Yes I always keep it sealed up. But Im in and out of it all the time during season.(I got 4)I also change the neddles and branches about every 2 weeks so the scent is strong. I kind of grind them up a bit put them on the bottom.Put some chesse like cloth over that then my stuff on top.I also keep a pair of gloves just for climbing with to keep the sap off my hands(ever try to draw with sticky hands-not good)and hang the gloves buy mein stand because they smell like pine big time.
