While the Exped Stuff Pillow performed reasonably well on a recent ski trip, I was disappointed that I could not fit a down jacket inside the pillow due to the internal chambers being very small. I had to find smaller items such as socks, hat and spare base layer items to stuff inside the pockets. I could fit a portion of my down jacket into the large pocket, but to put the entire jacket into the pillow was not possible. I do like the cut of the pillow and the way it fit into the head space of my mummy bag, but all-in-all I feel I am just as well off to use a stuff sack with my down jacket for a pillow or to go back to the old tried and true method of stuffing my down jacket into the hood of my bag. I was hoping this pillow would be as nice and user friendly as the Sierra Designs Sleep E-Z Pillow, but in comparison, the Exped Stuff Pillow fell a little short.
