Uniqlo Ultra Light Down Jacket vs Decathlon Forclaz MT100 Down Jacket

The Uniqlo Ultra Light Down is the better pick for a light, packable layer under a coat or on mild days, and it looks clean enough for city wear. The Decathlon Forclaz MT100 is the better pick for actual cold-weather hiking: it adds an adjustable hood, zipped hand pockets, RDS-certified down and a stated comfort range down to about 23°F. Uniqlo's version is trimmer and more of a fashion-forward midlayer; Decathlon's is a purpose-built outdoor shell with a looser, layer-friendly fit. Owners of both praise the warmth-to-weight ratio, but Decathlon's hood and pocketing make it more useful outdoors, while Uniqlo's cut and finish feel more polished for everyday wear.

• Choose the Uniqlo Ultra Light Down if you want a slim, packable midlayer for commuting or travel and don't need a hood.
• Choose the Decathlon Forclaz MT100 if you'll wear it hiking or in real cold and want a hood, zipped pockets and a stated temperature rating.
