Building on the success of our popular men’s jacket, the Catalyst vest delivers durable breathability in an even lighter package. Silent, breathable, insulating, and engineered to stretch and move with you, the Catalyst changes what is possible in a softshell garment. The revolutionary, 2-layer construction creates a vest that is warm and breathable while also being lightweight and completely silent.
Interior 37.5 fleece lining works to optimize your body temperature while the brushed, durable exterior is ultra-silent while fending off moisture through our advanced DWR.
The result is an ultra-versatile vest that performs as well in the stand as it does in the backcountry. Whether you are looking for silent warmth during the roar or hoofing it through knee-deep snow on a late-season tahr hunt, the Catalyst softshell system vest will help you get it done.

- Exclusive 37.5 Active Particle Technology

- Revolutionary, 2-layer softshell design
- Ultra-quiet construction
- Built-in stretch for full range-of-motion
