Alpha RoS Light Limited Edition Jacket - Women's by Castelli
In an industry full of acronyms, Castelli adds to it with its Alpha RoS Light Limited Edition Jacket where the RoS stands for Rain or Shine, meaning this jacket offers both wind and water protection in formidable weather and also breathes well enough and manages moisture when conditions are more favorable too. Castelli does a wonderful job of calling out the temperature ranges for its kit and this jacket is well suited to its suggested temperature range of 46 - 59 degrees Fahrenheit.

Skiers and alpinists use Windstopper indiscriminately: their goal is to stay warm and dry at all costs. Cyclists' needs, on the other hand, change over the course of a ride depending on intensity, climbing, des...

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
