Used a stuff sack for years until I started wearing layers to sleep in. Tried the exped ultralight pillow but it was super slippery. Some dabs of silicone cured that and it is secure and super comfy. When it's warm it goes between the bag and pad, and when cold it goes under the pad. Way better than a stuff sack ever was.
Where do you apply silicone? Right on pillow then put your head on it?
I have been using the Zpacks version of that for a couple years. The only difference is mine is a roll top.I just picked up a new pillow so I thought I'd go ahead and resurrect this thread. The Hyperlite Mountain Gear large cuben fiber stuff sack pillow is oh so sweet. I haven't tried it in the field yet but went ahead and stuffed my lightweight down jacket into it and it is super comfy and only weighs 1.5 ounces. Cuben fiber with a, probably not waterproof but very water resistant zipper, then turn it inside out and it has micro fleece on one side. I have no doubt that it just made my other pillows obsolete.
