About this 

Set of 3 TEST Extra-Large Protective Combat Uniform PCU Gen II Level 1 Silk Weight Short Sleeve T Shirts:

Special Operations Forces (SOF) needed a lighter, more efficient clothing system designed for a wide range of weather conditions, from mild temperatures to the most extreme winter conditions. HALYS brand gear answered that call. Our gear has far less weight and bulk when compared to previous outdoor clothing options. Multiple high-tech fabrics are incorporated into the HALYS brand to achieve maximum performance. This complete layering system has been successfully tested in temperatures ranging from 60° to -40° F and is designed to withstand the rigors of mountaineering, backpacking, and climbing in a wide range of temperatures.

3 Test T Shirts as shown, all size XL, all look unused - near new, Type A, Type B & Type C.  We have typed the test letter of each t shirt so you can identify which is which, the type letter is NOT written on front of T Shirt 

The HALYS brand gear is a multi-level garment layering system designed and engineered using innovative construction techniques and multiple high-tech fabrics including Polartec® Power Dry®, Polartec® Power Dry® with X-Static® and Polartec® Thermal Pro® High Loft.

When combined with the other levels of the Protective Combat Uniform (PCU) system, this garment collection offers the wearer less weight and bulk of traditional outdoor gear, and enables the wearer to customize the uniform to meet the varying demands of adverse weather conditions. Standard Color is Coyote Brown.

• Type A and Type B are the same silk weight with Type A being slightly darker color of coyote brown that was settled on coyote brown #499, both are a silky slippery fabric with rounded longer back hem & looser fit, NOT compression fit
• Type C is the model released as standard PCU Gen II Level 1 T Shirt, coyote brown # 499 with more of a cotton-ish feel, made of 97% Polyester and 3% Silver Coated Nylon
