Insulated with 800 fill energy down, it’s surprisingly cheap in comparison with comparable jackets that price two or 3 times extra. If you would like a down hooded jacket that can preserve you heat right down to 23°F (when worn with a fleece mid-layer) and also you don’t thoughts the jacket’s barely outsized hood, the MT100 is a superb purchase at simply $119.

Forclaz is turning into Simond. It’s possible you’ll obtain a product labeled with both title. It options the identical design and high quality, however with a brand new model label.

Building
The Decathlon Simonds MT100 is insulated with 800-fill energy RDS-certified duck down, which is considerably uncommon for a jacket at this value, as most lower-cost down jackets are sometimes insulated with 650-fill energy down.

Duck down is cheaper than goose down, nevertheless, as a result of there’s a a lot bigger provide of it.
The MT100 incorporates a sewn-through baffle design, the place the inside and exterior materials are sewn collectively to create pockets that maintain the down insulation. Whereas some warmth can escape on the seams, this system is the norm on budget-priced down jackets as a result of it’s less complicated and cheaper to stitch than the field baffled design discovered on hotter and dearer jackets.

Match
The MT100 in a males’s XL measurement is true to measurement, however I usually put on a measurement massive, and would advise sizing up. The hood is massive and non-adjustable. Whereas its opening is bordered by elastic, it’s too loosely tensioned to shut the hole between the hood and one’s face. We advocate you put on a fleece or wool hat when utilizing the hood to maintain your head hotter.
Advice
The Decathlon Simond MT100 Hooded Down Jacket is an reasonably priced, packable down puffer jacket, insulated with 800-fill energy down, and is priced decrease than comparable jackets provided by different producers. For those who solely want a down jacket for three-season climbing and backpacking use to maintain you heat to about 40 levels, then it’s a fairly good worth for the cash, like lots of Decathlon’s different merchandise. Nevertheless, in the event you require a jacket for prolonged use in colder circumstances, I like to recommend getting a heavier jacket with a greater hood and extra down insulation. Decathlon additionally provides a hoodless down jacket referred to as the Simond MT500, which incorporates a 32°F consolation score and could also be an appropriate different. The benefit of a hoodless jacket is that it may be worn beneath a hooded rain jacket or winter shell extra simply than a hooded puffy.
