The SPIDI Frontier Thermorain motorcycle jacket is purpose-built for adventurous motorcycle riders seeking a combination of comfort and lightweight performance. This Thermorain variant of the motorcycle jacket offers excellent protection from the elements.
A large portion of the motorcycle jacket is constructed from Stretch Performance fabric, a nylon-based textile that includes 4% elastane. The result is a material that offers impressive wear and tear-resistance while remaining highly flexible. Add to that the inclusion of high-tenacity Tenax polyamide, and you’ve got a motorcycle jacket that defies the stiff, bulky feel often associated with adventure gear. The SPIDI Frontier Thermorain is significantly softer and lighter than you’d expect.
Despite its supple build, the motorcycle jacket’s medium-length cut and tailored fit make it well-suited to enduro and adventure riding—the kind of rides that really get the sweat going. Its slim yet accommodating fit provides comfort for a range of body types, from ‘average’ to more sturdy builds. The micrometric adjustment system (similar to a BOA dial) allows for precise tailoring at the waist, while elasticated inserts at the forearms help keep the elbow armour securely in place while riding.
Two chest panels equipped with magnetic opening systems allow for easy adjustment of ventilation—even on the go.
As with most of SPIDI’s range, the STEP-INWEAR system allows for modular layering. You can further enhance weather protection by adding optional waterproof and thermal liners. In this setup, the Thermorain membrane is included as standard in this Frontier motorcycle jacket, offering reliable waterproofing and wind protection out of the box.
Rider-friendly innovations boost usability on the road: a comfort-focused ergonomic collar and an ergonomically curved YKK front zip are both distinctive SPIDI design elements.
The Frontier motorcycle jacket comes equipped with removable Warrior Lite protectors, EN 1621-1 Level 2-certified for the shoulders, and Force-Tech armour at the elbows. The jacket itself meets EN 17092-3:2020 Class AA standards, ensuring a high level of protection in line with EU motorcycle gear regulations.
You’ll find seven external pockets, including a large rear pocket—plenty of room for essentials. 3M Scotchlite reflective detailing improves visibility during night riding.
A connection zip allows you to pair the Frontier motorcycle jacket with the matching Frontier motorcycle trousers—or any other SPIDI motorcycle trousers equipped with a compatible zip.
