These are the A8 Insulated Shorts by Beyond. Their Climashield® Apex™ insulation provides comfortable warmth for your critical bits on cold missions without hindering your mobility. Especially great if you need to lie flat on cold ground while spotting the enemies or observing your surroundings. Made in the USA.
These thermal shorts are designed to protect the nether region of the US soldiers from cold and misery. You don’t need to restrict your movement by wearing full-length insulated pants. Simply pull these on top of your other pants, and you will warm the essentials.
In the civilian world, hunters and nature photographers can do the same when sitting in a wintery blind. As can those riding a snowmobile or otherwise appreciate warmth in the right places.
These are made in the simple sizing system. Note that since these are supposed to go on top of the other layers, the sizing is quite ample. Below, you will see the waist circumference of the different sizes. The waist has a velcro adjustment, so you can tighten it slightly from the given measurement.
Unissued US military surplus. Some of these are still wrapped in plastic. In other words, the price is very nice considering that these are unused high-quality warproof military gear made in America.
