Gore-Tex Stream
A great jacket for those looking to bike in cooler climes, the Stream has additional insulation to keep you warm. In addition to Gore-Tex's legendary combination of breathability and waterproofness, the Stream has a number of features suited to the biker, including longer sleeves and a deep cut to the back that keeps splashed water from soaking you. The Gore-Tex Stream can be found for around $139 (as of 2009).
Carradice Pro Route Rain Cape
While not commonly used in the United States, England has long since discovered the value of the rain cape when riding a bicycle. While it will greatly hamper your speed, nothing beats a cape for dryness and ventilation. With the Carradice Pro Route, your arms attach inside the cape and a waist belt is cinched on to provide a broad, pyramidal covering that is guaranteed to keep your entire body dry. The Carradice Pro Route can be found for between $65 and $80 (as of 2009).
Novara Express
Exceptional bicycle rain pants, Novara Express offers coverage of the lower body for riders interested in a full rain suit. Easily slipped on and off, the Express can be thrown on quickly when needed. With taped seams and a tightening cuff, the Express can be made as snug and as waterproof as is necessary. Plus, REI offers the Novara Express rain pants for only $46.50 (as of 2009).
Cloudveil Switchback
An excellent alternative for those looking for something a little more versatile than a raincoat, the Cloudveil Switchback is representative of soft-shell cycling jackets. These jackets aren't waterproof but are sleek wind-blockers and general-use shells. They'll keep you dry for short bursts. Most important, the Cloudveil Switchback breathes well and may keep you drier than a standard raincoat if you tend to sweat a lot. One downside to the Cloudveil Switchback is the price, which at around $200 (as of 2009) can be a bit taxing on the wallet.
