If you're going to save the world (AGAIN), you'll need a few things first. Power. Wisdom. Courage. And you should probably pack some water, sunscreen, and layers so that you'll be protected regardless of the environment.
Hey - this Legend of Zelda Triforce Pull-Over Hoodie looks like a good option. It's medium-weight. It has a hood to protect you from some of the rain in Breath of the Wild. But we wouldn't suggest it as climbing gear unless we're talking about climbing into the back of an SUV or climbing up on the couch for a long day of gaming.
