Hybrid base layer design creates three different zones that provide greater warmth where it is needed most, and greater breathability in the most critical area. The Tri-Tec Performace Base Layer Quarter-Zip combines Drake's EST, MST, and LST base layer fabric weights in distinct temperate zones:

- EST (5-ounce material) under arms and on wrists

- MST (8-ounce material) on fronts of shoulders, forearms, and side/kidney areas

- LST (10-ounce material) on torso and tops of arms
