Review: Outdoor Vitals Carbon Evo 50 Backpack
The Carbon Evo is an ultralight framed backpack that balances low weight with a stable, comfortable carry and supportive suspension for reliable on-trail support.
Built around a carbon fiber suspension system, roll-top design, and simplified storage layout, the Carbon Evo falls into the ultralight sub-2 lb category of backpacks while still offering the support needed for typical loads.
Due to back issues, most ultralight packs I’ve tried haven’t worked well for me — they either create pressure points or don’t carry weight in a stable, comfortable way. The Carbon Evo is the first one that has felt comfortable enough for me to keep using.

Features
Roll-top + Y strap system
I prefer roll-top packs over top-lid designs. Top lids usually add bulk and extra hardware, and I rarely use them enough to justify it. I’d rather keep things simple and access everything through a single opening. The roll-top also helps keep the interior drier in rainy conditions. The Y strap on top makes it easy to secure bulkier items like a sleeping pad, jacket, or even a bear canister when needed.
Side pockets
The Carbon Evo has large, angled side pockets that make it easy to reach water bottles while hiking. I usually carry one bottle on each side for balance, and can grab them without stopping or taking the pack off. Behind the bottle pockets, I store items like tent poles and my backpacking chair. Compression straps on the sides keep them in place, and they don’t get in the way of bottle access.
Front stretch mesh pocket
The front UltraStretch mesh pocket is one of the most useful external storage areas on this pack. I usually keep my foam sit pad, tent footprint, fanny pack, and water filter here. It’s also useful for wet gear when I don’t want moisture inside the main compartment.
Hip belt pockets
These are some of the best hip belt pockets I’ve used on any pack. They’re larger than any I’ve used before, and are easy to open and close with one hand.
On one side, I keep items like my InReach Messenger, lip balm, sunscreen, small towel, spare camera batteries, and a bug head net when needed. On the other side, I keep snacks and electrolyte packets, and there’s still room to carry small items like my mini tripod.
Hydration sleeve + shoulder strap pocket
I don’t use a hydration bladder, but I still keep the removable sleeve in the pack since it works well for small items on day hikes away from camp.
I also added an optional Outdoor Vitals shoulder strap pocket and use it constantly for quick phone access. I’ve used a lot of shoulder strap pockets, and I prefer the stretchy mesh and tighter cinch on this one compared to others.
Internal organization
With this pack, I can fit everything that I used to fit inside an Osprey Aura 65-liter pack, without carrying gear on the top or bottom of the pack.
My packing system is pretty consistent: at the bottom, I use a waterproof pack liner for my quilt, pillow, down jacket, and clothing. That gets compressed and fills the lower portion of the pack well. Next comes my food bag, then tent, pad, and cook kit. On top of that go smaller essentials like my first aid kit, toiletries, electronics, and ditty bag. Anything I might need quickly, like a rain jacket or mid-layer, stays near the top.
Comfort
Comfort is the main reason this pack stands out for me. The curved carbon fiber stays provide enough structure to support weight well, while still allowing some flex with movement. It feels supportive without being overly rigid.
The foam on the shoulder straps, hip belt, and back panel also makes a noticeable difference. It’s softer and more substantial than many ultralight packs I’ve used, which helps reduce pressure points without feeling bulky. The cutouts also help with breathability on warmer hikes.
Load lifters help pull the pack closer to my body and shift more weight onto my hips, which improves stability and reduces shoulder fatigue.
Fit
The fit on the Carbon Evo is more adjustable than most ultralight packs I’ve used. The pack comes in multiple torso sizes, and the hip belt is separately sized. I use a short torso pack with a medium hip belt. I initially tried the small, but it felt too tight and had very little adjustment range.
The hip belt is removable and adjustable with hook-and-loop placement, which helps fine-tune where it sits. Raising it slightly higher made a noticeable difference in reducing pressure on my lower back. The dual tightening system also helps create a secure fit without constant readjustment.
My experience
On my first backpacking trip with this pack, I carried a 21-pound load, and it immediately felt better than other ultralight packs I’ve used. The carry felt stable and controlled right away. Most ultralight packs I’ve tried have created pressure points or a barrelling effect that made them uncomfortable over time. The Carbon Evo has been different — it feels more consistent and supportive from the start of a hike to the end.
Compared to my heavier Osprey Aura LT pack, the Carbon Evo feels much more minimal while hiking. The Osprey wraps more around the body and has a raised back panel, while this pack sits closer and feels more direct against the back. Even with that closer contact, it still feels stable on uneven terrain.
I also really like how small it is when empty. I usually keep my pack inside my tent at night, and this one takes up very little space, which makes it easier to manage in a smaller shelter setup.
Overall, this will be my go-to backpack because it gives me the lower weight I want without giving up the comfort and support I need.
