Performance Base Layers

When it comes to completing tasks at hand, clothing choices directly impact that work’s quality and efficiency. What was once considered a simple matter of comfort is now understood that properly layered clothing systems affect performance. Modern base layers are multi-faceted performance garments that lay the foundation for a clothing system, and the folks at Massif® have set the bar high. Their base layer collection keeps the wearer comfortable and dry and protects from heat and flame exposure.

Cool Knit®– Lightweight

The perfect base layer, Cool Knit®, aggressively wicks sweat away from your skin, keeping you cool and preventing saturation. The lightweight four-way stretch retains its shape over time and is highly compressible for easy stuffing when you’re living out of a pack. Constructed with DuPont™ Nomex® brand fiber – the first flame-resistant fiber selected for use in military uniforms. DuPont™ Nomex® fibers carbonize and thicken when exposed to the intense heat of a flash fire, creating a protective barrier that reduces or prevents burn injuries. The Cool Knit is so soft and comfortable that you’ll forget it is Flame Resistant (FR).

Nitro Knit – Lightweight

The Massif® Nitro Knit base layer with 37.5™ technology offers no-melt, no-drip protection for day-to-day activity. The extremely lightweight and breathable fabric works with body heat to dissipate moisture keeping you dry and comfortable. These next-to-skin base layers have a performance fit and multi-dimensional stretch for ease of movement and layering.

Protective Combat Uniform (PCU) – Lightweight and Midweight

The PCU is the moisture-wicking, next-to-skin layer in the complete PCU survival system. Developed for USSOCOM, Massif® utilizes Polartec® Power Dry® to provide superior wicking action, an ergonomic design for exceptional fit, smart seam integration to eliminate pressure points from stacked seams, high breathability, quick-drying, and comfortable next-to-skin. You’ll want this Non-FR layer in your kit.

Inversion – Lightweight and Midweight

One-touch and you’ll be sold. A few cycles of wear, and you’ll be touting your new favorite base layer. The Massif® Inversion base layers utilize an advanced tri-blend yarn system that provides unparalleled performance across multiple environments. This unique blend plus the addition of spandex generates an improved range of motion, superior comfort, and remarkable recovery for after-wash durability with no unsightly “bag outs.” Sweat is rapidly wicked away from your body through a premier moisture-management system scientifically engineered for fast dry times. This moisture-management system results in a highly breathable garment that allows you to focus on your mission.

HotJohns® – Midweight

The HotJohns® base layer is a versatile piece worn next to skin or over a Massif® Cool Knit® layer. The design is streamlined for easy layering and is highly breathable, wicking moisture away from the skin, keeping you warm and dry even when you’re working up a sweat. Extra length in the back keeps the torso tucked in without excess bunching. Constructed with DuPont™ Nomex® brand fiber, HotJohns® will be a favorite in your layering system.

Flamestretch®– Heavyweight

Massif’s warmest base layer incorporating DuPont™ Nomex® brand fiber is an insulating layer worn over Cool Knit® and HotJohns® garments. Flamestretch® fabric is highly breathable while trapping heat to keep you warm and comfortable. When operating in cold conditions, these ultra-soft and incredibly comfortable garments are the ideal choices.
