50D Pongee Liner
Our legendary 50D Pongee fabric is pure luxury. It's both durable, soft and—most importantly—has a similar feel to a sheet you would use at home, bringing a familiar kind of comfort to camp.
-
20D Nylon Shell
20D fabrics are much softer than traditional ultralight technical fabrics while being only a fraction heavier. They’re buttery-smooth, comfortable, and durable.
-
650+ FP Down
Our premium 650+ FP down is RDS (Responsible Down Standard) compliant and provides the best bang for your buck.
-
Synthetic
Built for warmer nights, tighter budgets, and personal preferences, we’ve used a polyester synthetic blend that’s as soft as it gets. So soft in fact you’ll swear it’s down!
Core Bed Details
-
Lightweight Clip Attachments
Core Beds feature our color-coded clip closures. They're nearly weightless, proven draft-free, and practically disappear when you're using the quilt on its own.
-
Zippers
Core ZipBeds use zippers to attach the quilt to the sheet. Zippers are convenient, familiar, and fast! They don't take much explaining.
-
Full-Length Sheet
All Core Beds feature a full-length sheet for full mattress coverage and maximum comfort at camp.
-
Adjustable Fit
Zenbivy sheets are designed to fit most standard size mattresses on the market, including rectangular and tapered styles.

-
Draft-Free & Constriction-Free
Zenbivy beds seal out cold air—keeping you warm without restricting your movement with straps.
-
Fast Footbox™
Unlike sewn footboxes that restrict your movement and do not vent, Zenbivy’s patent-pending Fast Footbox™ uses a single clip that allows it to expand for more space or narrow for more warmth.
-
Kylie-Curve™
Most quilts use a drawstring across the full width, which causes it to draft. Zenbivy’s baffle-backed Kylie-Curve™ solves this by cinching only the center, keeping the sides free to drape naturally or tuck into the hood, sealing out drafts at your shoulders.
-
Insulated Hood
Other quilts leave you exposed with no hood, or force you into awkward add-ons. Zenbivy’s sheet solves this with a built-in hood that insulates your head.
-
Semi-Rectangular Design
Most quilts are cut in an hourglass shape, creating a tight pinch point that twists and tugs as you shift in the night. Zenbivy quilts are semi-rectangular and will never pinch or grab, so you can move freely.
-
Thermally-Mapped Baffles
Other quilts rely on long, continuous baffles that let down shift and clump. Zenbivy quilts use smaller, segmented baffles engineered for thermal efficiency—keeping insulation evenly distributed and warmth right where you need it.
-
Headboard Clips
You wouldn’t strap your pillow to your bed at home, yet that’s often the only option in the backcountry. Zenbivy’s sheet feature built-in loops to keep your Zenbivy SoftTop™ Pillow secure without restricting how you sleep.
