Big Agnes Insulated Double Z Sleeping Pad Review

The Big Agnes Insulated Double Z sleeping pad is a lightweight, 3-season pad that combines internal stabilizing construction and PrimaLoft Silver Hi-Loft synthetic insulation to provide plenty of warmth and comfort against cold and hard surfaces.

The Insulated Double Z sleeping pad is filled with PrimaLoft Silver Hi-Loft synthetic insulation, which gives this pad an R-value of 4.5 and is rated to +15 degrees F (-9.4 degrees C).  When inflated, this pad is 4 inches thick and provides excellent shielding from the cold, hard ground.  Stabilizer construction throughout the entire pad distributes your weight evenly, creating a mattress-like feeling.

For an insulated sleeping pad, the Big Agnes Insulated Double Z is surprisingly light.  The regular size weighs 21 ounces (595 g), the regular wide weighs 26 ounces (737 g), and the long wide weighs 29 ounces (822 g).  It comes in a variety of sizes depending on your needs.  This mummy-shaped pad is available in three different sizes – Regular: 20 X 72 X 4 inches, Regular Wide: 25 X 72 X 4 inches, and Long Wide: 25 X 78 X 4 inches.  Packed dimensions are – Regular: 5 X 8 inches, Regular Wide: 5.5 X 10 inches, and Long Wide: 6 X 10 inches.  Also included with this pad is a mesh stuff sack.

The Insulated Double Z sleeping pad features a two-piece valve which permits one-way inflation and rapid deflation.  It is easy to blow up since you don’t have air blowing back out while you’re inhaling.  One downside is if you want to use an inflation pump, Big Agnes does not make one that fits the pad.


The one-way valve allows air in but won’t let air out when your inhaling for another breath.


Unscrewing the inlet valve allows for rapid deflation.

A repair kit in case off small punctures or cuts also comes with the pad and can be found on the inside pocket of the mesh stuff sack.  Also, Big Agnes provides a lifetime warranty for this pad and the cost is under $150 (Regular – $110, Regular Wide – $140, Long Wide – $150), which is an amazing bargain for this great piece of equipment.
