Morgan Classic MMA Gloves

They're comfy, easy to put on. Perfect for what I needed.

Awesome Products

Very happy with these items I gifted for myself. Great price, quick delivery and great communication with the tracking of my goods. I’ve been using my boxing bag since I received it and I’m loving it. Great way to keep fit.

SMAI Rattan Tactical Walking Cane

An excellent product, lightweight but strong, perhaps a bit too much flex for me as a disability cane, but awesome as a tactical cane. Service was great and came well packaged. Very happy

This bag is so freaking good

This bag is REALLY HEAVY & HARD.
I'm 180cm, 75kg, and 150cm bag is perfect height.
The bag holds very well, minimum swings, I don't know what stuff they put inside, this thing is hard enough to even conditioning my bones, and will definitely strengthen my punch and kicks, beautiful bag, highly recommend!!!

Best bet MMA Direct.
