These shorts are a durable and can help you cross the finish line with ease. With buoyancy built in the correct areas to help you while you're in the water, this is a bottom that you can feel confident while in the water.
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 degree pool.
It's better than a pull buoy, because it lets you kick and turn naturally.
It also gives just a touch of warmth for those cold morning workouts.
The SIM makes every swim a race-specific training workout.
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.
