Mountain Laurel Designs Soul ProVent Bivy

You can use it as a standalone shelter in mild, dry conditions, but it is primarily designed to be paired with a tarp during rain or storms. Because the bivy is a single-person enclosure, a tarp provides the necessary overhead protection to keep the bivy's breathable fabric from becoming overwhelmed by direct precipitation.

The hoop is designed to be lightweight and collapsible, so it packs down easily alongside your sleeping bag or quilt. It adds minimal bulk to your pack and significantly improves comfort by keeping the fabric off your face while you sleep.

Yes, the ProVent 2.5-layer laminate is specifically engineered for high breathability, with a 30,000+ MVTR rating. While some condensation is inevitable in any enclosed bivy system, this material is significantly more effective at moisture management than standard coated nylons.

The 20D SilPoly floor is a durable, reliable choice that offers a balance of weight and abrasion resistance. The DCF (Dyneema Composite Fabric) option is lighter and completely waterproof, making it the better choice if you are strictly focused on shaving every possible gram from your base weight.

The Soul ProVent is cut with a mummy shape to prioritize weight savings, so it is best suited for standard-width sleeping pads. If you use an extra-wide or thick inflatable pad, you may find the fit quite snug, which can compress your sleeping bag's loft.
