-September 2010-
We just started taking orders again for backpacks, shelters, etc. There is currently a waiting list of about 4-6 weeks. Backpack and tent orders are custom built one at a time, but not necessarily in the order received. If you need your gear by a certain date for a trip just let us know and we will make sure it arrives on time.

Materials and accessory items are in stock and are shipping in a day or two as usual.  Thanks!  Joe & Sheryl
ZPacks™ "Zero" Stuff-Sack-Pack

Three Sizes to Choose From:

Size Small:
Volume: 1,000 cubic inches / 16.4 liters
Weight: 2 ounces / 57 grams
Body Dimensions: 9" wide x 6" deep x 19" tall

Size Medium  (equivalent to a Blast 20 w/o pockets):
Volume: 1,400 cubic inches / 23 liters
Weight: 2.3 ounces / 65.2 grams
Body Dimensions: 10" wide x 6" deep x 24" tall

Size Large (equivalent to a Blast 26 w/o pockets):
Volume: 2,000 cubic inches / 34 liters
Weight: 2.7 ounces / 76.5 grams
Body Dimensions: 12" wide x 6" deep x 29" tall

Three Materials to Choose From:

1.3 oz/sqyd Silicone Impregnated Nylon is lightweight, and inexpensive, but it will puncture if you aren't careful with it. Sil-Nylon is a good choice for a day pack or a casual backpack, the expected lifespan is about 1,000-1,200 miles.

1.5 oz/sqyd Cuben Fiber is difficult to puncture or tear and will last for a full 2,500+ mile thru-hike with some care. It can also be repaired easily in the field with duct tape. (Tape won't stick to sil-nylon). The Blast backpacks are made from this material.

4.2 oz/sqyd Dyneema X Ripstop is very tough and should last a long time. Choose this material if weight is not critical and you want a pack that can take abuse.

Description:

The Zero is built just like the regular backpacks except that by default it has zero pockets or options.

  • Leave the pack as is and use it for a food bag, or sleeping bag stuff sack that you can also carry on day hikes and peak bagging. You can compress the pack to any height with the draw cord - loop closure system.
     
  • Add pockets or a few options create a minimalist pack. *Some options such as a padded belt are only available on the standard packs.
     
  • Size small (without options) folds up tiny enough to fit in a Ziploc bag as shown.
     
  • All ZPacks gear has a one year warranty against defects in materials or workmanship.
The green backpack shown is Cuben Fiber size Small. The dark blue backpack is Sil-Nylon size Medium.

Add Options:
Backpacks are typically built right when you order with the options you specify. Not all options are available for the Zeros. Some options cost more because the regular packs already have attachment points sewn on whereas the Zeros do not. Shock cord for example requires that 7 attachment points be sewn in place.

Returns or exchanges are always accepted, even on custom built packs.
 
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.

Weight: .2 oz / 6 grams each   Price: $15 each
 
Material:
Location:
Center Pocket
A large center pocket is great for quick access items like food for the day, etc. Mesh is a popular choice since you can see your gear and it lets you dry wet clothing.

The dimensions of the pocket are 2" deep by 16" tall by the width of the pack you choose. (Roughly 300-350 c.i.)

Weight: .35 oz / 10 grams    Price: $18
 
Material:
Webbing Belt
A simple nylon webbing belt, available in .75", 1" or 1.5" widths, and various lengths. 1" is the most common width.

A belt adds stability, transfers weight off your shoulders, and allows you to hang the pack away from your back when its hot by loosening the shoulder straps.

I can also make this belt detachable but it adds about .2 to .3 oz.

If you prefer a padded belt please choose one of the regular backpacks.

Weight: 1.2 oz / 34 grams to 2 oz depending on size / length.    Price: $10
 
Belt Size:
Detachable:
Torso Height
The default height will fit an average person with a torso length around 19" to 21". The actual measurement on the pack is about 21" from the bottom of the belt to the top of the shoulder strap attachment. You can specify a different distance by setting the quantity in your shopping cart.

The default height is sized to fit me. I'm 5'9. The straps are attached slightly above my shoulders which I find helps take weight off of them.
Height:
Sternum Strap
A sternum strap using 1/2" nylon webbing and a side release clip is added to your shoulder straps at chest level. The strap can be moved between 3 positions, or can be removed.

Weight: .3 oz / 8.5 grams   Price: $8

Daisy Chain
1/2" width grosgrain webbing is added to the length of each shoulder strap. This creates loops for clipping items like a compass or watch to the straps, or for securing a platypus tube.

Weight: .2 oz  /  6 grams    Price: $10

Hydration Port
If you prefer to carry a Platypus style water bottle on the inside of your pack a covered, reinforced hole can be added to the side of the pack to string out the drinking tube. You can leave the bottle loose on top of your gear, or add a water sleeve below.

Weight: .03 oz  /  1 gram    Price: $4
Location:

Water Sleeve
An internal pocket is added to the backpack to hold a water bladder against your back. Fits a 2 or 3 liter Platypus or other similarly sized bladders. This is usually combined with the hydration port above.

Pictured is a Blast 20 backpack turned inside out with a 3 liter platypus.

Weight: .3 oz  / 8.5 grams    Price: $15
Top Strap
A 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.

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

Weight: .3 oz  /  8.5 grams    Price: $6

Joe Says: 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.
Base Shock Cord Straps
Two adjustable shock cord straps are added near the base of your pack. These can be used to secure a sleeping pad, a stuff sack, or other long item right below your pack's center pocket. The shock cord can be detached when not needed.

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

Weight: .3 oz  /  8.5 grams   Price: $9

Side Straps
A pair of shock cord straps are added to the sides of this pack. They can be added near the top of the pack, or at the middle of the pack, or both.

The top side straps allow you to stand tall items like a trekking pole, fishing pole, or umbrella in the side pockets. They are also good for clipping small items like a hat, and for compressing the pack.

The middle side straps let you secure tall water bottles (3 liter platypus shown), or use both the middle and upper straps together to lash on a tall stuff sack or sleeping pad to the side of the pack.

This includes four small attachment loops that are sewn to your pack per pair.

Weight: .3 oz  /  8.5 grams per pair  Price: $9 per pair
Location:
Shock Cord Lashing    popular
3/32" Shock cord is criss-crossed along the front of the backpack. It can be used to compress the pack, or to strap on 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: $12

Joe Says: In my experience the extra compression isn't necessary, but this is useful for securing items like wet clothing, wet tent etc.
Haul Loop
A simple hand loop is added above the shoulder straps for lifting the pack. If you choose not to add this just grab a hold of the top of the pack to lift it.

Weight: .03 oz  /  1 gram   Price: $2
 
Ice Axe Loops
A pair of loops are added at each side of the pack for securing one or two ice axes, one at each corner. The head of each axe secures through a loop at the bottom, the handle is kept tight at the top with a shock cord band. The loops can all come off when you aren't carrying axes.

This includes two small attachment loops that are sewn to your pack per side.

Weight: .05 oz  /  1.4 grams per side    Price: $4 per side
 
Location:
Shoulder Pouches
These clip to your shoulder straps and are an excellent spot for your camera, GPS, phone, 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. These are detachable and can be used on non-ZPacks backpacks as well.

These are available in white or green cuben, or blue or black sil-nylon.
