Constructed from 3.1 oz/sqyd Dyneema® Composite Fabric (Hybrid).
Strategically placed attachment loops accommodate our most popular backpack add-ons like our Top Side Pockets, Shock Cord Lashing and Ice Axe Loops.
Three belt positions allow you to move the webbing belt up or down to fit a range of torso heights. The included belt is 1" (2.5 cm) wide and has a maximum adjustment of about 50" (127 cm) circumference. The belt contributes 1.2 ounces (34 grams) to the total weight. It can be trimmed down or removed.
Belt pouches with integrated belt pads are sold separately for those who desire more belt cushioning.
Integrated roll-top closure straps clip to the sides of the pack using the same 1/2” side release buckles featured on our Arc Series backpacks. The straps can be cinched to compress the pack's volume or used to stand tall items like trekking poles in the side pockets.
A closed cell foam sit pad measuring 11" x 15.5" (28 cm x 39.4 cm) is included and adds an additional 1 ounce to the total weight of the pack. The foam provides some cushion and support against your back. The sit pad is held in place with shock cord and comes off quickly for breaks. The shock cord (.3 oz / 8.5 g) and sit pad are removable and replaceable.
The shock cord can also be re-tied to accommodate up to 20" tall folded sleeping pads, or taller sit pads.
The pack material is waterproof. All seams and attachment points are taped with Dyneema® Composite Fabric Tape and the pack is constructed using hydrophobic thread, making the packs highly water resistant.
Comfy 3/8" thick by 2.5" wide padded contoured shoulder straps. The straps have a daisy chain for clipping on items, and an adjustable position sternum strap is included. The shoulder straps have 3D mesh on the underside which gives them a little bit more cushion.
Side pockets are sized to fit 1 or 1.5 liter bottles. They are positioned low on the pack and slanted forward for easy access without removing the pack. The pockets have drainage holes at the bottom, and elastic that keeps them tight at the top.
Large stretchy Lycra mesh center pocket is great for quick access items. Mesh also lets you dry wet clothing and gives you a clear view of your gear.
This pack can be folded up to fit inside a 1 gallon Ziploc bag. It can easily be packed in your luggage or used as a carry-on.
All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.
