So my current favourite bit of equipment is not a camera or accessory but a pair of trousers! The Craghoppers kiwi fleece lined trousers are a god send this time of year.
Furry Trousers to keep you warm and snug
On a cold winters morning fleece is your friend and combined with a practical outer shell they are perfect for standing leaning on your tripod and wondering if the sun will ever come up.
The slightly baggy fit is ideal for those really cold mornings when you need thermals underneath. I love em, if only they had cargo pockets to put your filters in like the standard Kiwi trousers do, they would perfect.
Highly recommended to keep your uglies snugly.
