does it have a fleece or some liner in the inside of the glove, and does the zipper unzipp and how to keep it from unzipping?
JOSEPH I There's a thin liner but not fleece and I'm not sure why they call them waterproof since water does get through when submerged. But, I also have the 5mm 3-finger version of these I just took spearfishing in upper 50F water and I've had the 3mm out paddling a few times practicing my whitewater rolling. They keep your hands warm when wet and they've got good grip.
I've had no problems with the zippers unzipping. I think people might be trying to zip them over too many layers of other stuff. For scuba, I had them zipped over a 3 mil wetsuit. For paddling, I zip them over the wrist gaskets (pretty thin) but inside the outer drytop layer.
DANIEL L There isn't a fleece liner, but the inside of the glove is lined with a very smooth material that makes getting the glove on very easy. The zipper does un-zip easily if worn outside the wetsuit sleeve - - so I just zip them up & tuck them under my wetsuit sleeve.
DARRELL B The liner is the same as on the high-end Waterproof wetsuits, it's the "orange" material, with the "silver" material at the seals. The zipper zips and unzips, just like it is supposed to do. Mine stays zipped until I unzip it. Hope this helps.
JASON M Yes, the zipper does in zip, but up here in the puget sound I've never been cold. I put wax on the zipper every 3 dives and it stays put.
