The Season's Best New Gear Traditionally, fall and winter are when you give up your “summer” sports. The bike gets a tune-up, three-season tents and bags get washed, and the trail runners go on the shelf until the snow melts. But, wow, have things changed. Fat bikes extend adventure cycling to four seasons. Lighter, more versatile insulations allow one garment to cover you from warmth of Indian summer to the chilly bluster of spring. New tents can handle winter’s blasts while weighing not much more than summer ultralights. Think outside the box? Gear manufacturers are thinking outside the season, and we’re all better for it.
