ROKA SIM Pro Shorts 2015 – Women’s





Our patent-pending ROKA SIM Pro training shorts were built from the ground up, adding in only what’s needed to help you train like you race. The SIM Pro mimics the effect of our Maverick wetsuits by lifting you up in the water. Our RS2 technology, which adds buoyancy to the centerline and removes it from the sides, promotes correct rotation, and Yamamoto’s SCS coating gives the SIM a faster-than-skin nano coated surface. Perfect for racing or training. These shorts can be worn in open water or the pool. We expect them to have excellent durability over time if you rinse them with fresh water after use and hang dry them thoroughly (don’t use a dryer). An occasional rinse with wetsuit shampoo will help to remove chlorine and extend the life of the suit.


Improve Your Technique – If you want to swim faster with less effort, then rotation matters a LOT.  A fast freestyle requires effective rotation along your centerline to generate power and speed in the most propulsive phase of your stroke.  The Maverick Pro leverages basic laws of physics.  We call our application of those laws “RS2” – the ROKA Speed Stripes.  It’s science, and it will make you faster.

The majority of the suits on the market get this problem dead wrong.  We did a LOT of trial and testing to get this right.  Many suits, even the most expensive, add buoyancy to the lateral or outside parts of a wetsuit, but using basic physics, it’s easy to see that is is the equivalent of adding weights to your cycling shoes and pedals!  It inhibits the power phase of your stroke, makes it really hard for you to rotate properly, and makes you expend more energy.  Our patent-pending suit design enhances the power phase of your stroke and encourages quick, easy rotation along your centerline.  And if you over-rotate when you swim, you will be able to feel that more easily in our suit.  All of that translates to faster swimming with less effort.

Get The Fastest Body Position – The SIM Pro lifts up your hips just like a wetsuit, putting you in the fastest position possible and helping your body develop the muscle memory you need on race day. Most top wetsuit manufacturers focus on buoyancy alone.  Sure, wetsuits help lift you up, but that’s not enough and in some cases it can really get in the way of fast swimming. To get the fastest body position, you have to remove buoyancy, mass and resistance from the places you don’t want it. With the SIM Pro, we add buoyancy to the hips and legs, creating the fastest position possible.  We also use Yamamoto’s SCS coating to further reduce form drag.  We’re confident you’ll feel the ROKA difference as soon as you jump in the water.

Yamamoto – For the SIM Pro, we use the exact same materials as its big brother, the Maverick Pro Fullsuit. This provides the exact feel you’ll have on race day. “Training Like You Race” begins with developing precise muscular and neurological adaptations the SIM Pro lets you do that.

The SIM Pro is 100% premium Yamamoto neoprene from Japan.  We use Yamamoto #39 SCS coated neoprene in varying thicknesses and use Yamamoto’s Aerodome neoprene on the centerline (front and back).  #39 is a long-time favorite in premium triathlon suits and offers an excellent balance of performance and cost.  SCS is Yamamoto’s proprietary hydrophobic surface coating.  Aerodome is a sandwiched neoprene that contains a perforated layer between two solid layers.  This composition traps air inside little chambers and improves buoyancy while reducing weight.
