The 686 Smarty Gore Tex jacket is the first in the 686 line to use Gore-Tex waterproof membrane which makes it one of the most waterproof jackets on the market. There are removable SMARTY liners which makes this jacket suitable for both colder days on the mountain and warmer days as you can simply zip out the insulation when you don’t need it. The trousers also have removable insulation. If you want to get one set of gear and not need to mess about with insulating layers this set will sort you out in any conditions.
