Hi Bridget,
Sorry for the delay in my response.
There are now 10 travellers booked on this trip. In regards to your husky ride, no clothing is provided. You will want a shell that's waterproof and breathable to stay warm when it's windy and dry when it's rainy. These thin, outer jackets should be fully waterproof, an outer shell made of Gore-Tex® material (including a hood) will keep a wet day from turning into a miserable one.
You may also want to consider taking an inner and insulating layer, along with a pair of gloves and comfy walking shoes as temperatures will be around 8 to 13 Celsius.
Kindest regards,
Monty
