I have used this in summer and winter. The side pocket hold 1 qt Nalgene bottle. Many pockets inside to keep small things easy to find. It can be used to carry skis, snowshoes and trekking poles. Comfortable to wear for hours. It also works well as a carry on bag for flying. It has good capacity but fits under the airline seat.
