Regardless of winter activity, these are the essentials worth addressing before October.
Outerwear
Laying out last season's jackets and shells and assessing them honestly is a good place to begin. Parkas and insulated layers benefit from conditioning before the cold sets in, and waterproofing on all outer shells should be refreshed. Snow pants and mid-layers: fleece, down vests, and puffers should be inspected for wear and cleaned before they go back into rotation.
Footwear
Soles and waterproofing on winter boots wear down gradually and are easy to overlook until conditions demand them. Leather boots benefit from conditioning now, before cold weather makes it less effective. Shoulder-season footwear, waterproof runners and hikers, is worth checking as well, as they tend to carry a lot of the load in the weeks before deep winter arrives.
Baselayers
Merino wool and synthetic thermal sets should be inspected for holes, stretched elastics, or reduced insulating performance. Base layers work hardest against the skin; worn pieces are worth replacing before the season begins rather than discovering the issue mid-winter.
Gloves and Mitts
Torn liners, broken closures, and dried-out leather are all common after a season in storage. Leather conditioning takes minutes and extends the life of a glove considerably. A well-rounded kit covers everyday commuting gloves, insulated mitts for the coldest days, ski or snowboard gloves with removable liners, and lightweight liners for layering. For a full guide, refer to our Glove Care 101.
Winter Car Kit
Ice scraper and snow brush, a compact shovel, a wool blanket or sleeping bag, a flashlight with fresh batteries, booster cables, and a spare set of mitts, a tuque, and hand warmers in the glove compartment.
