Splash Bivy

Jump to: Our Verdict / Features / Specifications

Lean, light, and just enough—this bivy is for moving through the miles, not lingering in them.

Hyperlite Mountain Gear says says: 

For backpackers, thru hikers, or fastpackers that value high mileage days over long afternoons and evenings at camp, the Splash Bivy supplements sleep systems with basic coverage that can be used on its own on dry nights, or paired with an 8 x 10 Flat Tarp or Mid 1 Tarp in wet conditions.

Slide your sleep system into the Splash Bivy for an extra barrier of protection in wet or buggy conditions. When paired with a tarp, the tall bathtub floor walls help keep you drier and protected from rain, or use it on its own on clear nights.

Our Verdict

The Splash Bivy offers streamlined protection with minimal fuss for fast, light missions where every gram counts.

At 158g, the Hyperlite Mountain Gear Splash Bivy is built for those who’d rather be moving than lounging. Paired with a tarp, it offers a reliable barrier against bugs, splashback, and damp ground—ideal for racing weather or the daylight. The tall DCF bathtub floor inspires confidence in heavy rain, and the mesh top keeps the midges at bay.

The headroom is tight, especially if you use a thick sleeping pad, and it’s clear this bivy was designed more for shelter than lounging. The tapered footbox means mummy-shaped pads are easily accommodated; however, if you prefer a large rectangular mat like me, you may need to rethink your sleep system.

While I wouldn’t choose it for a lazy weekend in the woods, it’s a solid choice when covering ground is the priority and comfort takes a back seat.  If I were planning to use the bivi over an extended period, I would use it with a ground sheet.
