Built for moving fast and covering long distances, the Beta Light UL 45 is the ultimate blend of durability, lightweight construction, and load-carrying comfort.

We partnered with Challenge Sailcloth to bring their Ultra 200 body fabric to our Beta Light series to create one of the lightest yet most durable packs on the trail. This durable fabric, combined with taped seams and a roll-top closure, makes the pack weatherproof and able to stand up to day-in-day-out use. A simple, Power Mesh stretch pocket and two side pockets provide plenty of external storage options, while the pack’s running-vest-inspired shoulder strap harness system provides support and comfort with additional snack pockets and water bottle storage options. A removable hip belt, lightweight aluminum frame, and removable foam back panel provide options for reducing weight even more.

Impressive backpack!

"I had a chance to do our first overnighter with this backpack. My pack with 2L Water weighed just 23 lbs. I notice that after a few minutes, the sensation of wearing the pack fades into the background and doesn't feel like a burden. I appreciate the mesh pockets on the strap for carrying items like my mobile phone, a monocular and multitool. One thing I struggle with is reaching the water bottles on the side—it seems like they're just a bit to far back to reach on my own. Other than that, great first impressions."

Minimal but functional

"Love this pack. Light, comfortable, just enough pockets and spaces to keep what you need handy."

— Brian H. (5/5)

I've spent a lot of

"I've spent a lot of time moving through the mountains with nothing more than a running vest, often covering 20+ miles of ridges and peaks in a day, so I’ve been hesitant to purchase a new overnight pack. I seriously considered the Hyperlite, but after trying both, I found the Black Diamond Beta Light 45 to be significantly more comfortable. I recently used it on a quick overnight in the Cascades, and it exceeded my expectations. It's lightweight, moved naturally with my body, and never felt cumbersome, even on more technical terrain. The pack carried everything I needed for an efficient overnight without sacrificing mobility, which was exactly what I was looking for. If you're someone who likes to move fast in the mountains but occasionally stretches into overnight adventures, this pack strikes a great balance between weight, comfort, and capacity. So far, I'm really impressed."

Excellent Pack for a 3 Day Trip

"My first sojourn with the Beta Light 45 on a 3 day trip in Bears Ears was a success! The pack is superlight, yet, appears to be very durable. It didn't seem overloaded despite the fact that I filled it to capacity, and I had a few things attached to the outside (I'd recommend adding the BetaLite Satellite bag). The waist belt could be a little beefier but otherwise no complaints!"

Thru-hikers Dream

"Did the Colorado Trail wearing this pack ranging from 17-32lbs and it performed flawlessly. Running vest style straps are super functional. Body and frame hold good structure to avoid the lumpy canon ball effect of some ultralight packs. Side pockets are spacious but hold stuff in well. Absolutely my go to pack now."

— Mitch (5/5)

Unique product offering

"Purchased this because not many backpacks have vest style shoulder straps in ultralight fabrics. This pack is well made, and well seam sealed. Ultra is a game changer for its abrasion and water resistance. 5 foot 7 and a medium fits well. Only negative for me was that it has two vertical aluminum stays but no horizontal cross member . So overfilled it can be prone to barreling but for a very big load, I wouldn’t use an ultra light backpack anyway. Also wish the top buckles could be rolled and buckled to the sides instead of together on top. So as to make a more sleek profile for one bag travel without getting attention from the airline."

Perfect for my needs.

"Purchase this for a recent hike on the Peaks of the Balkans trail. It was the perfect size for holding everything I needed to go from hut to hut. We did not need sleeping bags or tents, but the pack would’ve handled those easily. Very comfortable harness and supportive waist belt. Convenient pockets and the stuff pockets came in handy for water and snacks and rain gear for quick access."

— Bruce J. (5/5)

Great lightweight pack but. . . .

"Overall like the pack and have used it for multiple 3-5 day trips. Rides well and as expected when you cut weight you loose some features. It cannot be overloaded or it will carry like a potato sack. The add on buckle on pocket is pretty much essential and is a great addition. Biggest issue for me is with the anti-sway straps at the shoulders. The narrow webbing slips through the buckles and does not hold, requiring constant adjustment. Also the amount of adjustment on the straps is not enough. I need to be able to pull the straps tighter and they are out of webbing. Guess I am going to have to pull out the sewing machine and get it the way I need it. Or maybe BD will come through. . . . . . . ."

Stylish and functional

"Wow, what a pack! I love this pack, it is light, comfortable and durable. I’m 5ft2 and got a size small which fits great. The 45 litres is perfect for multi day trips even with a tent and the front pocket is amazing! I can fit so much stuff in there it’s insane and I’m really impressed with how well the mesh has held up. This pack has been around sharp rock, ice, scree and sharp vegetation and so far only the tiniest snags on the mesh but no holes! I love the big open space, it’s great for organising where my stuff goes in their various dry bags and my stove fits in nicely. The tent poles go great down the side of the pack, along with my hiking poles. I haven’t used the reservoir sleeve for that intention yet but it serves really well as a pocket for dehydrated meals, spork and snacks etc. The only thing that I don’t like about this pack is that I find the weight loading straps tend to slip so I have to check them and tighten; this may be because they are quite thin straps but otherwise this pack is great and I love it for it’s intended purpose. The vest style pockets are amazing and fit all the essentials and I really like that little rubber loop on the shoulders, I use it to clip my Garmin InReach mini and then wedge it in the pocket so it doesn’t bounce around- perfect spot for it! I also find the zips on the hip pockets are smooth and really easy to open and close. I love this pack so much it only took one conversation to convince my work colleague to buy one! I also love the colour and look of this pack!"
