F4 Crossbody Sling Bag for Men: Ultra-Slim 30 mm to 50 mm

I’m glad I did the research I did before buying this bag. Great size, fits my body well, aged nicely so far, the retractable keychain is very convenient. Everything about it does the job. I’ve used this thing for travels (flights and by car), work as a driver, and casually. I’ve thrown it around a few times with no issues. The clip to unstrap is well made. No need to worry about it coming off accidentally. It has never happened to me. Lastly, very minimal and stylish. Overall just a solid bag. Definitely keeping an eye on this company for more of their products because the passion and care is there. Thank you. Make sure it suits your needs and buy it.

Where do I start from with the quality of this bag? Top notch. Excellently designed!!

I recently got the NIID-FINO F4 Sling Bag, and it's been a game changer for my daily outings. This bag is incredibly light, which makes it perfect for someone who enjoys minimalism and hates feeling weighed down. I love the versatility—it can be worn as a crossbody, fanny pack, or sling bag, depending on my mood or activity. The sleek design goes with pretty much anything in my wardrobe; whether I'm heading to the office or just exploring the city. It's not just stylish but also surprisingly spacious—I can fit all my essentials without any hassle. Overall, it's become an essential part of my daily routine!

I only have 2 things. I did my research on what I wanted. Came across F4. Watched the videos and was all in. Ordered it. Was hoping everything was in the bag like the video. 1: I was a little disappointed that I had this 2 white specs. I know it's petty, but I was hoping to have it perfect like the video. But then again, not too big a deal. And the 2nd thing was there was no face mask cover. Other than that, love the bag. Material is premium. High quality material. Durable indeed. Quick snap is super easy, accessible and feels strong. Many pockets inside to fit your things. Keychain accessory is clever and convenient. High recommend this bag. A must have!

I’ve been looking for a new crossbody sling for a while, and after trying several others, I stumbled upon the NIID brand, and purchased 3 of their crossbody bags before I settled on this one, and it’s been my go to sling ever since! Pros -I absolutely love the slim profile! It looks sleek, and stays close to my body even when expanded -I love that it has an expansion zipper, so I can carry more without the sling looking too bulky. -So many pockets! There’s a felt lined pocket in the front, two mesh pockets in the main part of the bag along with a zippered pocket. There’s also a magnetic pocket on the back that’s big enough to hold a smart phone or wallet. -The retractable key chain is a life saver! I hate having to root around in my bag for my keys or need to unclip them in order to unlock my door because then I tend to set them down somewhere and waste time trying to find my keys. Having a retractable key chain should be standard for any sling bag, and I’m glad NIID includes one in all their bags. -I love the sleek design of this bag; it goes with everything and looks professional too! -This bag seems to be water resistant (which I really like), and when I got caught in some light rain, everything stayed dry inside, but I’m not sure if it would withstand a torrential downpour. However, there are a few things that prevent me from giving it five stars. Cons: -None of the pockets on this bag are big enough to hold a tablet. The fleece lined pocket on the front is just big enough to hold a Kindle Paper White (without a case), so anything longer than 7 inches or wider that 4.5 inches won’t fit. -The material looks sleek and feels premium inside and out, but after 4 months of use, you can see that 2 tiny holes/tears have appeared along with visible scratches on the bag and handle, so I question its durability long term. I haven’t contacted customer service yet, but I’ll update my review accordingly once I do. -The full price is a little steep for a bag this size since I question its durability, but I definitely think it’s worth it when they offer a discount. -I wish the bag was a little deeper on one side, so I could carry a water bottle as well. While I love the shape of this bag, the size is just a little too small to use as an EDC for longer commutes, but perfect for travel with its anti-theft features. Overall, I’m very pleased with this bag and the NIID brand as a whole. If you’re traveling or looking for a slim and minimalist EDC, then this bag is a must have! However, if you’re looking for a bag for commuting or to carry larger tablets/electronics, then this is definitely NOT the bag for you; however, I still think NIID bags are an excellent choice as a whole for an EDC (especially if they improve their sizing and durability in future models).

I use it for short trip (i.e. going to groceries or other short errands). This bag is very functional and a very good quality made.

I highly recommend this sling bag. It is so comfortable, easy to adjust and smooth. It is totally worth the price.

I like the fit and all the compartments. I bought it for a trip I am taking. Hope it fends off pick pockets. Will report when I get back

デザインが良く、格好良いです。 さわり心地はサラサラです。 メインのポケットは磁石で閉じられるようになっており、楽です。スマホが入れられる小さいポケットがあるのもポイントが高いです。 素材がポリウレタンとポリエステルということで、特にポリウレタンの寿命は加水分解が進みやすく2から3年くらいとされているため、10年先まで使えるかというと難しいかもしれません。 収納量としては見た目通りそこまで大きくはなく、拡げた状態で500mlペットボトルを1本入れてあと小物といったところです。 左右非対称の形なので左肩に掛ける形となります。

The bag is made well, great attention to detail. However, for me being 5'8" the bag was a bit big and did not lay well on my back. The fact that I am left handed the bag was backwards and did not switch for the same functionality as for a right handed person. The bag material is very shiny and look more like a purse than a bag.

I just didnt like the fact that i didn't get the bag for mask with velcro
