## Overview

The JSP EVO ALTA Skyworker is a mountaineering-style safety helmet engineered for professionals working at height. Certified to EN 12492 and EN 397 standards, it features a lightweight, ventilated EPP liner for superior shock absorption, an adjustable 4-point chinstrap with a Revolution Flex wheel ratchet harness for a secure, pressure-free fit, and dual ventilation that reduces heat buildup by 2-3°C. Its modular design supports accessory integration, making it a versatile, all-round high-impact protection helmet designed for comfort, safety, and adaptability.

## Description

From the manufacturer Features EPP LINER EVO ALTA Skyworker features a lightweight, ventilated EPP liner to increase shock absorption and penetration protection. 4-POINT CHINSTRAP The helmet's 4-point chinstrap is easy to adjust on the head. Size and anchorage point adjustment offer a tailored fir for different head sizes. DUAL VENTILATION Side and rear ventilation in the helmet's shell and liner reduce temperatures by an average 2-3 degrees. INCREASED AIRFLOW EVO ALTA Skyworker is designed to keep the wearer cool. The textile suspension harness creates clearance between the head and EPP liner, increasing airflow within the helmet shell. SECURE FIT The harness cradles the head to keep the helmet stable with an adjustable 4-point chinstrap for increased security and 3D-Adjustment depth settings to enable a precise fit. MAXIMUM COMFORT The Revolution Flex wheel ratchet harness eliminates pressure points to provide maximum comfort, with a replaceable Chamlon cotton sweatband.

Review: Value for money - I recently purchased the KASK Superplasma PL EN 12492 Anti-Fall Helmet, and I’m thoroughly impressed! The build quality is top-notch, with a sturdy yet comfortable design that feels secure during use. The ventilation slots are a great touch, keeping me cool on long shifts. The adjustable straps make it easy to get a perfect fit, and the overall weight is surprisingly light, which is a big plus for all-day wear. Highly recommend this helmet for anyone needing reliable head protection—worth every penny!

Amazing product , very lightweight , would recommend some additional padding but apart from that its top of the line

### ⭐⭐⭐⭐ A little pricey but good
*by J***E on 19 March 2025*

Although this is a little on the pricey side compared to a lot of safety helmets, it is probably the most comfortable safety helmet I’ve owned which is what I wanted, that and no peak as I think peaked helmets limit your field of vision.
