The Bach Bivy Heads Up Pro Regular is a one-person ultralight tunnel tent designed for solo backpackers who want reliable shelter without extra bulk. It provides just enough space for sleeping and gear, keeping things simple and light on the trail.

This bivy-style design uses electrospun fabric for both the outer and inner layers, cutting down overall weight while improving breathability. The groundsheet is made from 40D ripstop nylon with a TPU fire-retardant coating to stand up to rough ground, and the 7003 aluminum poles offer a stable structure. At only 0.8 kg, it slips easily into a minimalist pack and won’t weigh you down on long hikes.

Electrospun fabric is woven from very fine threads, creating a lightweight yet breathable barrier that helps reduce condensation. A 40D denier rating refers to the thickness of the groundsheet’s fibers—thick enough to resist wear but light enough for ultralight kits—and its ripstop weave prevents small tears from running. The TPU coating adds abrasion resistance and fire-retardant properties, and 7003 aluminum is chosen for its strong-to-lightweight ratio, keeping the tent both sturdy and portable.
