Features

Fast Footbox™ — Without zippers or a complex convertible footbox, the Core Bed’s simple patent-pending Fast Footbox™ technology utilizes just one hook to quickly transform the footbox from "mummy mode" for maximum warmth to “wide mode” for maximum space.

Clip Closures — To keep things lightweight and minimal, the Core Bed uses our proven clip system to connect the backpacking quilt to the separate fitted sheet and ensure a draft-free night of sleep.

Soft, Durable Fabrics — To maximize comfort, the Core Bed features our legendary soft sheet-like 50 d Pongee liner and a new amazingly supple and durable 30 d Taffeta shell.

The Kylie-curve™ — The 3/4 length baffle-backed Kylie-curve™ drawstring comfortably seals in warmth around your shoulders but leaves the edges free to drape at your sides or tuck into the sheet’s hood to block drafts.

Roomy Hood — The sheet’s roomy integrated hood insulates your head and arms and keeps your pillow in place throughout the night. Our insulated Core Sheet is filled with a soft synthetic, rated to -4 °C. Core Sheets are also available with an uninsulated hood if you're looking to ditch some weight (learn more below).

Thermally Mapped Baffles — We designed our quilts to maximize thermal efficiency, distributing down to provide warmth where it’s needed most. Smaller baffles minimize down-shift, vertical baffles around the upper body prevent down from sliding, and horizontal baffles on the top of the foot box keep down from shifting with foot movement.

RDS Compliant Down — The Core Quilts are filled with premium 650 fill-power down from Allied. This down is RDS (Responsible Down Standard) compliant.

I will NEVER go back to a sleeping bag!

"Absolutely zero regrets relying on my Core Bed setup. I have never been cold or uncomfortable and this is from someone who tosses and turns several times in the night as a side sleeper. My last outing was car camping (primarily a backpacker) and I slept with a full length body pillow for fun and had no issues. Love my Zenbivy!"

Rotisserie Chicken Approved

"I thought that Mummy bags were the top tier sleep solution for YEARS. The only problem, is that I sleep like a rotisserie chicken and I would wake up so tangled in my sleeping bag I would be near panic attack. Add in a new member to the family - a 7lbs Pomeranian - and the Mummy bag was absolutely no longer an option as there was no safe way for him to be in the bag with me without getting tangled up. I went out on a limb and spent a few extra dollars for the Zenbivy sleep system (core quilt and uninsulated sheet) and I have NO regrets! The quilt is rated a few degrees lower than my previous Patagonia sleeping bag, however it seems much warmer? No more getting tangled, doggo is safe and warm, and I can live my best unobstructed rotisserie chicken life."
