Train Like You Race® With The SIM Pro II

The SIM is the first practical triathlon and swim training tool to mimic the body position and experience of a wetsuit swim by lifting you up — without overheating from wearing a wetsuit in an 80°F pool. This patent-pending suit is a game changer. It's better than a pull buoy, because it lets you kick and turn naturally. It's also gives just a touch of warmth for those cold morning workouts. The SIM makes every swim a race-specific training workout. Once you try it, you won't ever want to go back. Note, these shorts are designed for the pool and should have excellent durability if you rinse them after use with fresh water and dry them thoroughly.

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.

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 it 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.
