DESCRIPTION
CRAZY's Shirt Acceleration is the most technical mountain t-shirt in the line, developed for those who tackle high-intensity activities at altitude: trail running, fast alpinism, skyrunning, or challenging hiking in the warm season.
Fabric and technology
The main body is made of Performesh+, a highly breathable mesh fabric that combines lightness, active ventilation, and quick-drying properties, keeping the body cool even during prolonged exertion. The shoulders — an area subject to heat and friction from backpacks and harnesses — are reinforced with a Graphene panel, a thermal conductive material that effectively dissipates body heat and increases abrasion resistance at the most critical contact points.
Key features
- Main fabric: Performesh+ for quick-drying and high breathability
- Shoulder reinforcements: Graphene panel for thermal management and resistance
- Construction: ergonomic design for freedom of movement
- Ideal use: intense aerobic activities in high mountains, from trail running to light alpinism
The result is a t-shirt that makes no compromises: it doesn't weigh you down, doesn't retain sweat, and protects where needed, making it a solid choice for those who want real performance when the altitude increases and the effort intensifies.
