Hi Mike,
Both vests are great options. The FIR system from Ursuit runs on an internal battery pack while the Santi runs on an external power source. The benefit to that is longer heat times depending on the battery that you have. The Santi also has some density to it. It is a 210 gram undergarment. So even with out the heating element, it is still a fairly warm undergarment. the FIR system, is great because of its intensity options as well as its internal rechargeable battery. Either way you go, they are both great options!
