Efficient keyless system for quick fin installation and release. The FCS II system requires no grub screws or keys to secure the fins to the board. Fins can be easily inserted and removed in seconds, allowing you to adapt your equipment to the conditions, on land and in the water. Recessed leading edge with flush base connection improves water flow. These features not only create a sturdy anchorage to the board, but minimize water disruption through a more flush and seamless transition between the fin and board surface.

The FCS II System is backwards compatible with all your favorite FCS dual tab Fins. Constructed using a corrosion resistant titanium tension rod, and a rotating, wear-resistant polymer barrel.  When the fin is inserted into the plug the barrel interacts with a groove detail in the fin to lock it into place using a combination of downward and lateral force.

Lightweight Composite Frame encapsulated by high density foam reduces weight and maintains flex.

  • Center - 1 plug (Box) only
  • Side Set - 2 plugs (Boxes) (left and right - only sold as a pair no singles)

Great Option for older, beginner workouts
Color: Gray, Style: Yoga Mat
I am a 54-year-old woman with multiple issues dealing with my weight, knees, and hips. The support of this particular mat is thick enough that there is no pain when being on my knees or lying down. It does not pinch your pressure points, causing pain as a thinner mat would. I am very pleased with the quality of this mat; it feels durable and I do not worry about my flopping around and destroying it while I learn the proper positions I need for my exercises. The length and width is sufficient for my 5 foot 11 inch height and extra girth. I was not looking for anything in particular in terms of design or color, as I prefer functionality, and this is to be used at home as a beginner mat while I start my exercise program.

Great Quality Mat for the Price
Color: Gray, Style: Yoga Mat, Color: Gray, Style: Yoga Mat
After burning through several cheap mats that curled, bunched, or wore out within weeks, this one finally got it right. The 1/2-inch high-density foam provides real cushioning, my knees and wrists feel the difference immediately, and it holds its shape without feeling unstable during balance poses. Grip is solid on hardwood and carpet alike, and the included carry strap is a small but genuinely useful touch that makes hauling it to the gym effortless. It's a bit bulky for travel, but for home or gym use it's hard to beat at this price. The quality speaks for itself, this feels like a mat built to last. Highly recommend.

This is very good
Color: Purple, Style: Yoga Mat, Color: Purple, Style: Yoga Mat
It’s a really good size and quite soft; the only downside is that I think it’s a bit pricey. It’s a good option if you don’t have other choices, but if you can find something better, do so.
