  1. Do what they do, only better...

    Posted by Taylor O on 27th Jan 2019

    Ok, I'm not sure, but I just used the new ones today, and they seemed to last longer than the old ones...

    Either way - it's so nice to be warm.

  2. Excellent Customer Service

    I purchase a Thermalution shirt from this company. It had a flaw and was immediately replaced with another shirt that worked great. It has transformed my diving! No longer do I have to wear thicker neoprene (and carry more weight) to stay warm. I purchased extra batteries and the purchase was smooth, efficient and I had the spare batteries in just a few days. Thank you, HeatedWestuits.com, for an excellent product and superb customer service.

  3. Batteries and vest review

    Posted by Ken Hayduck on 4th Jul 2017

    The spare batteries have worked as advertised. Nice to have extras for a 2 tank dive. My only concern is with the connectors. I have used my vest at least once a week since mid may and with out any problems but, I am concerned with the longevity of the connection pins after repeated use and am concerned that they will break off. I would liked to have seen them a little more robust.

    As far as my 70M vest, It does add warmth as advertised but, is definitely not a cure all in 45 degree water, even under a 7 mil. Is it possible to have heating elements on the front side also? My biggest complaint about the vest is the color indicators on the controller. The orange and the red are too close in shade. You really have to focus as you go through the selections. It would have been better if the medium setting was yellow or perhaps blue.

    Overall, I am still glad I bought it.

  4. A must for a full day of diving.

    They are batteries and they work as advertised. What more can one say? :-)

  5. No dealer cost?

    Posted by steve weaver on 18th Jan 2016

    I didn't realize that you didn't offer dealer price on these batteries before we sold them. We will have to think twice before offering them in the future.

  6. Battery check

    So far so good. Kristi loved the fit and the warm suit in cold water.

  7. Love love love the thermolution shirt!

    Posted by Unknown on 28th Aug 2014

    Love the shirt! Worth every penny! And now that I have an extra set of batteries, I will always be toasty underwater!

  8. "Thank God"

    Own the 70m system with spare backup batteries. I am 68 years old and tend to get COLD even in 80+ degree temperatures after long exposures. I still push the limits on depth! Thanks to this system I can totally enjoy my long dives and extended hang times. The ease of charging, hooking up and unhooking the batteries is a dream come true. It looks good and feels even better. PS I even used it at a Penn State Football game with wind chill at below zero. Wish I had my new extra batteries.

  9. extra batteries - just in case

    Posted by Dora on 23rd Dec 2012

    You probably won't need the extra batteries, but just in case you are out diving and don't have a chance to recharge them. Thanks Matt for all of your help and your follow through! Suit and batteries arrived in time.

  10. No fun being cold on the last boat dive

    Posted by Mark Strovink on 10th Dec 2012

    Too expensive? Yes. But so is the shirt the batteries go with. Worth it to have my wife diving with me? ABSOLUTELY.

    Core warmers didn't work, Lavacore didn't work, fleece didn't work, only the heated shirt has made my wife comfortable on dives and surface intervals.

    On a liveaboard we recharge the batteries between the dives. On a 2 or 3 tank dive boat, my wife gets too cold once the batteries die. Now she can stretch her heating, and comfort, out for the duration.

    The extra batteries are the same as the well made originals.

    Did I wait for the batteries to go on sale? You bet I did!
