Entry system is water tight, easy to get into. Knees are high tech, not bloated real comfortable. The neoprene and 3D design is off the chart stretchy. I wear my suit kayaking, surfing and wakeboarding. I will be wearing it kiteboarding too in the spring. My son's and I all wear this suit, it takes minutes to put in on and I don't sweat like I use to in my old wetsuit. WORTH EVERY CENT.
