Randy, not sure about lighter, I'll let you know when I get mine in the next couple of weeks.
As Curt said, some pretty cool stuff in this year's additions/changes to the line.
Sitka Gear new products While always pushing the edge on development, Sitka Gear also really applies the input from the field. For instance, they've added leg zippers to the new storm front/cold front pants and the celsius bibs. Numerous changes this year have been brought about through real world testing of the previous products.
I was sold while using the Mountain Mimicry pattern during season. Previously I had been a Predator man but MM proved to be just as effective and on far better clothing than I had previously owned. I'm really interested to see how the new Opti-fade pattern does with all the research that's standing behind it.
As you've already found, for those of us that hunt in the heat, the light products are the bomb. I soak my traverse beanie and core zip-t, wring them out and stay cool no matter what the heat. The great wicking properties of Sitka gear make the evaporation quicker than off your skin which is a huge plus when you hunt high heat like those of us down here do. I showed Bob Walker in Texas and he was floored how well it worked.
I'm also looking forward to the balaclava; I like to wear face covering and think this one will stand out as the other products do. The new insulation layers and the Dutch Oven/Ardica vest should really improve the cold weather system for those that hunt in seriously low temps or those like me that get cold easy.
