My current favorite method is to find a safe stretch on the ride, look way up, pour a ton through the helmet at the mid-back point, and keep looking up for ten seconds. The excess will then flow on to the back. Too much and it will get all the way to the pockets and too little will wet too little so it takes some practice to get right. There is no water wasted this way. If you don’t look up long enough some excess will drip down in front and get wasted.

I also will spray a small amount on front and shoulders but there is more waste so I don’t use too much there. Of course if a refill station is coming soon, let ‘er rip!
