Easy to use. Enough support to be able to slide bottle in and out. Elastic loop holds the bottle in when bending over. Top notch!! Thanks, Zpacks.

Water Bottle Sleeves are a great way to keep your water easily accessible while also counter-balancing your backpack. Designed to fit most popular tall slim 1L bottles such as Smart Water, Body Armor, Essentia and similar, these sleeves will attach to the shoulder straps on just about any backpack.

Keeps your cell phone secure and handy when you need it for navigation or to take a picture. Pouch weighs next to nothing; a must for every serious hiker. I highly recommend this product.

– Paul G., ★★★★★

Shoulder Pouches are the ideal place to keep your small camera or phone in reach for taking quick photos. The main compartment of the shoulder pouches are a good size for your wallet, car keys, map, headlamp, mittens, sunglasses, candy bars, pack towel, GPS, or any other items you would like to have within easy reach. The pouches carry comfortably on your shoulder, and you will hardly notice them there.

The small exterior mesh pocket can be used to store your small items like lip balm, emergency whistle, or a compass.

Designed for the adventurer on the go, our Shoulder Pouch w/ Zipper is the ideal place to store items that you need on the ready, like a small camera, your wallet, a map or your smart phone. The streamlined design carries comfortably on your shoulder, and you will hardly notice them there.

The small exterior mesh pocket can be used to store your small items like lip balm, emergency whistle, or a compass.

The belt pouches on Zpacks are one of the many selling points for their products. They are roomy, easy to access and are superior to that offered on any other pack I've used!

– Cristy G., ★★★★★

Be prepared for whatever the trail may bring by keeping your essentials close in hand with our belt pouches. These pouches clip securely to a padded belt, like on our Arc backpacks. There is plenty of space for a headlamp, folded maps, snacks, hat and gloves, gadgets, you name it.

If your backpack has a webbing belt, try Belt Pouches with Pads.

Really glad I bought this pouch—it works with my pack’s waist belt, it’s practically weightless, and it’s the perfect size for phone, compass, map and a few snacks.

– Charles Y., ★★★★★

From the summit to the streets, the versatile Front Utility Pack Accessory provides quick and easy access to all your essentials.

With plenty of space for your phone, a camera, a jacket or snacks, the ultralight F.U.P.A. can be worn as a stand-alone item while bagging a peak or for a night out on the town.

Leave the webbing belt at home and connect the F.U.P.A. directly to one of our backpacks for the ultimate pack accessory.

Really appreciate the ability to carry it different ways and to carry it alone on days in town. Saves much time and aggravation as you can get to most things you need during your hike when carried on your chest.

– Mark B., ★★★★★

This versatile four-in-one backpack accessory is one of our most popular items.  The ability to choose between four different configurations helps make the Multi-Pack the perfect companion for just about any adventure.

This thing was easy to attach and very lightweight. It will help me not lose track of IDs and cash in the bottom of my pack!

– Karen J., ★★★★★

Make sure you don’t lose your most important items. Attach this stick-on key zip pouch to the inside of your backpack, and your keys, wallet, passport, smartphone or other valuables will still be where you left them at the end of your hike. When you get to town the pouch detaches and fits in your pocket.

Just peel off the brown paper backing from the included flat clips and attach the pouch inside your backpack where you want it. We usually stick it towards the top of the backpack right behind the shoulder straps so that it is easy to get to. The adhesive bonds well and will also work on any urethane coated backpack material. Spare Stick on Flat Clips are available if you want to clip this pouch to a second location.

The strap held my bear canister very well for my trip to the Adirondacks where a bear canister was required. Great product.

– Glen F., ★★★★★

Our V Top Strap adds additional stability when you’re carrying heavier items on the top of your backpack. It is a little bit more secure than the standard, single top strap.

It can be used to carry a bear canister so long as the canister can squish into your gear as shown. Alternatively, a canister can also be carried standing vertically inside the pack.

The V Top Strap is modular and can be added or removed from your pack as necessary. Our normal, single top strap is also included when you add this option.

These Top straps are not compatible with the Nero backpack.  If you need a V Top Strap for your Nero, you'll can purchase one specifically designed to work with one here.

Simple and great to use and helps compact smaller loads.

– Christopher C., ★★★★★

Our detachable Roll Top Closure Straps let you cinch the roll top down to the sides of the backpack, rather than simply clipping it together. If you add these, you still have the ability to secure the top of the pack the normal way by clipping the top to itself.

Made in the USA.

*These are NOT compatible with our Nero Backpack.

The shock cord really helps to compress my pack down while also making it more functional. Great place to hold wet rain gear to dry or hang clothes to dry while hiking. I believe the shock cord is a must have. It adds more versatility and additional storage options.

– Daryl H., ★★★★★

The Shock Cord Lashing add-on can be used to hang items off your pack to dry, or to strap on additional items. The 3/32" shock cord is laced across the front of the backpack over the mesh pocket. The shock cord can be detached when not needed.

Made in the USA.

*This is NOT compatible with our Arc Zip or Arc Haul Zip backpacks.

I love them. They work great for my trekking poles and fishing pole !!!

– Scott B., ★★★★★

When the terrain levels out or you’re strolling into a trail town, trekking pole holsters are a great way to stow your trekking poles out of the way. These are convenient if you want to quickly store your poles for climbing, road walking, or other situations where you prefer to have your hands free.

This item includes two pairs of adjustable shock cord loops.  Attach them to your shoulder straps and belt at each side of the backpack to temporarily hold a trekking pole at either side.

This item has saved many a hike through scorching temperatures and inclement weather. Great product. Will never hit the trail without it.

– Christian D., ★★★★★

The Umbrella Holster allows you to keep your hands free while protecting yourself from the rain and sun with an ultralight umbrella. It easily attaches to the daisy chain on most backpack's straps. In calm weather you can keep both hands on your trekking poles, while in strong wind or driving rain you can rest one hand on the umbrella to control the angle.

The Umbrella Holster consists of a clip and an adjustable shock cord loop that attaches to your shoulder strap.

Attach the buckle above the sternum strap on your strap's daisy chain and then attach the shock cord loop at the bottom of the daisy chain.

Insert your umbrella into the clip and then cinch the shock cord tight around the umbrella’s handle.

Perfect for use with our Lotus UL Umbrella.

These pockets are perfect for a few bulky items that I like to bring on my trips. I highly recommend them!

– Michael H., ★★★★★

Sometimes an adventure calls for a little extra space. Our modular Top Side Pockets allow you to carry extra gear (like your cooking pot or rain gear) on the outside of your pack while still being able to accommodate taller items (like trekking poles, an umbrella, or a fishing pole) behind the pockets.

This is one of those items that goes unnoticed when working properly. After a couple of long trail days I am happy to report it works as advertised. It’s worth the money. The thing I like most about it is it’s thick enough to shine under heavy load while remaining thin enough to go unnoticed on a light carry. It adds versatility to an already great pack. I don’t have any thoughts on how this could be improved currently.

– Kevin G., ★★★★★

Our Arc backpacks include a full-wrap padded belt. If you need a little extra padding in the lumbar area our detachable lumbar pad can double up the existing padding. The lumbar pad slides on and off the Arc belt as needed.

These are NOT compatible with our Nero Backpack.

The loops fit my pack perfect and my ice axe perfect. What can I say...they’re perfect!

– Jerry C., ★★★★★

When your adventure calls for traveling along snowy ridgelines or climbing icy peaks, the ice axe loops are the perfect addition to your backpack. A pair of loops are attached at each side of the pack for securing two ice axes. The head of each axe secures through a loop at the bottom, and 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.
