    How you can put the Ultra Bivy to good use.

    One of the benefits of using the Ultra Bivy is that you can save weight, increase space inside the tent and the enclosed nature of the Bivy is generally warmer than using the tent's inner, especially in winter.

    Winter/Spring and Autumn

    Replace the tent inner with the Ultra Bivy which lightens your load during a period  when you will have maximum weight in your pack. Increase the space inside your the tent for those long nights and increase warmth due to the enclosed nature of the Bivy compared to the inner.   The Optional Hood for the Bivy will give additional protection of draughts.

    Summer - during bug season

    This is the time when your inner will give most benefit. The increased weight is offset by the fact that you will have a lighter sleeping bag or quilt and less insulated clothing to take.
