Live and work outdoors on the west coast. It amazes me how many 100% waterproof advertised products fail miserably around here. Have tried lots of rain wear.
Outings where not worried about sweating Helly Hansen impertech. All day hikes arcteryx leaf alpha, brutally exspensive, but in remote areas where staying warm and dry could be a life saver, worth every penny. These are my choices for week long downpours where it just doesn't let up and your in rain gear all day. We get the most rainfall in North America around here and unfortunately a lot of manufacturers/internet claims have cost me a quite a few bucks
