Had a couple days with my order of two 16oz gloves from TopBoxer. Going to do a review later, but for anyone that might be thinking of making an order:
I don't recommend IMF for bagwork or pads unless you are a particularly heavy hitter and your knuckles just tear through the padding of these gloves, then get dense IMF, ask for thicker than standard latex foam or othopedic foam.
I reviewed some more dense IMF gloves here

And those did actually protect very well for bagwork and pads, and would absorb some shock, but I think the formula has changed now to prevent the bobbling that used to occur. The last very dense IMF gloves I had from Beaulieu did not feel as good on the bag and I gave them to a friend. Maybe that was because they hadn't broken in, but regardless I'm still of the opinion that latex is the way to go.
The gloves I've just received are soft IMF and they don't feel like they absorb any shock despite it, it sort of just compresses back against your fist and doesn't make for a very comfortable experience. Dense IMF will also have better wrist support.
Dense IMF may actually protect well for bagwork but I think you can do better from Beaulieu. My 10oz layered latex foam glove from Beaulieu offers me better protection on the bags and pads than any of the 5 Beaulieu IMFs I've had do as far as shock absorption goes, and hasn't degraded at all after a year of heavy use.
Soft IMF is great for sparring and safe for you and your partner, but not ideal for padwork or bagwork, in my opinion.
Just my opinions on the experiences I've had. Others might think differently.
Also, the 360 velcro straps do nothing for the wrist support. All they do is add weight onto your forearm.
