Hello ! I have planned to buy a pair of Rival Ultra (RB1) bag gloves and a pair of Rival High Performance (RS2V) for my boxing training. I'm no boxing expert, that why i ask this question. There is no all purpose glove right ? Beacuse i just run over a Fairtex glove (Fairtex Thai Style Training Gloves) and in the description it says "All-purpose training gloves perfect for sparring, bag and pad work". I mean a heavy bag glove is to stiff/hard to sparring with and a sparring glove is to soft to workout on a heavy bag with (will worn out faster), or ?
