Throws and blankets are essential for keeping warm and cozy, especially during the colder months. When selecting a throw, warmth is often the most important factor. The warmest throws will be made from materials that provide superior insulation against the cold. Certain characteristics like thickness, weight, and fabric type determine how warm a throw will be. With so many different throws available, it can be challenging to determine which options are the most suitable for keeping you toasty.
How Throws Keep You Warm
Throws help retain body heat and maintain a comfortable temperature. They work by trapping heat close to the body and preventing it from being lost to the surrounding air. Several key factors contribute to how well a throw is able to contain and circulate warmth:
Fabric: Certain materials like wool, cashmere, fleece, and faux fur do a better job of insulating against the cold than thinner fabrics like cotton or linen. The natural fibers in wool and cashmere provide superior warmth and heat retention. Fleece and faux fur are synthetic options that emulate the thick pile of wool.
Weight: In general, the heavier and thicker the throw, the warmer it will be. Heavier throws have greater density to their fabric weave which traps more air and generates better insulation. Lightweight throws under 2 lbs work well for warmer weather but are less ideal for the coldest temperatures.
Construction: Throws made with tightly knit stitches or woven with a tighter thread count will hold heat better than loosely crocheted or woven fabrics. Tightly constructed throws limit airflow which helps retain body heat.
Size: Larger throws that can fully cover the body provide better insulation than smaller lap blankets. More coverage equals better heat retention.
Texture: Throws with soft, fluffy, plush, or shaggy textures hold heat better than smooth, flat fabrics. Air gets trapped within the fibers and yarns which improves insulation.
The Warmest Throw Fabrics
When searching for the warmest throw, pay close attention to the fabric type. These are the best materials for heat retention:
Wool: One of the warmest fabrics available, wool excels at trapping body heat while remaining breathable. The crimped fibers create millions of tiny air pockets that provide excellent insulation. Wool also continues insulating when damp. Organic wool, alpaca wool, cashmere wool, and merino wool are luxurious options.
Fleece: Known for its softness and warmth, fleece is a popular synthetic fabric made from polyethylene terephthalate (PET). The texture helps retain heat and fleece dries quickly. Microfleece and sherpa fleece have added pile for extra coziness.
Faux Fur: The lush, fluffy texture mimics genuine shearling while remaining completely animal-free. Faux fur throws are extremely warm and soft to the touch. They come in a wide range of styles, from short-pile to long-shaggy.
Cashmere: Rare and luxurious, cashmere wool comes from Cashmere goats. The long, fine fibers create a supremely soft feel and provide excellent insulation. True cashmere throws are expensive but offer unrivaled warmth and comfort.
Alpaca: The ultra-soft fleece of Alpacas makes for a wonderfully warm throw. Hypoallergenic with thermal properties on par with wool, alpaca fibers are durable and antimicrobial. Both woven and knitted alpaca throws provide cozy warmth.
Cotton Flannel: Cotton flannel throws have a brushed nap that makes them perfect for fall and winter use. Lightweight 100% cotton gives breathability while the fluffy texture holds in heat. Cotton flannel gets softer over time.
What Makes a Throw Warmer?
Beyond fabric, several other factors determine the warmth level of a throw:
Weight – You’ll want a throw around 2 to 6 pounds for optimal warmth and insulation. Heavier weight throws use more material which traps more heat.
Density – Fabrics with a tighter weave or knit and higher thread count hold heat better. High density throws limit airflow.
Loft/Pile Height – Throws with thick, fluffy pile or shaggy texture hold heat by trapping air within. Fleece, faux fur and wool have excellent loft.
Size – Bigger throws around 50″x70″ can cover more of your body for warmth. However, small lap blankets can also provide concentrated warmth.
Layering – Layer lighter throws for better insulation. Use a decorative top throw over a thermal blanket.
Choosing the Warmest Throw for You
When selecting an ultra-warm throw consider these factors:
Climate – In very cold climates, choose a heavy wool or cashmere throw. In temperate regions, lightweight fleece or flannel may suffice.
Use – If using in bed, larger sizes around 60″x80″ work well. For sofas, a 50″x60″ throw offers ample coverage.
Care – Determine whether a throw is machine washable or must be dry cleaned. Wool and cashmere require delicate cleaning.
Allergies – Wool and alpaca are hypoallergenic options if allergies are a concern. Avoid throws with feathers or silk.
Budget – Cashmere throws run over $200 while acrylics cost under $50. Set a budget and find the best material available.
Here is a comparison table of common throw fabrics and their relative warmth:
| Fabric | Warmth Level |
|---|---|
| Wool | Warmest |
| Cashmere | Extremely Warm |
| Fleece | Very Warm |
| Alpaca | Very Warm |
| Faux Fur | Very Warm |
| Flannel | Warm |
| Cotton | Warm |
| Acrylic | Warm |
| Polyester | Warm |
| Linen | Less Warm |
Tips for Use and Care
To get the most warmth from your throw:
– Layer throws over existing furniture or bedding for amplified insulation.
– Wrap a large throw completely around your shoulders and arms for a portable heat source.
– Choose throws big enough to cover from neck to feet for optimal warmth.
– Fluff throws regularly to maximize loft and maintain insulation.
To extend the life of a cherished throw:
– Wash gently by hand or using a delicate cycle when needed.
– Avoid excessive heat when drying; lay flat or tumble dry on low.
– Fold and store throws to prevent damage from pets, sunlight, etc.
– Spot clean stains immediately to avoid permanent discoloration.
– Use a fabric shaver to gently remove pills or fuzzy debris as needed.
Conclusion
The warmest throw for you depends on factors like climate, personal preference, and budget. Wool, cashmere, fleece, and faux fur are excellent options for cold weather insulation. Alpaca, flannel, and heavyweight cotton also rate highly for heat retention. Focus on thick, plush throws in larger sizes for staying cozy all season long. With proper care, a high-quality throw can provide years of unbeatable warmth.
