100% OPPOSITE of Partisan 1911 on Rivers West. i absolutely LOVE mine and would not trade it for anything. Very pleased and will continue to buy more. Ive worn it in terential down pours, to drizzle, to snow and "forced marches" thru soaked blackberry patches, to desert thunderstorms. Never had an issue with leakage. And its quiet.
I finally broke my main zipper on my 6 year old jacket and its on a discontinued model, so I wouldnt expect that they would fix/replace that one. But 6 years of Deer, Elk and Bear seasons, plus that many Duck and Goose seasons wearing every evening and weekend, mud, muck, and grime.... Thats some serious abuse.
Both my Rivers west jackets have zippers under the arms tho and when used for ventilation you stay cooler and dont sweat too bad, & thus stay dry. If your hiking steep ground in a downpour your gonna sweat and stay wet one way or another, from rain if zippers are opened, or sweat if closed, but it beats anything Ive ever had in foul weather gear by miles.
However I will agree with Partisan 1911 on the issue of anything breathable will not be completely waterproof.
I have never tried sitka gear, but I here decent feedback.
EDIT>>>> Just proof read, and my post seemed a bit coarse; I should point out that I have nothing but respect for Partisan 1911, and his opinions. Weve aggreed on many things in the past, and shared a few P.M.'s. We just have differing opinions on this particular subject is all. I meant nothing negitave.
