Which The North Face jacket is the warmest?
The North Face’s premier Summit Series® outerwear features 800-fill down, which is one of the highest quality down fills commercially available and is considered by many to be the gold standard of insulation.
Are down-filled jackets really warm?
Goose down fill is the gold standard in thermal insulation, so down-filled jackets will definitely keep you warm. Some down-filled jackets are warmer than others, though, and this is determined by the fill power and the total amount of down used in the jacket – the higher the number, the warmer the jacket.
Fill power is measured by placing one ounce of goose down in a graduated cylinder and measuring the volume the down occupies in cubic inches. The North Face products are insulated with high-fill power goose down ranging from 500 to 800 fill, which represents the highest quality down commercially available.
With an unmatched warmth-to-weight ratio, down is highly compressible, ultra-light and amazingly warm, but only available in limited quantities, meaning it isn’t always widely available. The next best option is 800 fill down. The North Face uses this level of goose down in its L3 Summit Series jackets, and its Trevail and Impendor lines.
Is The North Face Moondoggy jacket warm?
The North Face Moondoggy kids’ jacket is designed to keep your kids warm and dry. It features a microfleece lining and 550-fill down thermal insulation, which is on the lighter end of the fill power spectrum but will keep kids warm and cosy for day-to-day use.
Higher levels of down fill are usually reserved for performance outerwear designed to be worn in very cold climates – and only the Nuptse and Massif ranges of kid’s jacket feature higher down fill, rated at 700. So if you’re looking for a day-to-day, down-filled jacket for your kids that will keep them warm and dry, the Moondoggy jacket should be the perfect fit.
