You packed sunscreen. You packed a snack. You packed a tiny first aid kit you have never once opened. You packed all of these things for a four hour hike because you are a prepared person and prepared people pack for the thing that might happen, not just the thing that will happen.
 
And yet.
 
The Day Hiker Bidet weighs 4 grams. It is smaller than your thumb. It fits in any pocket including the decorative ones on women's pants, and if those don't work it fits in your sock. It adds nothing to your pack weight in any meaningful way and it asks nothing of you except to be there on the one day in however many day hikes it takes before nature decides your schedule is not her problem.
That day comes for everyone. Ask any seasoned day hiker. They will not make eye contact but they will nod.
 
Four grams. Smaller than your thumb. Lighter than the granola bar you're already bringing. There is no version of this decision where you regret packing it.
 
There is absolutely a version where you regret not packing it. You never know when you gotta go.
