Pros
- EN381-5 Class 1 certified — genuine cut protection, not just workwear
- Lighter and cooler than Class 2/3 trousers, easier to wear all day

- Front-only protection — no cut resistance at the back of the legs
- Sizing runs by waist/leg combination, so check the chart before ordering
What it does
Chainsaw trousers work on a simple principle: the outer shell is cut through instantly, but the layers underneath contain long, loose fibres that jam a moving chain almost immediately, before it can reach your leg. These are certified to EN 381-5, Class 1, which means they’ve been tested to stop a chain running at 20 m/s — the entry-level speed band, and the one that covers most garden and smallholding machines rather than high-output professional saws. They’re Type A, so the cut-resistant padding runs down the front of both legs only, which is where the overwhelming majority of real-world leg injuries happen when a blade or chain kicks back or a foot slips.
For brushcutter and clearing-saw work specifically, this matters even without a chainsaw attached: a metal brush blade spinning at speed behaves similarly to a chain if it makes contact, and these trousers give a genuine layer of protection that ordinary work trousers or overalls don’t.
Choosing and fitting
There’s no exact fitment chart to match against a machine here — chainsaw trousers are sized like normal workwear, by waist and inside-leg measurement, with most ranges offering a regular and a short leg option. The elasticated waist and adjustable belt loops or braces give some tolerance, but it’s worth measuring before ordering rather than guessing, since a pair that’s too long will bunch at the ankle and catch, and one that’s too tight will restrict movement and encourage you to leave them in the shed.
Class 1 is the right choice for most brushcutter owners, occasional chainsaw users, and anyone running a lower-powered saw or trimmer — they’re noticeably lighter, cooler and less bulky than Class 2 or Class 3 trousers, which makes them realistic to actually wear on a warm day rather than something left in the garage. If you run a high-output professional chainsaw regularly, or work at higher chain speeds, step up to Class 2 for the extra margin.
Honest limitations
Class 1 protection is a floor, not a ceiling — it’s tested at 20 m/s, and a faster-running saw can exceed what the fabric is rated to stop. The front-only protection area also means these do nothing if a blade contacts the back or side of the leg, so proper technique and stance still matter as much as the trousers themselves. Like all chainsaw-protective clothing, the fibres are a one-use safety feature: a pair that’s been cut into has done its job and should be replaced, not patched up and trusted again.
