  • 11/24/2013 Increases V02 Max and Maximizes Performance.

    5 Review stars By Trainfriend

    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.

  • 7/31/2011 Great little add on

    5 Review stars By Robert D.

    If you already got the snorkel, this will give a more added pleasure. Works your cardiovascular conditioning to another level. I enjoyed the challenge of gasping for air but was able to overcome it after prolonged use. Now it just sits on top of my snorkel, and I do not even know if I can remove it. Recommend this!!

  • 9/24/2010 Check Plus!

    5 Review stars By Heather M.

    This thing is killer! I have been swimming for years and always wondered what it felt like to have limited oxygen like training at altitude. I think this is great. I would recommend it to serious swimmers who are already fit and looking for that little edge.

  • 7/27/2010 you won't notice right away

    3 Review stars By Andrew W.

    It was a bit wierd to put it on the snorkel but once I got it on it stays on even in my bag with all my other swimming stuff. You don't really notice a huge difference right away but once I got into a longer set I started wondering why it was harder to breath and didn't remember having it on until that moment

  • 4/10/2012 Increased lung capacity!

    5 Review stars By Carlos

    Well worth the price. I had to go to a pulmonologist for a check and he found my long capacity to be 30% larger than people my age, weight and height. A year prior that wasn't the case. That's a WOW for a TRI-athlete!!!



  • 10/18/2010 FINIS high altitude/ cardio cap

    5 Review stars By Rob

    I recently bought this to add to my FINIS snorkel. If you train for running swimming tri's this set up is great it will train you to function at a higher level on less oxygen. So when you are actually running in a tri or just for fun you preform better with an abundant amount of oxygen. I have noticed a lot of positives effects from using the snorkel and the cap has really helped my endurance all around



  • 5/15/2014 Nice addition

    4 Review stars By Dzonkey

    Fits firmly over the top of the Finis swimmers snorkel, and closes off about 40% of the snorkel opening. Works fine as I swim several miles per week for exercise and can use the added breathing exertion.



  • 3/21/2014 Good but could be better

    3 Review stars By Luke W.

    It took some serious work to install this onto my snorkel. It didn't slide on as easily as I thought it would.

    Once it was on, it does provide decent resistance for your breathing but not a significant amount. My first practice with it, I could feel my lungs working but didn't stress them to the point I would prefer.

  • 9/28/2012 cardio cap

    3 Review stars By xx

    I don't really know if this help. It seems to have the same opening as the snorkel so I cannot see the benefit of it.



  • 4/11/2012 You need this

    5 Review stars By Bryan J.

    This device you cannot go without it really get the most out of the use of the snorkel. Although you have to really push in down on the tip of the snorkel or else you will loose the tip, like i did. Thankfully i was able to get it back both times. Just check it before using it daily and push on it to secure it staying on. Other than that i Love this add-on.

  • 10/16/2010 Cardio Cap = Death

    4 Review stars By Marissa

    Wow. When i first put this on my snorkel i was pretty much gasping for air after a 500. After about a weeks use though, it gets easier and does increase lung capacity. kind of hard to put on though. At lest it's not tape with holes poked in it anymore!



  • 6/15/2010 Helps runners too!

    4 Review stars By Edward M.

    I have started training with this cap 3 wks ago and I can feel a difference in my swim as well as when I am running. I would try to run with this snorkle on if I wasn't so vain.

  • 5/30/2010 Waste of money

    1 Review stars By Mile High Swimmer

    The cardio cap never fit well onto the snorkel. Within a week, it fell off somewhere between home and the pool and was lost. Would not recommend unless you like to throw away your money.

    5 Review stars By amp1515

  • 2/5/2010 Useful accessory

    5 Review stars By Michael R.

    It works well. After weeks of using the Cardio Cap I've noticed improvement while swimming: slower heart rate and easier breathing. It also makes it easier to discharge water without using hands.

  • 2/4/2010 Finis Cardio Cap

    4 Review stars By Chris T.

    Attached to my Finis Snorkel very easily and stays on no problem (even when my 6 year old tries to rip off). You can really tell you actually have to breathe diferently. I recommend it as I run ultras and anything I can do to assist with breathing is HUGE. Go buy this.

  • 4/7/2009 Just OK

    3 Review stars By Michael K.

    I actually noticed only a slight difference with the cap on. I swam a mile and had to actually concentrate to notice any difference. Maybe my breathing is less intense than others when I swim.

  • 4/2/2009 Good addition to Swim Snorkel

    5 Review stars By M.

    The Cardio Cap is a great addition to my Swimmers Snorkel. Reduces my air intake and makes me breath harder during workout. When i swim without it I notice a big difference. I use to take a breath every stroke now i take a breath every other stroke. Im not giving all the credit to the Cardio Cap but it certainley helps.

  • 3/16/2009 Lets me focus on form - get nose plugs

    4 Review stars By DSE

    Good snorkel, although I am not comfortable without nose plugs. Sometimes wish it curved back a little more as if I am looking straight down at the bottom of the pool and "swim downhill" or "press the buoy", I can start getting water in it. But 95% of the time it is fine. Maybe should have gone with the free style snorkel.

    Easy to install. I am beginning to tell a difference. The cap also helps keep water out.
