Water Bottle Sleeves are a great way to keep your water easily accessible while also counter-balancing your backpack. Designed to fit 1L "Smartwater" bottles and similar, these sleeves will attach to the shoulder straps on just about any backpack.

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.

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

Our Airplane Travel Case is a useful addition for the jetsetting adventurer looking to blaze international trails. Slide your backpack inside to protect it when checking your backpack on to a plane. When you arrive, move the airplane case to the inside of your backpack and it doubles as a pack liner.

This full size roll top dry bag protects the entire internal contents of your backpack. This is a good option if you prefer to use non-waterproof stuff sacks instead of individual dry bags. It is also nice as an extra layer in very wet environments. It is sized to fill out the main compartment of any of our backpack sizes, and will fit most similar volume backpacks.

This is also available in a heavier material with a handle for dual-use as a protective Airplane Case for checking your backpack on an airplane.

Tired of bending over backwards to reach your water bottles? Our Aquaclip Kit allows you to to clip a water bottle to your backpack’s shoulder straps or belt so you have it easily accessible up front. It will fit any small water bottle with a standard size neck. The bottle can be popped in and out easily on the go. We find that it carries the weight of a 500 ml (16.9 fl oz) bottle well. If you're looking to carry a larger bottle, like the 1L SmartWater bottle, we recommend our Water Bottle Sleeve instead.

The Zpacks kit includes one AquaClip, two One-Wrap® Velcro bands for securing it to the daisy chain on your shoulder straps, and a rubber end cap so that the clip cannot slide out of the velcro.

Protect your backpack from pouring rain and muddy ground with our Pack Cover. Our pack cover is an ultralight option to keep your backpack dry, including the outside pockets. It includes an elastic clip to secure it from storm winds.

Consider a Pack Liner as an alternative, if you don't mind your outer pockets getting wet.

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 with Dyneema® Composite Fabric​ material 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.

Trek through damp forests with confidence and dry gear. This is a good size for multiple clothing items, a tent, or a down quilt. This size fits well horizontally in most smaller backpacks.

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.

Top straps are not compatible with the Nero backpack.
