Striker Elements Index softshell jackets are the ticket for most spring and fall mild temperature conditions or even in the rain. The Index Jacket has a very comfortable four-way stretch shell which is both water resistant and wind proof. This jacket is designed with our exclusive "drop tail back" for added coverage while sitting or bending over. Our sizing for this style is generous with longer than average body length and arm length. The versatile Index Jacket has a handy exterior cell phone pocket with zipper and two hand pockets with zippers. Warmth Rated at 2, which is about 40-50 degrees. The Index Jacket has fleece-lined arms too, so it is comfortable over a T-shirt.
