The System - The right underlayer for the conditions combined with Sleeping
Indian wool means "Comfort"

THE SYSTEM - What
makes the Sleeping Indian Designs system work? How can you comfortabally have a 100 degree
temperature range? The answer is in the right clothing and effective layering. Review the
above picture and what you see is Effective Layering.
Layer One = Moisture regulation the key element
(cotton, silk, synthetic or blend)
In high temperatures, slowing the rate of evaporation next to the skin maximizes cooling. Cotton underwear does this best by holding moisture. Just the same, in colder temps, cotton underwear should be avoided when moisture needs to be wicked away from the body to stay warm.
In moderate temperatures, your level of exertion will determine whether faster or slower evaporation will be optimum. Light or medium weight silk or poly underwear is recommended.
In coldest temperatures, fast wicking is essential to comfort and safety. Heavy weight synthetic underwear is ideal.
Layer Two = Insulation (shirt, pants, hat)
In higher temps 45 thru 60 degrees. In this range I find the Sheep Mt or Mt Range Shirt and Pants ideal for early spring and fall scouting or hunts.
Layer Three = Extended Insulation with Windblock (lined vest, hat)
In moderate temps 30 thru 45 degrees. In this range I like the Highline or Ridgeline Shirt, Sheep Mt or Mt Range Pants and Sheep Mt or Mt Range Vest. (In Michigan Bowhunts 80-90% of the season is spent in this clothing combination with the right underlayer based on weather conditions)
Layer Four = Extended Insulation with Windblock ( vest, coat, anorak, gaitors)
In coldest temps -40 thru 30 degrees. Time to pull out the Snowline Vest, Timberline Pant, Grand Teton Jacket, Wind River Parka or Archers Anorak. Depending on the weather your choice for this layer of clothing will guarantee comfort.
Why Sleeping Indian Designs? - Wool is the origional wicking fiber. Each hollow strand is naturally engineered to trap heat while resisting moisture buildup. Each follicle of wool contains both hydrophobic (water hating) exterior shaft and a hydrophillic (water loving) inner core. This gives wool the unique property of wicking perspiration away from your body, while at the same time shedding outside rain or show. As an insulator, wool will maintain 60% of your body heat when wet, a potentially life preserving feature in severe weather conditions. Combine the qualities of wool with the correct underlayer and you get the absolute best in outdoor comfort over the widest range of temperature. No manmade fiber can offer you the same.
