This is a great value set including the BURTLE 005-IC101S Peltier 3-piece vest and battery set, plus a conversion cable for a spare battery and a limited-edition BURTLE tote bag. (The spare battery has been removed from the set. It is not included. *The original battery is included.) The vest size is "F". The product will be shipped in its original box. The [one BURTLE limited-edition tote bag] that came with the purchase is also included. (Unused, cool design!) I bought it two weeks ago for golf. I used it on the course last week. I felt the cooling effect, but it felt a little awkward during my swing, so I decided not to use it. Personally, cooling around the neck seemed like a good idea. I will also include a BURTLE conversion cable for a non-BURTLE battery as a bonus. (Please note that the operation is not guaranteed.) This is a used item that has been used once, so please understand that no returns or refunds are accepted.
