LIMITED EDITION. The ASSOS x Mammut TACTICA JERSEY is an off-road layer engineered for high-intensity gravel riding in hot conditions. Refined with ultralight, ultrabreathable textiles and five pockets for expanded storage.
The new TACTICA Jersey T5 combines the storage capacity of off-road equipment with the cooling breathability and streamlined construction of road-racing equipment. The TACTICA T5 stores more fuel for ultra-distance riding, creates more airflow for hot temperatures, and carries less weight for all-day epics and the long, grinding climbs that define gravel racing. A unique design was engineered for the shoulders, sleeves, and collar to ensure full, deep breathing during high-intensity efforts and complete freedom of movement, both of which are critical for off-road races that require punchy accelerations, feature hiking sections, and can keep you in the saddle for 10 hours or longer.
TECHNOLOGY
FEATURED FABRICS
The body textile is Trigger, a highly elastic circular knit designed to maximize cooling breathability in hot off-road conditions. Sens-AIR, an ultralight warp-knit mesh, adds muscle-wrapping support, cooling airflow, and UPF 50+ across the shoulders and sleeves. A rear panel of Stabilizator V11—the lightest, most intercooling of our stabilizing textiles – supports the expanded pocket storage capacity.
CONSTRUCTION/FIT
The TACTICA T5 mobility-enhancing fit is less aggressive than ASSOS racingFit, balancing streamlined, low-volume aerodynamics with multi-hour comfort and less restriction off the bike.
ENGINEERING
Raw-Cut Sleeves: Race-inspired construction that eliminates transitional ridges for clean lines and aerodynamics.
Five Ramp Pockets: Flexible fabric panels create “lids,” securing and stabilizing pocket contents with expanded capacity for ultra-endurance riding.
Reflective Detailing: Reflective elements on the pockets increase visibility in the low-light, overcast conditions when wind and rain protection are most valuable.
