I'm not sure how to say this exactly, but this jacket negates weather. If it is 40 degrees out and sunny, it feels 40 degrees. If it is blowing and raining out, it feels 40 degrees. I skied with just this jacket and a T-shirt on a warmish day and it was perfect. It adjusts very well to any weather. It isn't a warm jacket, but it is a perfect shell. If you cinch it up, wind won't penetrate the sleeves or the waist. It is thin enough to wear under a heavier jacket if it gets very cold. I've taken to bringing this jacket with me where ever I go because its so versatile. I've worn this for 6 months, and you'll never regret buying this jacket.
The jacket seems great, but I immediately returned it due to the material the pockets were made out of. Its a synthetic mesh that catches on skin and is quite uncomfortable to bare hands. This is probably a personal pet peeve, but none the less, it was a deal breaker for me.
Purchased to have another option besides a heavy jacket on the not so cold winter/spring/fall days in the Midwest. I love the fit, finish and the way that wind is no problem with this jacket. It looks great with jeans or khakis. Description says best with lightweight layer, but I can still wear my jacket (size small) comfortably with a hoodie underneath on the below freezing days. Fleece cuffs are a nice feature as well.
Have purchased other LL Bean products over the years and this is another great addition like all the rest. Certainly would recommend it.
