Just get a pair of Twins if you are kickboxing. You will not be disappointed.
There's a reason why every single Muay Thai fighter use Twins. I've seen a lot of other gloves, but none of them come close.
As bag gloves, it doesn't matter a whole lot whether you get boxing or Muay Thai gloves.
The only other glove outside of Twins that I like are the Gorilla Gear's Hitman Gloves:
They are 16 oz but sized slightly larger than 10oz gloves. Most of the padding is in the knuckles. I use it for sparring only because it simulates fighting with 10 oz gloves. These gloves are styled as Kickboxing gloves.
