, abrasion, and moisture. The inner lining and cut-protection materials are made from 100% recycled polyester, a nod to sustainability without compromising on performance. Thigh ventilation zips allow you to regulate your temperature on warmer days, wicking away moisture and keeping you comfortable throughout a long day's work.

4. Smart, Professional Design: With a slim fit that reduces snagging, a high-visibility orange design, and reflective stripes, these trousers are both practical and professional. They also include a variety of pockets with flat, resin-resistant zips, a kidney protection layer, and loops for attaching braces.

The Perfect Partner for Your New Chainsaw

The release of this new PPE range perfectly complements STIHL's other recent innovations. Imagine pairing your new Advance FlexTEC Trousers with the power and precision of the recently launched STIHL MS 400.1 Chainsaw.
