The Alpinestars Honda T-Jaws V4 is a waterproof textile motorcycle jacket built for sport riders who ride through wet weather and cool mornings. It uses a 600D and 450D poly shell with stretch softshell at the shoulder blades, CE Level 1 Nucleon Flex Plus shoulder and elbow armor, GP Lite shoulder reinforcements, and a removable fleece-backed thermal liner. It is Tech-Air Ready, so it accepts Alpinestars' airbag system. Riders rate it well for fit and wet-weather protection; the main trade-offs are its sport-cut fit and the fact that back protection is not included.

Owners rate it 4.4 out of 5 across 11 ratings. They like the fit, the wet-weather protection and the warmth from the liner. Complaints center on the snug sport cut and the extra cost of adding a back protector.
The T-Jaws v4 Waterproof Jacket is a race-derived textile jacket for sport riders. It has a revised sport fit and a 3D pattern silhouette. The extended back gives more coverage in the riding position.
The main shell is abrasion resistant and made from a blend of 600D and 450D poly fabrics, with stretch softshell on the shoulder blades for freedom of movement. A fixed waterproof membrane keeps out wet weather. A removable fleece-backed thermal liner adds warmth, with 100g insulation in the body and 80g in the sleeves.
Zippered air vents on both sides of the torso let air flow through all layers, including the fixed waterproof membrane, when opened. Cuffs and waist have volume adjustment. A pant connection zipper gives a secure fit and helps prevent wind ingress. Reflective detailing sits on the lower back and lateral sleeves.
