hey I am new here, but here goes....
Have a very close look at flyfishing equipment. Especially that from Canada and the US, its designed to be comfortable, be worn long distances, ergonomically balanced and look after the 2nd mortgage equivilency of equipment. In all parts of the world where flyfishing is based around trout and salmon the best time of year is also the coldest. In some cases anglers have to use anti-freeze on the guides to stop the ice from cutting their lines. No one said anglers were sane. You can buy gloves made of many types of materials, from neoprene to wool to cotton. Extreme winter to extreme summer.
The gloves especially are designed for comfort, safety and fine fingertip work, a good example would be these -

I do like a lot of flyfishing gear, and I am finding that for trips where I have to walk a lot I tend to grab a fishing vest and stick everything I need in it. Its close to my body and everything is at hand. I have balance issues due to a long term knee injury and anything that moves or swings has the potential to make me go splat so I tend to look at how I carry things and where I carry them. Flyfishing tends to be a lot of scrambling around rocks and boulders while carrying all your equipment, so a lot of this gear has been designed by people who wear it and not someone isolated from the consumers.
