How to choose between a tarp or a bivvy sack?

Tarp vs Bivvy: Location and Purpose

When deciding between a tarp and a bivvy sack, consider the location and your purpose. A tarp is ideal for staying dry in a specific location, such as a campsite or near a tree. It can be set up in various configurations, providing protection from the elements. A bivvy sack, on the other hand, is designed for rapid deployment in emergency situations, such as a sudden storm or when lost in the wilderness.

Setting Up a Tarp

To set up a tarp effectively, start by identifying two anchor points, such as trees or rocks. Use rope and a tarp clip to secure the tarp to the first anchor point, then use a ridgeline to tie the tarp to the second anchor point. This creates a simple lean-to configuration. For added protection, consider using a tarp pole or a makeshift ridgepole to create a more substantial structure.

Choosing the Right Bivvy Sack

When selecting a bivvy sack, consider the season and your expected temperatures. A bivvy sack with a waterproof and breathable fabric, such as Gore-Tex or similar technology, is essential for maintaining body heat and preventing condensation buildup. Look for a bivvy sack with a built-in hood and a zipper that can be sealed to prevent cold air entry. A bivvy sack with a built-in bug net is also a good option for warm weather use.
