Why Lamilite Insulation?

The single most important component of any insulated product, be it a sleeping bag, parka, bib, snowsuit, booties or mittens, is the insulation inserted into these products. All insulated Wiggy's products have only one insulator: Lamilite.

Lamilite, which uses a continuous filament fiber called Climashield® by Harvest, CI, Inc. as its main component, is the best material developed thus far for use as insulation in sleeping bags or outerwear. I believe that our sleeping bags and extreme cold weather outerwear are so good that to purchase any other brand is a waste of money. To purchase a sleeping bag with any less quality could not only mean a very unpleasant camping trip, it could also mean your life. I say "your life" because I believe a sleeping bag is the most important piece of equipment you take into the field.

The functional difference that truly sets the Wiggy's Bag apart from the rest is its insulation! Lamilite possesses an extraordinary quality that helps contain the flow of heat that your own body generates. The key to Lamilite is its ability to allow the body's own thermostat to function efficiently.

Lamilite is Lofty Insulation

The more loft surrounding your body, the more difficult it is for your body heat to escape.

Lamilite is Lightweight

The lighter the weight of the insulation the lighter the weight of the finished product be it a sleeping bag or garment.

Lamilite is Very Soft

Put on a Lamilite parka and you will automatically think it is a down filled parka. The same holds true for our sleeping bags. They surround the body much the way a down bag does, filling in or draping closed around the body. This eliminates heat loss from convection. Conductive heat loss is reduced significantly. The fiber used for Lamilite is not densely packed into our products (as will be explained later) therefore, the loss of heat via conduction is minimized.

Lamilite is More Than the Fill Put Into Our Sleeping Bags

It is a combination of nylon fabric and fiberfill, two components that aid each other. The first part is visible. It is the 70-denier nylon commonly known as single ply taffeta. The 70 denier refers to the thickness of the yarn. The actual weave is 86 yarns in one direction and 104 yarns in the other, per square inch. The thickness of yarn is the optimum thickness to absorb body heat and quickly warm to your body temperature. The faster this warming occurs, the slower the rate of conductive heat loss from your body. The spaces between yarns in this construction allow the moisture your body produces to easily escape. It is irrelevant how dry a climate may be, your body gives off moisture. Therefore, it is important to allow this moisture easy exit. Water is extremely efficient at absorbing heat, so you always want to stay as dry as possible.
