This is review of the Navigator and Reactor Gloves.
Navigator 2004 Model (Pre-Titanium). Glove is well made, anatomic curve, and tough griptite palm. The 2.5 mm Neoprene makes them warm to about 50 F. Anything below that and your hands may get cool/cold. I have worn them to water temps around 65 deg F before they start to get too warm. Good Glove for the Money (~$26)
Reactor Gloves add another 0.5 Neo and Titanium particles for added warmth. Gloves probably are good to around water temps of 40 deg F and cold air. Good grip, well made, yet not too bulky or stiff. A very good alternative to mitts or Poagies for cold wether paddling. Probably to warm over water temps > 55 deg F.
