Does this bivy keep rain off on its own?

The Splash Bivy protects against ground moisture, splatter, and wind-blown precipitation, but it is not a fully waterproof shelter. For rain coverage, pair it with a tarp overhead. The mesh canopy and nylon shell handle condensation and light mist, but you'll want a tarp if steady rain is forecast.

Which size should I choose?

The Regular fits sleeping pads up to 72 inches long and weighs 5.55 ounces. The Long accommodates pads up to 80 inches and weighs 6.29 ounces. Choose based on your sleeping pad length to ensure your feet stay inside the bivy's protected zone.

Can I use this without a tarp?

Yes, the Splash Bivy works as a standalone shelter on dry nights. The mesh canopy provides full bug protection and the bathtub floor keeps ground moisture out. Many users carry it solo for fair-weather trips and add a tarp when conditions call for overhead coverage.

How much room is inside?

The bivy fits closely around a sleeping pad and bag, with just enough clearance to move without pressing against the mesh. There is no room to sit up or store gear inside. It is designed for sleeping, not for living space, which is how it stays so light.

Is Dyneema more durable than silnylon for the floor?

Dyneema Composite Fabric resists punctures better than coated nylon and does not absorb water, so it stays waterproof and will not sag when wet. It is also significantly lighter for the same strength. The material does not rely on a coating that can wear off over time.

Why it's on GiftsFeed

Ultralight bug shelter with nine-inch waterproof walls

Most bivies either add so little protection they feel pointless or seal you inside a clammy cocoon. The Splash Bivy solves both problems: tall bathtub walls that actually stop splatter and mud, and a fully mesh top that breathes. The nine-inch floor height matters when you're camped on sloped ground or when a storm blows mist sideways under your tarp. Dyneema construction means the floor won't soak through after a week of damp camps, and at five and a half ounces it costs you less weight than an extra stuff sack. For anyone who tarps or cowboy camps, this is the bivy that earns its space in your pack.

Good gift when

The maker

Hyperlite Mountain Gear builds ultralight shelters and packs in Biddeford, Maine, focusing on Dyneema Composite Fabric for strength-to-weight performance. The company emerged from the thru-hiking community and designs gear for long trails where durability and low weight both matter. Their shelters prioritize modular setups that let users adapt coverage to conditions without carrying excess material.

The details

The Splash Bivy wraps your sleeping bag in a tall bathtub floor and a mesh canopy, giving you ground and insect protection that weighs just over five ounces. Unlike flat ground cloths, the nine-inch Dyneema walls create a barrier against wind-driven rain and wet terrain. The no-see-um mesh top keeps mosquitoes and biting flies outside while letting air move freely through the shelter.

The floor uses three-quarter-ounce Dyneema Composite Fabric that resists punctures and stays waterproof without a coating that can wear away. Above, a seven-denier ripstop nylon shell treated with DWR adds coverage from condensation and light precipitation. The bivy works alone on clear nights or pairs with a tarp when weather threatens.

Two size options accommodate different pad lengths. The Regular weighs 5.55 ounces and suits standard sleeping pads up to seventy-two inches. The Long version adds three-quarters of an ounce to fit pads up to eighty inches, giving taller users full coverage without cramped feet.

The design keeps setup simple: lay it flat, slide your pad and bag inside, and you're sheltered. No poles, no stakes required for the bivy itself, though you'll want a tarp overhead if rain is likely. The compact pack size disappears into a corner of your pack, leaving room for the rest of your kit.
