As there are absolutely no reviews of this thing out there that I can find I figured I'd add my two cents for anyone out there considering buying one. I bought it sight unseen from an LDS on pure faith that Apeks got it right. They were just released. I just completed my second dive with the Black Ice today and had a good time with it. Most certainly beats the crap out of rental gear. I'm 5'10", 165 lbs, 30" waist, using a 3mil wetsuit. I have the small/medium. I absolutely love how adjustable this thing is. It can be adjusted (with screws and grommets) at the shoulders and waist. This is very good for me as I'm long in the spine and narrow at the waist. Although, I have to say that to make it a perfect fit for the shoulder pads I'd need to add about 3 inches to the shoulder straps at the top, as the top D ring sits about at the peak of my shoulder. The waist adjustments were set all the way in and were perfect for me. It is a little bit hefty, but I sorta like that because it really feels like there's no way to break it. It also stays put really well. Not as tight as a backplate, but better than your typical BC. The fold out pocket on the left side is great. The pocket on the right spontaneously opened up on me today, though luckily nothing was in there. I'll have to figure out what to do about that. When i have time I'll post some pictures of all the nooks and crannies. If you have any questions feel free to message me or post back. Hope this helps!
