It's tough to think of a chilly-weather situation that a North Face Triclamate Jacket couldn't handle. The North Face Blaze Triclimate Jacket, in one form or another, is totally prepared for everything from zero degrees and sunny to fifty degrees and pouring rain, and everything in-between. The shell jacket handles precipitation with waterproof, highly breathable FlashDry protection, while the liner jacket locks in heat with synthetic FlashDry insulation.
