Christian Berg: Stuck In The Rut

Scent-Lok Claims Victory in Long-Running Court Battle

by Christian Berg   |  September 26th, 2012 9

After five years of legal wrangling, Scent-Lok announced this week that it has claimed victory and won a dismissal of all lawsuits challenging the effectiveness of its activated carbon scent-elimination clothing. The Scent-Lok news release and a link to the final court document can be found below.

On a personal note, I’d just like to say that I am always amazed when I run into a fellow hunter who swears activated carbon doesn’t work, because clearly it does. Now, I am not saying that using activated carbon clothing — or any scent-elimination technology, for that matter — completely eliminates 100 percent of your human odor. But I am saying that anyone who thinks activated carbon doesn’t adsorb odors has obviously never used it. Actually, you can do some pretty simple experiments at home using activated carbon powder that can be dissolved in water. Just take a smelly piece of clothing, soak it in the water with activated carbon and hang it out to dry. I guarantee it will smell like nothing when it’s dry. I use this method to take the “new” smell out of items such as safety harnesses and other gear.

The activated carbon used in Scent-Lok clothing operates on the same principle, only the carbon is bonded to the fabric in the clothing. As the company notes in the press release and court document, the legal process produced a variety of information offering examples of activated carbon’s effectiveness at eliminating odor, which is why it has been used for decades in numerous odor-control efforts across a number of industries.

As a disclaimer, I am not promoting Scent-Lok or any other company’s products. I am just pointing out, as an experienced big-game hunter, that activated carbon is one of a number of effective scent-elimination technologies available to us. I can tell you from personal experience that the more you can control your scent, the better, and while I am not sure any technology is a magic bullet, I do believe hunters who pay attention to personal hygiene and take advantage of a combination of scent-control products available to them can significantly improve their odds of getting within bow range of critters in the field.

Here’s the Scent-Lok news release:


ALS Enterprises, Inc., the maker of Scent-Lok® odor reducing carbon hunting apparel, has obtained a complete victory in the nine federal lawsuits that challenged Scent-Lok®’s ability to control human odor. After over five years of litigation, plaintiffs have agreed to take nothing and dismiss all of the pending lawsuits with prejudice. The final straw for plaintiffs was the district court’s August 17, 2012 Order dismissing the first-filed Minnesota case. In that Order, the district court noted the extent to which these lawsuits were lawyer-driven: “the Court is firmly convinced that ‘this litigation is so feeble that it is best to end it immediately,’ as its ‘only goal . . . appears to be fees for the plaintiffs’ lawyers.’ Indeed, it would simply ignore reality to believe that this case is about anything other than fees at this juncture, given the small number of Plaintiffs and the paltry damages they could recover if they were to prevail. There exists no perceptible public benefit.”

Less than a week later, plaintiffs agreed to end the eight other lawsuits as well. As explained in the final stipulation of dismissal, a copy of which is attached, Scent-Lok® products give hunters a real advantage:

• “Expert testing found that, using highly elevated test odor concentrations that were ‘likely a ten thousand fold greater than a human body could produce in the course of 24 hours,’ Scent-Lok® carbon hunting clothing fabrics blocked 96-99% of the odor compounds, and essentially 100% of the surrogate body odor compounds tested.”

• As exemplified by the test results below, Scent-Lok® carbon hunting clothing fabrics dramatically outperformed non-carbon fabrics at blocking odor permeation in head-to-head testing:

• “Expert testing also found that after drying, or washing and drying, Scent-Lok® carbon fabrics continue to be highly effective at blocking odor permeation.”

Greg Sesselmann, Scent-Lok®’s president and the inventor of carbon hunting clothing, commented: “We are gratified and vindicated by our win in these nine lawsuits. It gives me great satisfaction that Scent-Lok® products were shown without question to be highly effective at reducing odors, which allows hunters to get close to wildlife and experience the beauty of nature like never before. It saddens me to think that plaintiffs and their lawyers are allowed to use the legal system to bring groundless lawsuits against companies like ours.”

“Our customer satisfaction level is extremely high, based on survey evidence and unsolicited testimonials from hunters, because Scent-Lok® products work unbelievably well,” Sesselmann remarked. “Customers don’t need an attorney to get total satisfaction from Scent-Lok®; our products come with an unconditional satisfaction guarantee. On behalf of our consumers and retail partners, we remain focused on making products for the best hunting experience in the world.”

Scent-Lok Court Stipulation


  • Jack Coad

    never doubted the effectiveness of Scent Lok products regardless of what a court may rule. I make my decision based upon thousands of hours in a tree stand. Keep up the great work.

  • Dan Spoelman

    Congrats Greg and the Scent-Lok team, It is sad that a good american company has to go through what you did just because of some money hungry lawyers. The Scent-Lok products have alway been my number one choice for scent control.

  • Bob Morris

    This is crazy. Carbon can't pass one real scientific test . Even those who originally declared it worked to the Patent Office with drew their support (Myles Keller for one) . There are so many miconceptions and so many reasons why Scentlok and the others sealed all their testimony.(Their own carbon expert (Amos Turk )said under oath that it wasn't effective when questioned .Just ignor it ) The lab used has been shown to not to be one of the best and was paid to due the test and was not independent. If you want to hang your hat on this go ahead. Having developed the concept called " cold fusion" in 1997 with Freundenberg I can tell you that carbon sprayed with glue that fills the pores will not pass the smell test . Enjoy lining their pockets. They pay good money to by their support from the so called pro's and experts.

  • Christian Berg

    Bob, define doesn't work. As I said in my post, I use activated carbon power to de-scent new gear such as safety harnesses. It clearly removes the odor of new fabric, and that's something I can smell with my own nose.

    Also, as I noted, I do not think carbon is an end all, be all of odor elimination. But when you say flat out that it does not work, what EXACTLY do you mean? Because such a statement doesn't just make sense to me. Are you saying that activated carbon can't adsorb odors? And, if not, how do you explain what happens if I take something that stinks, expose it activated carbon and then find the stink it gone?

  • Christian Berg

    Bob, I meant activated carbon POWDER, not power. Sorry for the typo.

  • Bob Morris

    Properly understood carbon that is brand new will work . Once it is used it is no longer going to work. This process of enclosing carbon between to layers and using glue to(Adhesive) attach it to the fabric would fill the majority of the exposed pores. That carbon can be reactivated a low dryer temperatures is a myth that goes against all scientific data concerning carbon reactivation. All the rest of the carbon users have to use temperatures of 800C but not Scentlok and Scent Blocker . They use magical carbon that can be reactivated in a home dryer. Why not share their information with the rest of the world ?
    If anyone actually followed the trial closely it was about their advertising and not about whether the product actually worked. Just a casual reading of the transcripts shows that the product didn't pass the smell test according to experts on both sides. If Scentlok has nothing to fear why don't they release the sealed testimonies of thier witness. They don't dare. Especially the one given by Greg Sesselmann

    • Mike Andrews

      Bob, Contact me at Scent-lok and we will show any data that you want including the court documents that clearly show ScentLok can be reactivated and the appeals court ruling that deemed the term "reactivation" was NOT false. Bob, you need to understand a little more science, like physical adsorption vs. chemical adsorption.

    Doesn't really matter,Under Armour blew by you in the scent game!

  • Duffer

    I give it the chili test. I eat a bunch of chili and if I can smell the results it doesn't work. Scentlok never passed. Scent bloccker was much better but not complpetely. The best one yet was some off brand no scent outfit that passed for 2 yrs and 100s of hrs wearing it in the field. Half the price as the other two and worked so much better. I'm done paying for something that can't contain a fart. I'll stick with the Bill Winke suit (works great) and most importantly play the wind.
