We bought two of these backpacks last year used them for 60+ miles without issues. They are way more comfortable and lighter than our previous backpacks. We loved them, looking forward for our next backpacking trip this summer.

Fantastic move to the Arc Haul pack from a traditional internal frame type pack. Although I didn't really need a 70L pack, I decided to go with the biggest I could get as the top rolls down if compartment is not filled up.

I bought the Woman's Arc Haul Ultra with various add-ons. It is the most comfortable pack I've tried. I love the possibilities to customize it with all the add-ons!

First time I put on the Arc Zip Ultra 62L, I immediately noticed the difference—this was the best pack fit I’ve ever experienced. I thought my previous packs fit well, but the extra adjustability of the shoulder straps and hipbelt tilt on this model really took comfort to another level. 10kg has never felt this comfortable before. Highly recommended!

It is really the best backpack I have ever owned. Lightweight, waterproof (tested under strong rain), a lot of space inside and very well balanced all the weight goes in the hips so the shoulders are always relaxed. Love it 🥰

The Nero Classic is as as close as it gets to our original frameless backpack design which was tested on an Appalachian Trail thru-hike over 20 years ago. The Nero is compact and streamlined with only the most essential features for long distance hikers. Bomb-proof Ultra 100X fabric and waterproof taped seams can handle whatever nature throws at it. Gray, Green, Pink, and Red variations feature Ultra TenX fabric for an added pop of color.

Choose from multiple volumes to fit your hiking style. Three different interchangeable strap designs, an optional removable belt, a comfy sit pad, and a bunch of cool modular add-ons make the versatile Nero Classic your ticket to maximizing every day hike, section hike, or thru-hike.

Designed for advanced hikers who want their frameless pack to move fast and work hard, the Nero Pro takes the same streamlined, frameless philosophy that makes the Nero Classic a go-to for minimalists, long-distance hikers, and elevates it to technical territory.

Featuring premium Ultra TenX fabric and a full set of Stretch-Mesh center, side, and bottom pockets, the pack is purpose-built to give high-use storage areas an advanced balance of stretch, durability, and trail-ready function.

The back of the pack also gets a thoughtful performance boost, too, with a zippered 3D mesh sleeve that keeps the included foam sit pad secure and comfortable against your back.

Choose from multiple volumes to match the way you hike, then dial in the carry with interchangeable strap options, and a full range of modular add-ons. Whether you’re moving fast on a day hike, stretching miles on a section hike, or fine-tuning your thru-hike setup, the Nero Pro gives advanced hikers the flexibility to build a pack system around their exact style.

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.

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.
