PrimaLoft is a synthetic down alternative that is a popular fill used by a number of different companies for products like bedding comforters, jackets, gloves, sleeping bags, footwear, and other outdoor products. Among synthetic materials, it is considered to be a luxury down alternative because of its superior characteristics over other imitation synthetic downs.

This material was actually developed under contract by the US Army in 1983. They used real goose down feathers in things like clothing and sleeping bags that were manufactured for the Army, but there were a number of problems experienced using real down.

For the military, one of the most crucial problems is the fact that down loses its thermal insulation properties when it becomes wet. Obviously, soldiers are bound to get wet at some point, so they needed something that was water resistant and would still retain heat when wet.

By May 1986, PrimaLoft One had obtained a patent for its synthetic down. By 1989, this material was put into commercial production for use in jackets sold by L.L. Bean. Since that time, it has been used in a variety of other outdoor apparel and even bedding products to replace traditional down feathers.

This synthetic down has a number of advantages over real down:

  • Thermal Insulation – When dry, both materials perform equally, but when wet, the real down loses structure and no longer holds air to retain heat. The synthetic material maintains loft even under wet conditions.
  • Hypoallergenic – A lot of people that have allergy sensitivities have reported issues with real down feather bedding products, but synthetic down does not experience this issue.
  • Machine Washable – Since real feathers lose insulation properties when they get wet, they cannot be washed at home in a washing machine (they need to be dry cleaned). However, PrimaLoft based products can be safely washed in cold water on the gentle cycle and even tumble dried at a low temperature.

Amazon’s exclusive brand, Pinzon, utilizes this material in their hypoallergenic down alternative comforter. It also features Ribbon Fiber Technology that allows it to be compressed and then quickly regain its loft.

For anyone interested in a PrimaLoft comforter, we recommend Pinzon’s for their quality and extreme affordability. For a luxury down alternative comforter, it is really difficult to find another one of this quality for the same price.

How does Amazon do it? Their secret is not having a brick-and-mortar retail store. This gives them lower operational costs than the competitors and they pass along the savings to you.

The Pinzon PrimaLoft comforter is manufactured by a company named DownLite that makes most of the PrimaLoft line of bedding goods. This is not just for Amazon though – we’re talking about other major brands like Bed Bath & Beyond, Sealy, Macy’s, Eddie Bauer, Bloomingdales and many more. They have also manufactured these products for every single major hotel chain and many cruise ship companies and private properties.

If you’ve ever gone on a vacation to a nice hotel and had a wonderful night sleep on a very comfortable bedding set, you most likely slept on PrimaLoft products. You can now get that same comfort in your own home for a price that will shock you because it is so affordable.

Product Summary: Enjoy a great night's sleep with a Pinzon comforter just right for your needs. For sensitive sleepers who want to enjoy the benefits of down, the Pyrenees PrimaLoft comforter offers exactly that. The comforter is made with a patented filling that is the closest thing to down available in a synthetic fiber. It's called PrimaLoft, The Luxury Down Alternative, and it has many of down's amazing properties, like lightness, warmth, and loft. But PrimaLoft provides fabulous qualities that down doesn't, such as water-repellence, which allows it to dry faster and use less energy. This full/queen comforter is filled with 50 total ounces of PrimaLoft to offer medium warmth for year-round comfort. Though overall it feels lightweight and supple, the comforter provides immediacy of warmth and quickly passes body heat and moisture vapor to the surface for sleep that is comfortable, not hot or heavy. As a gauge for filling quality, the Pyrenees PrimaLoft comforter has a fill power comparable to what would be 550 in a down comforter. Fill power indicates how many cubic inches of space an ounce of down will occupy, and the higher the fill power, the better the quality. Everything at 500 level and above is high quality.

The Pyrenees PrimaLoft comforter is made with a sewn-through box design from end to end. In this construction, the bottom of the shell is laid out, the filling is placed over it, the top of the shell covers the filling, and the layers are stitched together all the way through. The filling is locked into place, sewn to the top and bottom of the shell, and so the comforter provides a nice, even warmth since the filling stays evenly distributed.

The Pyrenees PrimaLoft comforter will look great in your bedroom as well as perform greatly. PrimaLoft uses Ribbon Fiber Technology that is unique in bedding. It helps bedding maintain a "lofty" look and, when compressed, to quickly regain its loft. PrimaLoft also conforms to the shape of the bed in a natural, non-artificial-looking manner. The comforter's shell features an attractive stripe pattern and is made from 100 percent cotton in a 400-thread-count dobby weave.

Safe to clean at home in the washer and dryer, Pinzon's Pyrenees PrimaLoft comforter should not be dry cleaned. The full/queen-sized, medium-weight PrimaLoft comforter measures 90 by 96 inches.
