Gear Review: Shadowlight Carbon 60 Backpack by Outdoor Vitals
The Outdoor Vitals Shadowlight Carbon 60 blends ultralight design with real-world structure. Featuring a carbon fiber frame, adjustable fit, and under-2-pound weight, this backpack is built for long miles, comfort, and durability- perfect for thru-hikers and weekend adventurers alike.
If you’re an ultralight backpacker who still craves durability and structure, the Outdoor Vitals Shadowlight Carbon 60 Backpack might just be your dream pack. It merges the strength of Carbon Fiber stays with the minimalist efficiency of ultralight design, creating one of the best balance points between comfort, weight, and performance in the 60L category.
First Impressions
Right out of the box, the Shadowlight Carbon 60 feels refined with its sleek lines, thoughtful pocket layout, and premium materials throughout. It’s clearly built with real backpackers in mind, offering the balance of simplicity and functionality that makes the difference when you’re logging 15+ miles a day.

Despite weighing in at just under 2 pounds, this pack doesn’t feel fragile. The body fabric (210D Robic nylon + UltraStretch mesh) has a durable feel, while the frame and carbon fiber stays give it the stiffness needed for comfortable load transfer even when carrying 30+ pounds.

The Shadowlight Carbon 60’s carbon fiber frame sets it apart from other ultralight options. It adds real structure and transfers weight efficiently, making it far more comfortable for long-distance hikers who don’t want to compromise on support.
On-Trail Performance
Once on the trail, this pack quickly proves it’s more than just a lightweight number on a spec sheet. The carbon frame system distributes weight really well across the hips, eliminating the typical shoulder fatigue that plagues many frameless ultralight designs.
The ventilated back panel keeps airflow consistent, and the padding on the hip belt is plush without feeling bulky. You can comfortably push this pack into the low-30-pound range, which is impressive for something this light.
The UltraStretch mesh pockets on the front is a perfect place for a rain jacket, filter, or cooking gear, while the side pockets easily fit two large water bottles or a tent pole kit. A top-mounted compression strap keeps everything tight and balanced when you’re running a lighter load.
Organization & Accessibility
Outdoor Vitals did a great job giving ultralight hikers what they actually need. The Shadowlight Carbon 60 includes:
- Two zippered hip belt pockets for snacks and small essentials
- A large internal hydration sleeve

- Roll-top closure that makes the pack adaptable from ~40L to 60L
- Front UltraStretch mesh pockets for quick access gear
It’s clean, streamlined, and efficient everything has a purpose. No unnecessary straps or flaps here.
Comfort & Fit
The adjustable torso system lets you dial in your fit perfectly, which is rare in packs this light. Combined with the flexible carbon stays, you get a ride that moves naturally with your body. It's perfect for long climbs, uneven trails, and those inevitable bushwhack moments.

The removable hip belt gives the Shadowlight Carbon a modular personality. If you’re going ultralight for a fast overnight, strip it off. If you’re heading out on a week-long trek, keep it on for added load support.
Pros & Cons

| Adjustable torso and removable belt for a custom fit | Not ideal for loads above 35 lbs |
| Made by a trusted ultralight brand | Slightly pricier than frameless packs — but worth it |
Field Notes

It’s versatile enough for thru-hikes like the Colorado Trail, but still comfortable enough for weekend backpackers who want to lighten their load without sacrificing support.

This is the kind of pack that disappears on your back. It carries smoothly, balances weight naturally, and holds up to real-world use. Outdoor Vitals nailed the sweet spot between comfort and minimalism.
