I own lots of bags! But this bag is the Cadillac! Light as a feather, unbelievable storage space, and extremely convenient! I highly recommend this bag to anyone who rides a bike to the course or even drives. This bag has it all! Don’t have one? Your missing out!

Just played 9 holes with the Back9 Golf Backpack with a full set of clubs. Although I’m probably never going to cycle to the golf course, the bag itself is brilliant in terms of its lightweight design, with lots of pockets, tons of storage and a very well designed stand, but I’d suggest that it works best - if you're carrying – with maybe 10 clubs max, rather than the 14 that I attempted. I played 18 holes the following day when using trolley and it worked perfectly.
All told, a really fun addition to the golf bag market, and a decent option for younger, car-less golfers who live within cycling distance to a driving range, swing studio or golf course.

As a brand-new product, I was expecting a few flaws and problems. After a month of daily use, I haven't found any. I really love my Back9 backpack, and I love how it helps me increase my fitness goals, which is one of the main reasons I'm golfing every day!

Here's the review I posed in the MyGolfSpy forums:
I got mine in May, and so far it's my favorite bag I've owned (which admittedly is only a few).

It's not ultralight, but it's not heavy, and the construction seems very sturdy. I'm not at all worried about it getting flimsy like my 3 lb. bag.

The bag fits very comfortably on my back. I use it a few times per week to ride my ebike to the 3 courses and ranges that are about 5 miles from my house. I can even strap my pull cart to the rear rack of my bike so I can walk the course and not have to carry all 18 holes (working up to that). The unusual squarish-shape still fits very nicely on my push cart and also securely on every golf cart I've strapped it to. The multi-point connections on the bag allow me to configure the shoulder straps different ways, like when I need a single shoulder strap so I can carry my wife's bag on my other shoulder.

The number and size of pockets is just right, allowing me to store everything I need, plus a bit extra. It has all the features I want, like loops to hook brushes, towels, and other accessories, and elastic tee holders too.

I'm really impressed with the construction and stitching. Nothing seems weak or like it might stretch apart, and yeah, it's only been a few weeks, but all the zippers still seem solid.
The stand works well, but if you don't secure the straps, the legs occasionally get stuck on them, which just means I need to lean down and move them out of the way.
Definitely use the wide waist strap like you would on any good backpack, so the weight sits on your hips, not your shoulders. The back pad works very well at both keeping me comfortable and dry. It breathes well, and my back doesn't end up too sweaty.

When I load my clubs the way they recommend, it doesn't feel top-heavy at all, and I can even duck under low trees.

The only "problem" I've found so far is that I don't use the chest-strap at all. I haven't figured out a way to wear it where the chest strap doesn't make it less comfortable. The bag fits much better when I let the shoulder straps sit wide on my shoulders.

I haven't used it on my motorcycle yet, but I've been up to 38 mph on my ebike and it was completely stable and comfortable. Just a tad more wind resistance.

I really love this bag. It's my #1 favorite golf equipment I own because it allows me to increase my exercise, fitness, and eco-friendly climate sustainability. I feel so good finishing my 18 holes with a bike ride home.

The only thing I don't like about this bag is that every time I talk about it I sound like an effing advertisement.

Lightweight, super spacious, big pockets, your clubs don’t bunch up like in other bags. It’s WAY more comfy on the back than I expected. Besides bigger woods, the fact that you can flip every single club around (even Hybrid) and are able to strap the grips down is absolutely genius.
First impressions based off looks, functionality, space and PURPOSE, 9/10.

I’ve had multiple people asking me where I got my bag. It’s extremely comfortable. Storage is light years better than anything I’ve used before. 14 Clubs don’t rattle. Fits perfectly in a cart as well. What more could you ask for? Feels super well made. Would give 6 stars if possible.

I ride 16 kilometers to and back from the course. The two «spikes» on top of the back of the bag work like a jackhammer in my upper back. And yes, i wear it in backpack mode. Really wish you could buy som padding to cover ‘em up.
