Can we all agree that ultralight backpacking was a dumb fad, and we all fell for it? Let me critique some of the points illustrated by this infographic.

>breathable DWR bivy sack
Either use fully waterproof/breathable top or else use nothing and just choose an airy enough campsite. The DWR always wets out in moist conditions and it always sweats from the inside in humid conditions.

>lightweight quilt
Except it's not efficient at all to use a sleeping bag that lacks a hood and that lacks a zipper. The mummy bag is popular because it works.

>torso pad
Only makes any sense in the summer. Terrible idea in the fall, spring and winter, when you really need it. Your pack isn't comfortable and, especially if you take the ultralight meme to its extreme where you are using a totally fabric 5 ounce backpack, doesn't provide enough (or maybe any) insulation under your legs.

>bear spray
Terrible idea at night when you can't be sure of wind direction or when you might use it from inside your tent. Great way to suffer vision loss and uncontrollable sneezing/coughing. Just carry a gun.

>stuffsack for a pillow
The real question is what the hell do you have left over to put into it on cold nights, when you'll need to be wearing your jacket? It's a lot more comfortable to use an inflatable pillow. Exped makes a good one.

>sleeping on your back
Enjoy the sensation of choking in your sleep.
