This will TOTALLY depend on which trip you come out on. The clothing you want for the northern lights tour and the clothing you want for the coastal brown bears tour are 2 entirely beasts. Clothing for Winter Photography.
As a basic standard though, you want to be warm, dry and comfortable. For the Grizzlies in the Fall Photo Tour, you definitely want a pair of chest waders.
If you are interested in a particular trip give me a call or drop me an email and I’ll be glad to forward you with some more information specific to the trip you’re considering.
Like your camera gear, this subject is largely contextual. You want to be comfortable and don’t skimp on your gear.
Practice with your camera equipment before heading out on a trip. You don’t want to fly thousands of miles and spend thousands of dollars for that one chance to shoot a grizzly flying through the water and miss it because you weren’t sure how to adjust your camera/tripod/waders/shoelaces/etc. 🙂
