Massif® utilized our combat shirt expertise and developed the Caldera Wind Shirt. This shirt features Massif Battleskin™ fabric in the torso for exceptional breathability and real FR protection, without sacrificing durability. The wind-resistant sleeve fabric, SABA®, is a revolutionary new two-layer laminate system that combines proprietary FR processes with unique knit structures. Massif SABA fabric is lightweight, has exceptionally high breathability, and an advanced Durable Water Repellent (DWR) treatment, making it perfect for under-armor applications and advanced layering systems. The proprietary knitted nylon face has an extremely smooth hand, adding to its next-to-skin comfort and enabling quiet operation.

Wear the Caldera Windshirt with lightweight or mid-weight base layers or as a stand-alone garment for year-round use. Compatible with backpacks, chest rigs, and parachute harnesses, this shirt offers world-class performance for a variety of activities.

Excellent Shirt.

Serious, high quality shirt. Has all the many features as described. The sleeves are wind resistant & protective, and the torso is soft & breathable. I really like it.

I ordered too big (my fault--was thinking cotton shrink), and customer service immediately exchanged my size--excellent service.
