That last steep climb to the summit ridge left you hot and sweaty, but you're going to get cold quick when you take a break amidst those howling upper elevation ridgeline winds. It's in times like these you'll be glad you brought the Columbia Men's Trask Mountain 650 Turbodown Hooded Jacket along on your hike. Insulated with a combination of down and synthetic fibers, the Trask Mountain offers exceptional warmth in a water resistant package. The durable 30 denier ripstop nylon will take some abuse and is water resistant, so it won't be game over for the down fill if the jacket happens to get a little wet. The attached hood is nice when you leave your beanie at home, and the drawcord adjustable hem seals in the heat when things get really cold.
