What Our Gearhead(R) Experts Are Saying:"The Infinity Down Jacket has become the first thing I reach for when the temperature drops and I don't feel like thinking too hard about what to wear. The 650 fill power duck down is genuinely warm for how light the jacket feels, and the ripstop fabric gives it enough durability that I am not treating it like something precious out on the trail."There is a version of winter where the cold is just part of the backdrop rather than something you are constantly managing. The Swix Infinity Down Jacket helps you get there. Built around 650 fill power 80/20 duck down housed in a rugged ripstop polyester shell, it delivers serious insulation in a package that feels light and unrestrictive, whether you are hiking a snowy ridge, running errands across town, or simply spending a long afternoon outside. The elastic-bound hood and cuffs seal out cold air without requiring any adjustment, the chin guard and storm placket close off the collar against wind, and easy-grip YKK zipper pullers mean you can make quick adjustments even with cold hands or gloves on. The adjustable hem lets you dial in coverage, and the reflective logo adds a low-key visibility detail for low-light conditions. The Infinity Down Jacket is the kind of reliable, go-anywhere layer that earns a permanent spot by the door from the first cold day of the season.
