From OP: "What are your thoughts? How do you handle the very wet climates? Does the non-Goretex argument still hold? Or do those of you in wet climates end up using the Goretex?"
As usual, will dissent from the majority. A lot depends on whether you are talking wet/cold, wet/medium, or wet/warm.
For wet/cold, heed the majority. They have the experience that I don't.
For wet/medium – most of CONUS in Jun to Sep – I've been able to keep dry in extended rains in the NE and lately, CO (climate change), lasting 2-3 days, as follows:
1. Use the best Patagonia WB tops – have worked much better than GTX – Specter (1st
ed) and M10.
2. Treat mid boots well for leather and DWR (especially on the fabric surfaces)
Even worked on cheaper boots like Keen; but switched to Salomon – more durable
3. Wear heavier synthetic sox like Lorpen trekkers – durable, Coolmax, dry much
faster than wool, still feel dry if damp
4. Wear any good WPB shorty gaiter, incl GTX, over the boots/sox to keep water out.
5. Wear only Patagonia Baggies & mesh briefs. If legs get cold, add some fleece
underneath up top. Have tried softshell bottoms, but they eventually wet out.
6. Wear a WPB med. brim bucket cap – over a kerchief if too warm. In a deluge, the
cap stays on under the hood, keeping water off the eyeglasses, compass, map etc.
7. Don't overheat and overwhelm the WPB. Also, Speed + Slick = Injury
8. Use a shelter with a good awning(s) that pitches dry in the rain. A dry place to
recoupe, cook, eat, stash wet stuff etc., provides an environment to stay dry
9. Avoid totally immersing the boots at all costs – Carry SUL fording shoes.
10. Carry spikes if any chance of snowfields
There are probably more, but those come to mind. Probably wouldn't work in parts of the NW US that are close to rain forest weather. Daryl posted about the dryer weather in eastern Washington State. But has worked on combo kayak/BP trips where first week or two were on the water and it rained hard & incessantly. An extra tarp made life bearable. Wore plastic baggies over the sox under the sneakers to keep feet from freezing. Top stayed dry, but skin on feet got so saturated that couldn't hike for 3 days without it sloughing off. Was so glad to get back on the trail, even in the rain.
