A 3/4 length ends the Le Bent Heavyweight Grid Fleece 3/4 Bottom below the knee, so the hem clears the top of a boot. This base layer bottom is cut to fit slim, with panels sculpted to follow the leg. What Our Gearhead(R) Experts Are Saying:"Walking from the car to the boot pack on cold mornings, the grid interior held its warmth against my legs, and the cuff sat clean inside the boot without bunching. My legs felt the same at the end of the day as at the start."
