Not a bad little guy
Like almost any piece of essential gear, this guy is costly. I could hardly justify $80 for a tarp/poncho but in the end it proved it's worth. Got caught out on the trail at about 9000ft when a freak storm rolled in and dumped hail and rain on a less experienced (and less prepared) friend. He was soaking wet and cold. Me, bone dry and toasty. I quickly pulled off the poncho strung up some rope and a trekking pole and viola! Quick shelter for my friend to get warm, change into dry clothes and wait out the storm. Still, you could probably make you own (albeit heavier) for far less than $80.
