In terms of heat retention and the ability to be used as filling, these are the warmest fibers by weight:

• Qiviut [Musk Ox Wool]
• Yak Wool
• Alpaca Wool
• Camel Wool
• Sheep’s Wool

For more details, see my article explaining why these wools are ultrawarm.

After testing duvets filled with Camel, Alpaca, and Merino wool, I found that Camel wool is indeed the warmest inside a comforter.

All of these wools contain no lanolin so they are hypoallergenic and odorless.

They have good moisture “wicking” properties. This means that moisture is absorbed by the fiber. This keeps sweat away from being released to the outside of the duvet.

This is the duvet I found to be the warmest:

The absolute warmest duvet on the market is the Qiviut duvet:

Alpaca Duvet

This Alpaca duvet I have tested and it is also very warm:

• Ave Maria 400 GSM Alpaca Wool Duvet/Comforter

Qiviut (Musk Ox Down)

Qiviut (pronounced “kiv-ee-ute”) is the name for the downy hair of the musk ox. It is the warmest fiber in the world — about eight times as warm as sheep’s wool.

Muskoxen live in Alaska and Canada where temperatures sometimes drop to –100ºF (-73ºC), so they need protection. The Inuktitut name for the musk ox is “umingmak” meaning the “bearded one”.

Qiviut is an ultralight fiber and very soft fiber too. However, there is a limited amount of Qiviut produced every year, so it’s expensive.

In Alaska, qiviut is obtained from farmed animals or gathered from the wild during the molt. Unlike sheep, the musk oxen are not sheared.

Yak Down

Similar to qiviut, yak down is a very warm fiber that’s also lightweight and soft. It’s a more affordable alternative to the rare qiviut.

Yaks are primarily raised by nomadic Tibetan and Mongolian families. Their wool is combed once per year in the springtime.

According to Kora (a yak performance wear company), the wool is 40% warmer than merino wool. It has 66% greater air permeability and 17% greater water vapor permeability (tested with ASTM D1518, ASTM D737, ASTM E96).

Bison Down

Bison down is a very warm, insulating fiber. It is also very durable for such a soft fiber. It has a moisture regain of about 30%, compared to 18% for sheep’s wool — this means that even when saturated, the fiber draws moisture away from one’s skin.

There is only a limited amount of fiber available – estimated at 10,000 pounds per year versus 2,100,000,000 pounds of sheep wool.

It is harvested in Colorado and South Dakota, as a by-product of the bison meat industry.

Alpaca Wool

Alpaca wool is about three times as warm as sheep’s wool, and it is lightweight and durable. It contains no lanolin, which makes it hypoallergenic and odorless. Alpaca wool also has one of the highest moisture ‘wicking’ properties of all-natural fibers.

Alpacas are kept in herds that graze in the mountains of Peru, Bolivia, Ecuador, and Chile.

Other Wools

Other warm (and very soft) wools include llama, camel, angora, cashmere, vicuna, and guanaco.

Durability and Fineness

In terms of durability, bison is in most cases the strongest, followed by qiviut and yak down alpaca and merino.

In terms of fineness, any fiber that has a diameter of 20µ (microns) or less will feel very soft to the touch. In the alpaca world, the labeled “royal” alpaca should indicate fibers under 19 µ, “baby” alpaca should indicate fibers that are around 22.5µ, and “superfine” alpaca is 26µ.

There’s also an International Alpaca Mark that indicates the fiber is less than 28 µ.

In the merino world, look for wool labeled “ultrafine” (around 15-17 µ) or “superfine” (about 18-20 µ).

Here’s a list of fibers from finest to coarsest (in microns): 

• Vicuña (12µ)
• Angora rabbit (8 – 12µ)
• Suri Alpaca (10 – 15µ)
• Silk (10 – 13µ)
• Qiviut (11-13 µ)
• Cashmere Goat (14 – 19µ)
• Huacava Alpaca (15 – 29µ)
• Camel (15 – 22µ)
• Ultrafine Merino (15.5µ or less)
• Yak Down (17.5 to 19µ)
• Bison (14 -18µ)
• “Royal” Grade Alpaca (19µ or less)
• “Cashllama” Grade Llama (20 -21µ)48
• “Baby” Grade Alpaca (22µ or less)
• Mohair (23 – 28µ)
• Superfine Merino (15.6 to 18.5µ)
• Superfine Alpaca (26µ)
• Standard Sheep’s Wool (30 – 32µ)
• Human Hair (60 – 80µ)

Based on these criteria, these are the warmest woolens I could find:

• EBL 3.7V Li-ion Rechargeable Batteries — 3000 mAh
• Kiminors 3.7V 18650 Rechargeable Battery — 3200 mAh

Our recommended 18650 battery charger: XTAR VC2

About 18650 Batteries

What are the advantages of 18650 batteries? They are 3.7-volt lithium-ion batteries that can be recharged and are compatible with a wide range of electronics, including laptops, digital cameras, flashlights, and even electric car batteries.

Panasonic, Sanyo, Samsung, and LG are the top level 18650 cell manufacturers, making long lasting cells in a standard size (18 mm by 65 mm) that fits all 18650 compatible devices. Chinese knockoffs are available for cheaper but are prone to shorter lifespans and aren’t always uniform in size. As a rule, be wary of “protected” 18650 batteries, which have small circuit boards at the bottom that do not fit some electronics, such as flashlights.

High-drain batteries are safer and designed for high current devices, such as vaporizers. They are also less wasteful, meaning they have a longer life cycle and can last for more recharges.

18650 Battery Chargers

The best part about 18650 batteries is that they can be recharged. That means you will need a reliable charger to keep them energized and in working order. I like the XTAR VC2 charger because it has an informative LCD screen display.

The LCD screen tells you the real mAh capacity of your batteries, so you can make sure they are getting the advertised amount of fill or identify when they are losing efficiency.

Brightest Bike Light: Niterider Pro 3600 Lumen Light

The Niterider 3600 Pro is a 3600 lumen light made in the USA. This light has two chambers, and each chamber contains three Cree XML LED bulbs.

Niterider have a great reputation, and I’ve found their lights to be very durable — they’ve survived a few falls onto pavement from my bike.

This light is very bright and projects a wide beam hundreds of feet. A unique feature of this light is the included DIY software, which allows you to customize the settings it to your needs.

Brightest Bike Light With Built In Battery

Note that the light’s beam is just too bright to use in an urban area, unless you greatly step down the intensity! If you feel you’ll be doing this, you might consider the 1800 Lumen Niterider or the 1200 lumen Niterider.

Almost every professional Christmas light installer uses conical LEDs for their displays. Conical LEDs are waterproof and snowproof because the LED is injected molded into the plastic cordage. Conical LEDs are also 25% brighter than an incandescent indoor Christmas light. The brightness comes from the intensity of the LEDs and the magnification of the conical lens.

The Details On Conical LED Lights

Overall, LED lights are a great choice for Christmas because the lights almost never fail, and they are impervious to freezing temperatures. They are also much more energy efficient than incandescent bulbs. For this reason you can string up to 40 sets of LEDs together, and plug them into a normal electrical socket.

Conical LEDs are not recommended for indoor use due to their intensity (M5 or C6 LEDs are a better choice inside).

Conical 5mm LEDs are available from Amazon.

Schott Zwiesel Glassware

Schott Zwiesel is a German company known for glassware innovation since 1872. They create break-resistant, chip-resistant, and scratch-resistant stemware. The crystal glass has added titanium for strength and zirconium for crystal clarity, making it dishwasher safe.

I have their glassware at home — the pieces are versatile and can be used daily, yet they are elegant enough to use on special occasions. They are slightly expensive, but the investment is worth it.

Schott Zwiesel is available on Amazon.

Duralex Picardie Tumblers

Duralex has been manufacturing tempered glassware in France since 1929. Their Picardie Tumblers are known for lasting decades — they will bounce several times when dropped on the floor and survive without a crack. The tumblers can also withstand a sudden thermal shock — the temperate glass can go from -4° F to 212° F without breaking. This means they can be used to drink hot beverages. Duralex glasses are also lighter and more elegant than similar tempered glass products.

Duralex went into court-ordered liquidation bankruptcy in 2006 but has since partnered with Emile Henry, an old French manufacturer of cooking ware, to return to production.

Duralex doesn’t offer any product warranty beyond a 21-day return policy. However, we found no tempered glass tumblers with an extended warranty.

Durlaex Tumblers are available from Amazon for about $18 for a set of six.

Fortessa Fortaluxe Vitrified Dinnerware

Fortessa is a dinnerware company line created by the German company Schott Zwiesel. Fortessa specializes in vitrified china dinnerware. The china is reinforced with alumina or magnesium oxide for durability and thermal shock resistance. The dinnerware is called Fortaluxe SuperWhite, and it is used in many restaurants around the world and is reasonably priced.

You can find Fortessa dinnerware on Amazon.

Pyrex Bowls

Pyrex is another brand of tempered glass products renowned for their durability. The Pyrex brand was introduced by Corning Incorporated in 1915. Today, Pyrex is owned by World Kitchen and Pyrex glass products are manufactured in Charleroi, Pennsylvania. Recently, there have been rumors circulating about Pyrex products. The rumors suggest that Pyrex products are made with inferior materials, prone to breakage, and manufactured in China. However, this lengthy article on the myth-busting website Snopes.Com, concludes that the rumors are false. Here is an excerpt from the article:

While it is literally true that the material used in manufacturing Pyrex brand glass bakeware has changed from borosilicate glass to soda lime glass, the brand’s current owner, World Kitchen, claims that changeover began back in the 1940s and long antedates Corning’s 1998 sale of the brand, stating that “The Charleroi [Pennsylvania] plant has produced PYREX glass products out of a heat-strengthened (tempered) soda lime glass for about 60 years, first by our predecessor Corning Incorporated, and since 1998 by World Kitchen. In fact, since the 1980’s, most, if not all consumer glass bakeware manufactured in the U.S. for consumers has been made of soda lime glass. Consumers should know that soda lime glass, such as that used to make PYREX glass bakeware, is significantly more resistant to breaking on impact than borosilicate glass and comparably resistant to breakage caused by severe temperature changes.”

World Kitchen itself states that it has received complaints from only “a very small number of consumers” about unexpected breakage. It notes that the Consumer Safety Product Commission has found no safety issue with Pyrex glass bakeware.

Pyrex Bowls are available from Amazon.

Le Creuset French Ovens

Le Creuset has been producing handcrafted French Ovens in their foundry in Northern France since 1925. Their cookware is made with enameled cast iron and is known for lasting decades. The Le Creuset foundry uses standard sand-casting methods to produce its cookware. After hand finishing, items are sprayed with two coats of enamel, and each is fired at 800 °C. The enamel becomes resistant to damage during regular use.

Le Creuset cookware has a lifetime warranty that the products are free from defects in material and workmanship.

If you want an equivalent American-made product, see Lodge Dutch Ovens. We choose to feature the Le Creuset French ovens because, based on our research, they have an edge in quality.

Le Creuset French Ovens are available from Amazon for about $235.
