This is a replacement for the standard sternum strap that attaches to the daisy chains on our backpack straps.

The sternum strap loops around the daisy chain webbing on our shoulder straps, and should also be compatible with other similar shoulder straps.

The maximum length is about 12" (30.5 cm) from strap to strap and will fit most hikers.

We also have a longer sternum strap available.

The Zpacks Titanium Trail Pen is a custom made ultralight upgrade for hikers who still believe memories are made with ink, not megapixels. Lock the pen into place with our precision-engineered channel system and let your ideas, trail notes, sketches, and discoveries flow. If your gear can outlast a thru-hike, your words should too.

Comfortable for left or right-handed writing. Writes when wet! Pairs great with a Waterproof Trail Notebook!

Includes a small keyring (.02 oz / 7g) and two ink refill cartridges (.02 oz / 7g each.) Refill cartridges can be found here.

Pen measures 3.25" (8.26 cm) long. Our tiny oval carabiners, or mini-S carabiners are small enough to fit the little hole on the end of the pen to clip to your pack.

 

Our side release buckles are slimmer, lighter, and stronger than the competition. These are adjustable on both sides and are commonly used for backpack belt buckles. They have a wide mouth and narrow prongs so they are easier to snap together without fidgeting.

A little thicker than the Nemo. It’s lightweight and does the job quite well.

These tiny 5g toothpaste tubes are the ultimate trail companion for adventurers looking to keep their smile bright and breath fresh in the wild. Slip it into your backpack, and you're set for overnights under the stars and those epic summit selfies.

It's lightweight and eco-friendly, ensuring your mouth stays fresh without weighing you down. Adventure-ready and travel-tough, this tiny tube proves that good things really do come in small packages!

The 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.

This toothpaste comes standard with the Trailbrush and our Ultralight Travel Toothbrush.

A flat buckle that doesn't rub you the wrong way. This slim buckle works with 3/4" (20 mm) binding tape. We use this on the neck of our sleeping bags, and on some clothing items where a protruding buckle would be in the way. The male side adjusts, and the female side does not. The buckles will break under high tension so they are best in applications where they aren't under a lot of stress.

Couldn’t be happier with this down hood. Perfect for quilt users, doesn’t slide around or off your head at night like a beanie can on straight, slick hair. Much better than the hood on a sleeping bag, which can slide into your face when you turn, and of course can’t be detached for use as a separate warm hood. The ultra light weight is remarkable. It’s very warm and has a cozy fit and feel.

– Rachel M., ★★★★★

Get ready for sweet dreams on cold nights when bundled up with the Zpacks Down Hood. A perfect companion to your ultralight down quilt, stay cozy and snug tucked away from the cold.

Zpacks Down Hoods are reversible, face whichever color you prefer outward.

These stick excellent to Dyneema® Composite Fabric gear, but they will not stick to silicone fabrics. The adhesive will stick OK to normal nylon or polyester.

A good night's rest isn't worth sacrificing. The Zpacks Padded Pillowcase adds luxury, and functionality to our Inflatable Pillow.

Soft Octa fleece is comfortable against your face, and a few layers of synthetic insulation adds a little bit of extra loft and cushion. 

Elastic straps on the back allow you to boost the height of your pillow with your sit pad, or any stuff sack or dry bag, and a shock cord strap secures the pillow to your sleeping pad to help prevent it from sliding.

This pillowcase is sized to perfectly fit our inflatable pillow, but it could also be stuffed with spare clothing like your Down Jacket. A zipper on the back of the pillowcase provides easy access to blow up your pillow, or to add or remove items.

These handy squeeze bottles hold 1 fluid ounce (29.5 ml each). They have a press-disc style top which is convenient to flip up and squeeze out small amounts. The top also screws off to fill it or empty it faster. These quality bottles won't leak or accidently come open in your backpack.

These are great for repackaging small quantities of shampoo, conditioner, sunscreen, moisturizer, hand sanitizer, and other cosmetics.

Throw it in the washer and dryer with your regular laundry.
