I have the H7 bids and jacket H5 (I think) and am very happy with them. They are like anything else though, you really need to learn how to use them with your style to hunting to get the most out of them. Everyone responses to the cold in different ways also, so you have to consider how you handle the cold as well. I typically only wear a pair of poly thermals and shorts under them. I will wear this until I get close to my stand them change my shirt and dry myself off. After if have cooled down for minute and am dry I put on what I am going to wear as base and mid layer on top and put my bibs on and go on to my tree being carefull not to sweat up. You can use different layer underneath to depending on you you respond to cold. I will sometime add heat packs to my kidney area and between my shoulder blades if it is very cold add a little more heat because your body produces less heat blood flow slows down. I was someone who was alway cold, especially my feet, but sense is learned how to layer properly for the clothes I don't get cold like I used to. Alot of times now, I don't even wear insulated boots because my core temp is staying high enough that my feet stays warm.
Arctic Shield is not a miracle clothing, you have to use it correctly to get the most out of it. But, In my opinion, if you use it correctly it is well worth the money.
