Equipment
If at all possible, it is highly recommended you visit a local club or group and try equipment before purchasing. Some mushing groups will have complete fitment sets of harnesses from various manufactures, and members will own scooters and other gear of various brands that you can see in person and get their candid opinion on what works. Worse case, join one of the online mushing communities and ask for recommendations.
The lists below are all gear that we have used in our local mushing group and recommend.
