There are several,mostly clothing related.Patagonia micro puff pullover,the lightest warmest compressible piece I have ever seen,smart wool or Ulfrotte long underwear,Enigma jacket and pants,unbelievable how soft the fabric becomes with washing,Danner Canadian boots,Icebreaker hand muff with acouple of handwarmers in it nothing will keep your hands warmer.
I still have an old Bushnell rangefinder that doesn't owe me a dime and has helped me immensely.I am sure there are others.
