"Excellent jacket for low intensity or city wear."
This is the best in-city rain jacket I've ever owned. No pit zips, so probably not your best bet for high-intensity activity, but it's completely waterproof and has a great athletic fit. My only reservation is that the hood is a bit big (to accommodate a helmet, I suppose, but this isn't the kind of jacket you'd wear to ski or climb).
The Beta SL has been my backpacking rain jacket of choice for the last three years. I have put this thing through hell and it has never been phased. It has withstood hours of downpours in canyons, allowing for longer days of fishing. Now, it is by no means a rival for the Beta AR or Alpha LT, but for being a Paclite jacket I couldn't be more impressed. This being said, I wish it had pitzips. The Paclite fabric breathes pretty damn well, but as far as air circulation goes, nothing beats some zips.
