The Marmot Crystalline skyrocketed into the spotlight. It gives the Outdoor Research Helium II a run for its money--keeping up in waterproofness and breathability, as any good rain jacket should. Overall, it couldn't beat the Helium II for our Top Pick for rain protection award, but not by dint of any major flaws. Instead, OR proved itself with better focus on the purpose of the jacket: as an ultralight, simple, athletic rain jacket. No frills, fewer pockets. The Crystalline had a few extras that detracted from its purpose. Still a great jacket.
Outerwear is designed for function first, but style is often a close second. The Marmot Crystalline emerges as a winner in the style department with a bold use of white in a rain jacket. The light color is translucent and elegant and melds the color you're wearing underneath into the jacket. We were surprised at first by this choice but quickly grew to like the crisp, crystalline look it lends to your outfit.
