Frequently Asked Questions
How long has Shiver Shield been available?
 The development of Shiver Shield is just now being completed. The insulation in Shiver Shield has never been available on a commercial basis for use in clothing. In fact Shiver Shield is assisting the insulation manufacturer in development of the process to bring this technology to market as soon as possible. Shiver Shield will be available in the very near future.
What makes Shiver Shield so warm?
 Shiver Shield uses a revolutionary insulation called Zero-LoftTM, which has never been available for use in clothing on a commercial basis before.
Why should I buy Shiver Shield versus other insulated clothing?
 When you consider the heat retention properties of insulation, Zero-LoftTM is absolutely the warmest insulation per unit thickness that is available for commercial use in clothing with no exceptions. Most people are familiar with the fiberglass insulation used in your house. For comparison purposes, Zero-LoftTM is nearly 40 times more insulative than fiberglass insulation.
Just how warm is Shiver Shield?
 Well, the best way to answer this would be to compare it to something common. Zero-LoftTM is two to EIGHT times warmer than the most common loft insulations used! It provides 39 times more insulating capacity than the best fiberglass insulation! There's absolutely no comparison.
What or who was Shiver Shield developed for?
 Shiver Shield was developed for people that are going to be exposed to extremely cold environments for long periods of time, especially those that will have minimal activity.
Who should consider purchasing Shiver Shield?
 Shiver Shield is ideal for anyone involved in activities such as bow hunting in late winter, ice fisherman, snowmobilers, working in a cold storages or freezers, working outside in careers such as security, toll booths, late season sports fans or any other activities that will take you outdoors when low temperatures are inevitable. If you are one of those people that always gets cold and has to go inside to get warm before you want to, then Shiver Shield is your answer.
How is Shiver Shield constructed?
 Shiver Shield has three thin layers. The inner layer is a moisture wicking micro fleece that is extremely soft and comfortable against your skin. An extremely thin middle layer of Zero-LoftTM insulation, and a fashionable outer shell.
Is there anything that I should be cautious about with Shiver Shield?
 Due to the unique and revolutionary insulation and manufacturing techniques required, Shiver Shield can NOT be sewn, punctured, or in any way ruptured. Caution should be taken to avoid getting holes in your Shiver Shield clothing. This could significantly reduce its insulative capability
Shiver Shield seems to good to be true and I have been told my entire life that is if it seems to good to be true, then it probably is. Is this just another one of those product gimmicks that has a new name that is really no different from the other products I already have?
 Shiver Shield is uniquely different than any other garment available. You have NEVER had the opportunity to purchase a cold weather garment with Zero-LoftTM insulation technology in it. You simply must try it to believe it for yourself to see how something this thin can be this warm. In fact don’t be surprised if you get too hot!
How do I use Shiver Shield or is there any special instructions?
 Shiver Shield was designed to be worn as an under garment when concealment is required such as in deer hunting or as a casual outfit for everyday uses.
Should I expect any differences between Shiver Shield and my old heavy and bulky insulated clothing?
 Due to the extremely thin layers of Zero-Loft, Shiver Shield will allow you to have more mobility and less constriction than the standard heavy and bulky clothing made from loft insulations.
Who developed Shiver Shield?
 Brian McFarlane was the developer and founder of Shiver Shield. He has been an avid outdoorsman and bow hunter for nearly 30 years. Growing up in Michigan and then raising his family in Nebraska, he has been able to experience extremely cold winters and many cold hours in the outdoors. He was never happy with the bulky, heavy, and not so warm “top of the line” clothing that wouldn’t allow him to enjoying his passion for the outdoors for extended hours during these cold fall and winter months. He has been looking for a solution for many years. Shiver Shield was the answer to his uncontrollable shivering.
What is the difference between a loft and non-loft insulation?
 Most clothing insulation is commonly referred to as “loft” insulation. Loft insulations are fibrous materials that insulate by entrapping air between the fibers. It is this entrapped air that the insulation heavily relies on for its insulative properties. It is also critical to maintain its "loft" to maintain its insulative properties. For example, you can't simply stuff two layers of insulation in the walls of your house and expect it to be twice as warm, because you have compressed the insulation and signficantly reduced in insulative capabilities. A non-loft insulation does not have this empty air space in its structure and thus has better heat retention and thermal properties even under compression.
What is different with Zero-Loft and other insulations that I am used to wearing?
 Zero-Loft is extremely different. It is made with a revolutionary nano-technology that produces a material that is over 99% air, but the air is encapsulated in the material in such a way that it cannot escape. In other words, it doesn't need the bulky air pockets to insulate. That is why Zero-LoftTM retains its insulative properties under pressure or compression (example - when you are setting on that cold tree stand or aluminum bench at your kids football game).
How can something so thin be so warm?
 Because of the nano-encapsulation process that entraps air into the structure of Zero-Loft, this allows very thin layers of Zero-Loft to prevent heat transfer.
How can this insulation be so warm and waterproof, yet moisture permeable?
 The materials used to manufacture Zero-Loft insulation are “hydrophobic” which means they don’t like water. This give Zero-Loft the inherent ability to repel water. But because of how it is constructed, it allows moisture vapor to transfer through the material.
Can I wash and dry Shiver Shield with normal procedures in my washer and dryer at home?
 Due to the extreme variation in residential washers and driers we are recommending that Shiver Shield be dry cleaned.
Does Shiver Shield have any scent prevention or elimination properties?
 We have decided to not incorporate any type of antimicrobial into the fabrics used in Shiver Shield. We are still investigating to find an antimicrobial fabric that meets our high standards. However, we are nearing completion of a line of heat and moisture activated odor control products named TKO. These were specifically designed to be used with Shiver Shield. With the extreme warmth of Shiver Shield, it is important to have an odor protection that works extremely well while the body is generating heat and possible sweat. TKO is designed to be used on the inner layer of your hunting clothing and as you heat up, TKo activates to control odors from building up. TKO can also be used on all your clothing and equipment to help prevent being detected by prey. TKO in combination with good personal hygiene is best method for scent control and elimination.
Can I wear my other clothing with Shiver Shield?
 Absolutely. Although you don’t need to, Shiver Shield is ideal to wear with compression clothing such as Under Armour, under your scent control garments such as Scent-lok, or any other special clothing that you like to wear for your desired application or need. Shiver Shield will only improve your experience while wearing these other products.
What sizes is Shiver Shield available in?
 Shiver Shield is going to be available in men’s small through 2XL. We are currently working on women’s and youth sizes.
