The perfect fleece - keeps me warm on chilly days, without ever being too hot - as it breathes pretty well... I use the heavier Spyder jacket when the temps get below 35, and I can use either with my Spyder shell for skiing... Awesome jacket!Fits great, looks great, quality material, and best of all, it keeps you real warm in extermly cold weather. I ordered size small and it is slightly lose so you can wear something else underneath if you want.loved the spyder fleece sweatshirt, and my son appreciated the warmth and design during his winter ski vacation. but after only 1 week, the zipper broke in 2 places, in 2 separate ways! have written to spyder with a photo of the damage and am awaiting a response. given the price, this was very disappointing.Loved the idea of Spyder sweaters! Bought the heavy weight sweater in a Large and it is really big! Ordered the XL this model and it's way too small! Sent backRuns a little larger than normal. I'm 6ft 195lbs and usually wear a Large but Medium fits perfectlyGreat fabric and tailored fit. Looks great onThanks a lot perfect fit.Nice looking and feels very comfortableWarm and comfortable in all skiing conditions
