Protos Forest vs Arborist: which kit matches the job

Updated: 21 October 2026

You have seen both names on the same red shell and you need one rule. Protos Forest vs Arborist is a split by height. If the chainsaw leaves the ground, buy the Arborist. If the saw stays down, the Forest is the kit UK dealers sell for that job. The Arborist can also work on the ground when your risk assessment accepts EN 12492. The Forest stays a ground helmet. The [Protos forestry helmet comparison](/hub/protective-clothing/protos-forestry-helmet) lists the amazon.co.uk titles. Peter F. wrote this on 19 October 2026 from HSE chainsaw and aerial PPE pages and UK dealer copy.

What each kit is sold with

The Forest is the ground kit: an integrated visor and muffs, usually the coarser G16, hearing protection, and EN 397, EN 352-3 and EN 1731. It does not include a climbing chin strap. Gustharts states it is for ground work. The Arborist is sold for chainsaw work at height, and the manufacturer describes it as usable on the ground. UK pages add a Maclip chin strap, a crash absorber, muffs, and usually the finer F39 visor, and they state EN 397 and EN 12492. EN 12492 is the mountaineering-style helmet the Health and Safety Executive names for climbing. A finer mesh is a visor choice. The mesh visor page explains F39 and G16. Name the model from the strap, the crash absorber and the marks.

On the ground and off the ground

On the ground, the Health and Safety Executive lists BS EN 397, BS EN 14052 or BS EN 12492. Off the ground, the chainsaw page and the aerial PPE page ask for BS EN 12492. That is why an Arborist can fell timber, and a Forest page that says ground work is the aerial rule written as a product description. Buy the Arborist when any chainsaw work leaves the ground. Check EN 12492 on the helmet you receive. Buy the Forest when the saw stays down. A ground-only Arborist is a valid helmet with hardware the week may never load. The best Protos helmet page turns that into a short pick.

Do not convert a Forest

Do not add a chin strap to a Forest and call it an Arborist. Gustharts states that the Forest cannot be fitted with a chin strap afterwards. A current UK dealer says that conversion is not available. A strap from another helmet, fitted at home, is a different assembly from the Maclip fitting and the crash absorber. If the work has moved into the tree, retire a Forest from that job and buy an Arborist. Keep an Arborist for later ground felling when the shell is in date and the risk assessment accepts EN 12492.

What the UK shelf shows

In October 2026 UK shelves sit at about £180–£190 for a Forest and about £190 excluding VAT up to about £276 for an Arborist. Stored headers near £50 sit outside that shelf. B00I52AP8W at £227.70 names a fine visor and prints no EN number. B07FX8Y5XX prints EN 12492 at a stored £59.99, so confirm the live offer. The buying guide holds the full check before you pay.

Common questions

What is the difference between Forest and Arborist?
The Forest is the ground kit, with muffs and a metal visor, typically to EN 397, EN 352-3 and EN 1731, and without a climbing chin strap. The Arborist adds a Maclip chin strap and a crash absorber, and UK shops state EN 12492 as well as EN 397. The strap and the height standard decide the purchase.
Can I use a Forest helmet in a tree?
Use the Forest for chainsaw work that stays on the ground. Off the ground, the Health and Safety Executive asks for BS EN 12492, which is the mark UK Arborist pages state. Gustharts describes the Forest as a ground helmet. A similar shell in a photograph does not move a Forest onto the aerial list. Buy the Arborist before the work leaves the ground.
Can I use an Arborist helmet on the ground?
Yes, when your risk assessment accepts EN 12492 for that ground work. The HSE chainsaw page allows BS EN 12492 on the ground and requires it off the ground. A climber who also fells can keep one Arborist. You still need the muffs to seal and the mesh and eye protection the chainsaw page lists. The Arborist does not retire those checks.
Does the Forest include a chin strap?
UK Forest pages sell the kit without a climbing chin strap. A United Kingdom review on one Forest URL said the helmet arrived with no chin strap, which matches that ground specification, and that listing’s details block is messy enough that you still read the live parts list. The Maclip strap belongs on the Arborist, with the crash absorber.
Can I buy a strap later and upgrade?
Gustharts states that a chin strap cannot be fitted to the Forest afterwards. Buy an Arborist if the work needs EN 12492. A strap added at home does not reproduce the kit that was sold with the Maclip fitting and the crash absorber. Keep the Forest for ground work, or replace it when the job changes.
Which visor comes with which kit?
UK model pages often include the coarser G16 with the Forest and the finer F39 with the Arborist. Other markets have sold both screens on both kits, so a photo can mislead you. One amazon.co.uk Forest title says F39 while the bullets say G16. Read the live description.
Which one costs more at a UK dealer?
In October 2026 a Forest sits at about £180–£190 and an Arborist at about £190 excluding VAT up to about £276. The Arborist is the higher shelf because of the strap, the crash absorber and EN 12492. Headers near £50, under either name, are unverified against that shelf.
