diane rwrote a review of Castelli Ispirazione Women's Jacket on February 13, 2013
This jacket is VERY warm. If it's above 50 degrees you are going to get hot real fast. Below 47 is better. It is windproof and has a thick fleece like lining. The jacket is form fit, so you won't be able to layer up much under it, but you won't need to. I can only get a base layer under it as the sleeves are fairly snug. I ordered this Jacket for the coldest winter days and it's exactly what I needed. So glad I have it. I love the look of this Jacket. I'm 5'2", 120 lbs. A size small is a perfect fit!
Note: if you are a casual rider, you may not heat up as much and be able to wear it in the 50 degree range.
Yesterday the temp was 43 wind chill was 33. I had this jacket and a base layer and I was perfectly warm the whole ride. Very happy.
