FinisFINIS Cardio Cap

I'm a big boy and not an Olympic Athlete by any means @ 6"0", 315lbs. I swim 1.5-2 miles 6 days a week. I swim with a Polar FT80 Heart Rate Monitor. My average heart rate, without a Cardio Cap, went from about 133 BPM down to 115-117 BPM during regular prolonged lap swims. After installing the Cardio Cap on my Finis Snorkel, my heart rate went back up to 128-130 BPM indicating more load/stress due to decreased oxygen flow. After two weeks with the Cardio Cap I now routinely record 115-123 BPM during the same length/time lap swims. I can now swim faster, stronger laps without the use of a snorkel. My heart rate barely rises above 110 BPM and I've shaved almost 5 full seconds off my average lap times when swimming without the Cardio Cap. All of these factors indicate to me that the Cardio Cap has greatly improved my V02 Max and maximal performance in the pool. For a serious athlete training for a triathlon or swim team, I highly recommend this cap.

I bought this the same time I bought my snorkel. I haven't really use my snorkel with out it. So I can't really compare with or with out, but it has had some great benefits. I have definitely seen an increase in breath control. It dose keep a certain amount of water from going down my snorkel. For the price it is worth trying. I don't see any down sides to it. If you are putting in an order for a snorkel get the Cardio Cap too. Oh and don't worry about it being white and not matching your black and yellow snorkel. They are Black now. Happy Swimming
