You still need to wear your personal camouflage and make sure all items in the blind are camouflaged as well. This includes coolers, blind bags, gun cases and other gear. Often well-camouflaged hunters will sit brightly colored shotshell boxes out in the open, forgetting that ducks can see them and may flare.

I think a facemask and gloves are very helpful. In particular, the camo mask allows you to look up and keep track of circling birds. I use two types of masks. For early season or mild weather shooting I use mesh masks and gloves. In cold weather, I wear a warm full-coverage facemask and insulated camo gloves.
