Vince,

I've got a Simms that I think was second from their top line product. It's Gortex, and it works well for me under a range of conditions. Like many, I'm turned off by the pricing, so I bought it as "last year's model" for half price. Not a viable alternative if you need something this week.

The more you sweat, the more you need the most breathable fabric, and from what I've heard, that still means Gortex instead of one of the other breathable fabrics.

Sincerely,

Salmo g.
