Reviews

Absolute game-changer for the backcountry!

"The integration of the bino harness and hydration set is seamless. The harness keeps my optics completely secure, protected, and easily accessible when seconds count, while the hydration setup rides comfortably. The build quality is rugged enough to handle heavy brush and tough weather. Another stellar piece of gear from KUIU. Highly recommend to any serious hunter!"

— Tony B. (5/5)

Great Harness

"Awesome, I hunted 5 days for antelope, for the first time with Bow and Arrow! The harness was great! I was using the medium with 10 x 50 binoculars, I walked miles every day wearing the harness. Each little compartment is great for holding knife on one side, wind on the other, and then cell phone in the back! The top closing system is great too highly recommend. Thank you. Kuiu!"

— Mark H. (5/5)

Exceeded expectations!

"Great system! They have covered every angle! As a type 1 diabetic I have lots of room for sugar or granola bars in case of lows, lots of room for my phone so that I can navigate with my gps and see where my blood sugars are and the bear spray holder is such an asset since the majority of my hunting is done in bear country! Thank you! Please continue making great, quality products!"

— Darrell D. (5/5)

Combo Bino Harness

"Great combination! I like how the side pockets connect, with a double connection. I needed the bigger size for my new binoculars, and this is perfect. I also like the hydration system integration. As always, KUIU is top quality materials and finish."

— Scott D. (5/5)

Great product

"This is the second one I’ve purchased. My PH in South Africa loved it so much I decided to gift it to him. I did shop around again before purchasing again and did not find another comparable product that checks all the boxes."

— Danny T. (5/5)

Good fit, small pockets

"The harness fits well to the chest and i like the adjustment straps. The rangefinder pouch attaches well. My biggest complaints are that the side pockets and front zipper pocket are so small and tight you can’t fit hardly anything in them. Also I wish the bino compartment lid would fold down or off the way better. Other than that, nice chest rig."

— John H. (4/5)

Awesome

"As with all Kuiu products, fit,form, function is outstanding. One minor complaint, the side pocket is really tight, wind checker doesn't go in with one hand, have to pull open with one hand and place bottle with other, juggling archery equipment, maybe make your own wind check bottle to custom fit"

— Ted J. (5/5)

Much better than my other brand.

"I would have give 5 stars if the closing was easier in the end of closing. Sometimes I need 2 hands to really shut the lid properly"

— Lars-Olov L. (4/5)

Pro g3 bino harness

"This bino harness is great. I used to always just use the stretchy type bino harnesses because I thought systems like the pro g3 seamed to bulky. The pro g3 keeps my binos, phone, wind checker, folder knife, and range finder (with the extra case) all right on my chest. I really like that it doesn’t flop around or move when hiking and crawling under things. The pockets are kinda tight but that also keeps anything in them from moving. Easy one hand opening and closing once you get used to it. Very well thought out piece of gear. Only complaint is the metal piece (or whatever it is) that keeps the shape on the top of the back piece ( chest side) is starting to show wear at both ends of it. It looks like it is going to wear through the fabric. I’ve had the harness for a week and a half and used it 4 days elk hunting."

— Matthew B. (5/5)

Doesn't fit some binoculars

"This has been frustrating regarding the attachment to the binocs. The small webbing doesn't fit my Leupold binocs, since the hardware on the binocs is very low profile, the doubled up part of the webbing doesn't slide through. Not so much about your product I guess, just frustrating."

Q&A

Will the Bino straps be thin enough to fit into the attachments on a Swarovski CL POCKET 10?
They will likely still work as they are thin straps
Hi will my Leica 15x56 fit inside the xl. it is 21,5 cm tall
They will be a bit tall for our XL harness. It might work, but will not be the most ideal option as the lid might not fully seal over the back of the harness
Do the straps adjust enough for a petite frame? I am 5"1" 110lbs. I am concerned it will hang at my belly and isnt adjustable enough to sit at my chest.
While you are on the lower end of the size range, it likely will still work for you if you shorten the straps all the way. If it does not work for you, we do offer a 30 day return/ exchange window
Will Leupold 15x56 fit
They are a little taller than our XL harness. They will fit inside, but you might have difficulties fully closing the lid
Hi. I am running a leica 10x42 grooved pro range finder bino. It’s a few years old and a bit larger than most 10x42’s. Which size of bino harness do you recommend?
You will want to use the XL size for your binos
