Windstopper Lining

It works with all models of UF PRO Striker and P-40 pants (except Striker ULT and P-40 Shorts). You can add the lining to upgrade your pants’ thermal properties at any time. It’s easy to do. Just position the lining along the upper edge of the pants and zip it into place.

Determining the width of the lining is easy, since it comes in sizes that correspond to those of the pants. Simply look at the label on your UF PRO pants to see what size they are if you don’t already know. The size on the label will be formatted with a letter followed by a number, a slash mark, and another letter.

For example, the pants label might say  W28/S or W28/L. Here, the W stands for waist and the 28 stands for the waist size in inches. Meanwhile, the S stands for short leg length and the L stands for long leg length. So all you would need to do is pick a lining that’s either a 28 small or 28 long to go with those particular pants. 

That depends on your activity level and on the amount of heat your body produces. During medium intensity activities,  a WINDSTOPPER-lined pair of Striker or P-40 pants should keep you warm up to -10 degrees Celsius.

No. The liner features antistatic construction, meaning no clinging to your body due to the presence of charged electrons. Also, the WINDSTOPPER liner won’t impair your movements—thanks for that goes in part to its anatomic fit, which mimics that of the pants themselves.
