The Climbing Gear set in Zelda: Breath of the Wild consists of three pieces: the Climber's Bandana, the Climbing Gear, and the Climbing Boots. Here's how to find the Climbing Gear in BOTW and what you need to upgrade the entire set.
Locations of the full climbing gear in Zelda: Breath of the Wild
The climbing gear in Breath of the Wild can be found in treasure chests in the following shrines:
The Ree Dahee Shrine is located on the river that runs through Dueling Peaks. From Dueling Peaks Tower, glide east and land on the northern mountain, then descend. Solve the puzzle in the shrine and collect the Climber's Bandana as a reward.
Chaas Qeta Shrine is located on a small island southeast of the mainland in Hateno. Climb up onto the Hateno Ancient Tech Lab and glide down to the island. Once inside, you’ll need to defeat a Guardian Scout IV if you want to walk out with the Climbing Gear, so go in prepared for a tough fight.
