I think it has a lot to do with perceived value too. For my 1/2 to 3/4 mile walks in to hunt, 8oz doesn't mean very much. If I was hiking 10-15 miles it suddenly becomes a bit more important to me.One of my other hobbies is ultralight backpacking. Dudes in that world don’t think twice about spending a few hundred to save 8 OUNCES.
Funny how it’s all relative.
