Think about it how many different manufactures of guide gear ? there are three car battery makers out there. I have just recommend this set to a friend this weekend.You can pay more for just some jackets not me but just say en it covers all the bases for starters. I own the Vexilar suite with Under armor cold gear and then cold gear 3 and all done. Cost a bit more then the Hy creek ice suit package by about $190 as I have it figured.
