Add Options:
Backpacks are built when you order them with the options you specify. Returns or exchanges are always accepted, even on custom built packs.
Sternum Strap  included!
A sternum strap made from 1/2" nylon webbing and a side release clip is added to your shoulder straps at chest level. It can be moved between multiple positions, and it comes off if you don't need it.

This is included in the price and weight.
Side Pockets
These pockets are the same as the pockets on the regular packs. They are sized to fit 1 or 1.5 liter bottles, and are positioned low on the pack and slanted forward for easy access without removing the pack. 2 or 3 Liter platypus style bottles will also fit.

All pockets have drain holes in the bottom to drain rain water. (Roughly 135 cubic inches each)

Weight: .4 oz / 12 grams each   Price: $20 each
Mesh Center Pocket
A large center pocket is great for quick access items like food for the day, clothing etc. Mesh is a popular choice since you can see your gear and it lets you dry wet clothing. Mesh will hold more than a solid pocket since it stretches.

The dimensions of the pocket are 3" deep by 16" tall by the width of the pack you choose. Roughly 500 cubic inches / 8.2L.

Weight: .7 oz / 20 grams    Price: $20

Water Sleeve
An internal pocket is added to the backpack to hold a water bladder against your back. It fits a 2 or 3 liter Platypus or other similarly sized bladders. String the drinking tube out the top of the pack.

Weight: .3 oz  / 8.5 grams    Price: $20
Top Strap
A 1/2" webbing top strap is added to the top center of your pack for lashing an item above your pack's center pocket. Perfect for a stuff sack with rain gear, a sleeping pad, snow crampons or other items. The strap is detachable when you don't need it.

A top strap is extremely convenient for stowing rolled up rain gear in on and off rain, or for lashing a stuff sack of gear when the main body of your pack is full to the top with food.

Weight: .5 oz  /  14 grams    Price: $10

Shock Cord Lashing
3/32" Shock cord is criss-crossed along the front of the backpack. It can be used to strap on items like wet clothing or a wet tent, snow shoes or other items. The shock cord can be detached when not needed.

This includes seven small attachment loops that are sewn to your pack.

Weight: .5 oz  /  14 grams    Price: $15
Haul Loop
A simple webbing haul loop is added above the shoulder straps for lifting the pack. If you choose not to add this just lift by grabbing the top of the pack, or the straps.

Weight: .1 oz  /  3 gram   Price: $5
Shoulder Pouches
These clip to your shoulder straps and are an excellent spot for your camera, GPS, phone, sunglasses, or other items that you want to grab quickly. Mesh on the front of the pouch gives you additional storage for small items like chap stick, keys, etc. They can also be used for .5L water bottles to counter balance a small pack.

These are detachable and can be used on non-ZPacks backpacks as well. They are symmetrical and can be switched left or right.

Weight: .5 oz  /  14 grams each   Price: $25 each / $45 pair
