The runbox was a perfect fit to my frame of 1.6m and 56kg, with all the strap pulled to the maximum. The bouncing was minimal and I run it for at least 4 times of around 8km. The bag is waterproof and the interior of the bag was dry after the run. My laptop seems perfectly fine. The amount of bouncing is equivalent to normal walking. I can say it is a well invested purchase since I could now continue to commute from office to home with my laptop now.

I purchased the 18L size in white and am really happy with it. The design is functional and modern (pockets included inside fit my laptop, kindle, and notebook). The customers’ comfort was also obviously a top priority in the design of this bag. Even when I carry my laptop, the bag feels incredibly light.

I this for the daily commute on my Vespa - I Fits in my shoulder bag and carry my work suit and shirt wrinkle free. Also use in my business carry on luggage. I recommend the product.

I have used the first generation Backback Lite for over a year and been very happy. The 2.0 Pro is a clear refinement and has quickly become my daily goto bag. Light and stable enough for long run commutes and spacey enough for cycle commuting when you want to bring extra lunch/clothes.
I strongly recommend to get the space bag which really makes this into the ultimate commuter backpack.

J'utilise mon sac presque tous les jours depuis l'achat, dont plusieurs fois pour revenir du travail à la course et je suis très satisfait. Il est très bien conçu, robuste et très stable lorsque je suis en mouvement. Il a un bonne capacité de stockage, quoique j'aurais aimé un "shoebag" un peu plus gros. Je recommande ce sac à tous les gens qui utilise la course pour se rendre au travail.

I’ve tested the product for 2 weeks now and, if it took me a few days to adjust my settings, I am clearly in love with it !
I would recommand it to anyone who need something professional and sport compatible.
The extension bag is clearly a plus that I need to get to complete the pack thought.

Been using this everyday since i got them month ago. (Even though I’m not really running to work, mostly walking) I can fit anything i need for the day (work and after work training gear). Neat and simple design. Love it.

I've had my grey spin bag 30L for a few days now and I love it!
It has all the space I could need without being too bulky - I fit climbing equipment, workout clothes, lunch, snacks and my work laptop.
The laptop pocket is great for getting my laptop out without having to dig through all the other stuff. Also, the bag looks very sleek and professional!

I have tried many bags but no one as good as this bag. I Will also give the suport group a star as they answered all my questions fast and kindly.

I am so happy with my Spin Bag 18L that I bought last summer. I use it everyday at work but have also been taking it kayaking and canoeing, it's perfect for water sports because it's waterproof :) But mainly love the ergonomics, it's just perfect!

Love the backpack and have been using it ever since ... it’s definitely durable and spacious and looks good

The one criticism is that it could do an an extra zipped compartment inside for loose stuff

The order process was great. But not to forget the countries customs fees??
The bag was the greatest success and very much appreciated

I purchased both size bags and found them far more durable than any product. Years of traveling checked at airports, hiking, bike touring!!! After almost a year and a serious bicycle accident I had a small hole where most materials would she'd against the pavement. I patched it with a tough reflective sticker and it's as good as new. All I know is that it's the only back packs I'll ever need, recommend and ever purchase again.

Best back no jiggle jaggle no rubbing it just clings to back brilliant

I have tried several professional backpacks both for bicycling and running to work. I frequently have to carry my laptop back and forth and always a change of clothes, and a 10 k run with a backpack that is moving around a lot is simply too uncomfortable. Having just received my new Backpack Pro 2.0 I have run 40 k in 7 days, first with just a simple change of clothes but the last runs with a laptop as well. Works beautifully and so much more "stuck" to my back. Can't say anything about longevity yet of course, but if it holds up it is definitely a winner and good running companion.

They have really done their homework well - this is a great running backpack!

I was sceptical at first, but this really works. It has changed the way I commute - I can now easily run to/from work and carry my work outfits wrinkle free! It’s also very useful for those travelling on business who want wrinkle free shirts and suits. I would definitely recommend.

Bag is spacious: fits all I need for gym (a towel, and sportswear including shoes). It has nice set of compartments. I am satisfied with the quality and the looks of it. The only downside is that the center of mass of the bag is quite far from my back which makes it move a bit more than I would like. Otherwise - great so far.

Perfect tools for traveling efficiently. Keeps clothes ready to go as soon as you unpack them!

Good service and quality of goods.

I will be travelling Europe by train with a large duffle bag on wheels. These garment organizers will keep my dresses and blouses protected from being crushed & wrinkle free!
I will be getting some for my husband too.
Very happy with my purchase!

Origami has been for ages the best way to pack and save space. In my case you can see that I'm traveling with a lot of things, it's a 5 day trip between Prague and Helsinki and I managed to carry everything that I need. The photo is missing my second par of shoes. I highly recommend this, if you are worried about carrying your working clothes and avoid wrinkles. Thanks guys for this amazing add-on to my backpack!

I have used the large and small Origami Organizers and their firm shell protects the contents well. Anything that is crushable and deserves a greater degree of support will benefit. A simple solution that compliments soft packing cubes when protection is more important.

Just returned from 9 days international travel combining work and leisure. Origami Organizer kept my important garments protected and as I packed them. A great compliment to my usual soft packing cubes which still have a place for unimportant gear.

I've been run commuting with this backpack for the last couple of months, and I really like it! As advertised, it is very stable and does not bounce up and down or rotate from side to side when the straps are tightened correctly. The hardshell case seems essentially waterproof, as my clothes inside were completely dry after running home from the office in the pouring rain for about 50 minutes. I also really like the pockets in front for my wallet, phone, and keys, as these pockets prevent me from having to fumble around in the backpack to access these items, as was the case for my old backpack.

The space inside is adequate for most of my runs. For a longer distance 11 mile run to a morning meeting out in the suburbs the other day, for example, I was able to fit a folded pair of dress pants, a collared shirt, sweater, underclothes, towel, washcloth, and folded duffel bag for dirty clothes inside, and used the shoe bag attachment to carry toiletries to use at the office building's shower and a bottle of orange juice for the run. For my typical 6 mile commute to my office building, however, I don't need to use the shoe bag attachment, but I'd recommend getting it to have the added space for longer runs, or when running to other offices where you don't have a stash of toiletries on hand.

This version of the backpack doesn't really have an attachment for a water bottle, but I understand an attachment is being added for the upcoming 2.0 version. Also, you can expect the cool IAMRUNBOX logo on the back to start rubbing off if you carry the shoe bag for a significant distance. These are minor complaints though and if you are a run commuter, I think you'll really like the backpack.

I'm a backpack junky.
I love them and I have way too many of them.
The last great purchase was the SABLE RUCKSACK - OLIVE from JustPorter for $200. I love it until I got my SpingBag in Orange.
Main Points:
LIGHTWEIGHT!!!! it's super ultralight, compared to the Sable which is 500grams heavier.
Ultra-Comfortable: This is a big point. Some of the ransack that I tried before they were ok as the shape of the backpack, but the SpinBag it's amazing. I just love how much I can carry and feel that it's hugging me.

I will write a full review in my website https://fmillan.com/spinbag

I am so happy that I picked the 30L bag (was first considering the smaller bag). I think it is a really versatile yet really stylish bag and so I use it everyday for everything between flying to business meetings, day- and weekend trips, commuting to work (by bike), bringing gym gear for after work workout and more...

I've used it every day since I got it and still no real signs of wear and tear, this bag will be with me for a long time - a big thanks for a great product to the team at IAMRUNBOX!

I was looking for a sleek looking backpack, which I can wear with a suit and still look good meeting clients. Another important factor for me was sustainability and ethical production. This product has it all and more. IAMRUNBOX has surpassed my expectations and even when I needed to call the customer service, they have been super fast and helpful! 100% recommend!

I was using this bagpack for commute run to the office. I probably run over 1000K with it. It is nice and durable. Only one side effect is the zipper. My started to worn out recently. Everything else is perfect. Because of the zipper, I would give it 4 starts out of 5. However it is only in it's class and serves well. So 5 stars it is!

I have to travel often.This is my most loved equipment.Shirts arrive wrinkle free...so nice...👍👍👍👍👍👍Looking forward to ...may be....a tie case?

Used it for my daily commutes a few months now. Love the bag, ergonomics and functionality. Clean design and also perfect for a city use.
Really like the quality and materials used in the bag. Also nice to have an option to remove waist straps as normally I don't need it.
