Not in my opinion and I have two sets that I haven't used in 2 or 3 years. It's hot, doesn't breath well and contrary to what they preach it can NOT be regenerated in a home dryer. Sweat and fatty acids from the body are a non volitile substances, meaning, they do not vaporize out of the clothes as advertised. This "Replicated Human Odor" they talk about in their advertising is a volitile substance that can be collected to an extent by carbon and released with heat because it does vaporize. It's not the sweat and fatty acids of the human body. I refuse to buy boots and clothes with scent lok or scent block in them. Why should I pay an extra $40 or $50 for something I don't want and it doesn't work. Boots are especially ridiculous. You can buy two sets of regular camo for the price of one scent lok.... that's the direction I'd go. If you're in snow country one of those should be a snowflage or something like Skylines Horizon for hunting in the snow.
