Tech does have a good point, so Link nods, and puts the armor away. The entire armor. First the helmet, then the top half, then the bottom. The whole lot of it just disappears entirely.

He hasn't let go of the Lightsale Trident just yet, though.

Then he walks back out of the aisle - looking for the last thing he has here. For this one, though, he has absolutely no idea what it will be.
