Lightweight describes the fabric, not the feature set. These pants have all the function of their full bodied cousins, built using a light weight ripstop fabric. At 6.5 – 7.5 oz per square yard, you will find lightweight pants more breathable and comfortable to wear. Lightweight pants exploded on to the tactical scene with the introduction of the 5.11 TacLite Pro, and now most manufacturers offer a warm weather variety. Here you’ll find the lightweight offerings from every major tactical collection.
