The sweater was a little lighter than I expected, but honestly it's still super comfortable and I've been reaching for it a lot. Overall, I'm happy I bought it.

The jacket arrived quickly and honestly looks even better in person. The fabric feels high quality, and it's warm without being bulky. Pleasantly surprised.

I had a small question about sizing and their customer service got back to me the same evening. They were super helpful, and the size they recommended fits perfectly. That gave me confidence to order again.
