What an incredibly handy little thing! I’m one of those folks that hate hydration reservoirs inside my pack. I needed a handy way to attach a bottle to my pack’s shoulder strap and this is it. It holds bottles securely and allows easy access. Genius!
– John S., ★★★★★
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.
This clip is not designed to carry heavier water bottles. 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.

Ultralight Travel Toothbrush
Reasonably light. Tooth paste tube easily refills off a bigger tube with a little thought and allows me to brush my teeth twice a day for a week.”
– Brian J., ★★★★★
Make sure you have fresh clean teeth to lift your spirits without weighing down your pack. This ultralight, compact toothbrush includes an extension handle, a mini toothpaste tube, and a handy carrying case all for less than an ounce! If that is still too heavy carry only the parts you need.
The included toothpaste tube holds enough for a week or more if used sparingly. When it runs out, pinch the air out, butt it up tight against a normal toothpaste tube, and squeeze more in to re-fill it.
These are not returnable once the packaging is opened, unless there is a defect.
Foam Sit Pad
On my first backpacking trip with this item we had some very wet weather and I repeatedly found uses for this very light but super practical sit pad. It’s comfy to sit on but was also handy for kneeling on when dealing with wet gear or having a clean/dry place to put things on. Everyone in my family wants one now!!”
– Brandie L., ★★★★★
When it is time to stop for a meal or to relax and take in the views, our Foam Sit Pad will give you a dry, comfortable seat anywhere.

You can pull it out on breaks to keep your butt dry and padded, or tuck it into the foot of your sleeping bag for padding under your feet at night. It is blue on one side and black on the other.
This pad is included as back padding with our Nero backpack and Sub-Nero backpacks.

Blue Mini-D Carabiner (4 pack)
Nice to have some lightweight, small carabiners when hiking. Strung a line and used them to hold gear.
– Leon H., ★★★★★
At exactly one tenth of an ounce each these are the smallest and lightest carabiners around. They are perfect for clipping items to your pack, hanging your food bag, and many other uses. They are strong enough for almost any backpacking application, but are not meant to support a human's weight.
