The polyester outer shell sports a relatively thick feel and adds abrasion-resistant ballistic nylon in the usual spots, with Reissa membrane bonded inside. Reissa is one of those “breathable moisture barriers” found on plenty of moto-apparel these days. On the Tempest, the outer shell and Reissa combo keep the rain at bay. There’s no inner liner, which is fine by me—I always lose those things anyway. On my frequent forays over the rainy roads of the Pacific Northwest, the Tempest has been surprisingly up to the task of keeping me dry, even with all those zippers. Helping the cause is a large storm flap inside the front zipper, which keeps a good chunk of the Reissa behind it to further help shut out the wet and cold. I also found the insulating liner to be nice and toasty, with sleeves that go to about mid-forearm.
