Though a tent or shelter found in our Ultralight Tent Review is the centerpiece of a floorless shelter system, modular components can significantly increase function and versatility. We recommend starting with our full ultralight review, but once you've finished up there, this article summarizes the types of available components and recommends several options for various applications.

Ground Cloths

Ground cloths are useful for protecting an inflatable sleeping pad from sharp objects that might puncture it. Polycro is our favorite material because it is lightweight (4 oz. for a two-person size) and cheap. Gossamer Gear sells it for $10. However, we rarely use ground cloths because they can be substituted by smart campsite selection, backpacks, packrafts, dry bag style pack liners, or are unnecessary if you sleep on a closed cell foam pad.

Bug Inserts

Inserts have a waterproof floor and bug netting canopy. They provide the most comfort in very buggy places and are the best value option for protecting two people from insects. They are also the most comfortable option for hot nights or for curling up with someone else or with a book. Many different companies make model specific inserts. We recommend purchasing a two-person version and suspect that the Zpacks Duplex 2 could be the best pyramid tarp. For A-frame and flat tarps the Hyperlite Mountain Gear Square Flat Tarp is the best we know of.

Bug Bivys

Bug bivis have a waterproof floor and bug netting that covers your sleeping bag. These are good for solo use in hot, buggy climates, but we find that inserts are more comfortable because they have more space and are a better value because two people can use them. An example is the Mountain Laurel Designs Bug Bivy.

A bug bivy, such as this one from Mountain Laurel Designs, can offer good protection from insects on hot buggy nights, but is a poor value compared to a water resistant bivy sack, which is more protective and versatile.

Water Resistant Bivy Sacks

For solo use we prefer water resistant bivy sacks to bug bivys because they are a better value and much more versatile. We also prefer water resistant bivys to inserts for winter use because they block spindrift and are warmer. Unlike climber style bivy sacks, which are made entirely with waterproof fabrics, water resistant bivys have a waterproof floor and sides, water resistant top, and bug netting in the head area. They serve as a ground cloth, completely seal out flying and crawling insects, block wind, stop spindrift, and add between 5 to 10 degrees of warmth. All for only 7 oz.!!
