I have been looking for this product for ages - everywhere in the whole entire world but couldn't find it - until when I by accident found it here on Amazon (the US site)! That was the BEST decision of my life!VentaPak is just so unique and functional that it is worth every single dollar you are paying for this product! Remember that you have only one back and you don't want to destroy your back with bad posture cause fixing your back when it is already broken is super difficult to cure, that it's actually better to prevent it from happening from the first place.And who wants to walk around with sweaty sticky back on the same time? Noone!Does this product live up to the hype? Hell yeah, it definitely does! On the contrary, I'm actually positively shocked over the result. Even had to order it from other side of the world with customs and import etc... but still worth it. Wish that this product is coming to Europe. Maybe eventually?The whole entire frame is that sturdy and stable that it could even handle my HUUGE back with full of loads without any problems. Not even a single bend or any breakage at all. This thing is made to sustain huge amount of load, I'm sure I can use this for years without a hiccup.Is it comfortable to use? Oh yes! It feels so much better to use this one than without, that much I can tell you! The shape and forms were perfect and it fits all the rucksacks I have tried so far.I paired with all from street rucksacks to hiking rucksacks to hydration packs, everything fits due to the simplicity of the attachment device.Is it lightweight? Very much!Any cons so far? Well, unless you need to fold your rucksacks to save space, then I don't see any reasons why you shouldn't buy this ventilation and good-posture-for-your-back product!I just wish I knew about this product earlier or it was produced earlier cause so many years I have been suffering with both bad back posture and sweaty backs that much that I sometimes hated to wear rucksacks altogether but this VentPak product is a GAME CHANGER! That's for sure!And another very positive thing about this product is that the seller and producer to this one was very keen on helping me with answering questions and giving me advice, assisting etc. Seems like they really care about this product and how to develop it to become better and better. That is something I very rarely see in other companies. So thumbs up for this great service!In conclusion, TL;DR: A must buy product and totally recommended! That good product that I actually want to buy one more extra for my fiancee as well.

    5.0 out of 5 stars I'm beating the Florida Heat with VentaPak
    Reviewed in the United States on January 23, 2024
    Size: LargeVerified Purchase
    I recently purchased the VentaPak, and I couldn't be happier with this fantastic product! As a tennis enthusiast living in hot and humid Florida, I've been searching for a solution to keep my tennis bag off my back while biking to the court, and the VentaPak has exceeded all my expectations.

    The Florida sun and oppressive humidity can make a short bike ride feel like an endurance test, especially when you're carrying a tennis bag/backpack on your back. VentaPak is a game-changer for anyone who uses a backpack and wants to stay comfortable in the heat.

    The VentaPak is incredibly easy to use. The setup took me just a few minutes, and I was ready to go. It securely attaches to my tennis bag (which is essentially a backpack). I love how it keeps my bag elevated and away from my back, allowing for better airflow and preventing that dreaded sweaty feeling on my commute.

    The design is both functional and sturdy. It can accommodate various bag sizes, thanks to its adjustable straps and clips. Plus, the VentaPak doesn't interfere with my biking experience in any way – it doesn't affect my balance or maneuverability.

    What truly makes VentaPak amazing is its ventilation system. Living in Florida, I know how important it is to keep things cool. y tennis bag used to stink from the sweat from my back. The VentaPak's innovative design allows for excellent air circulation around my back and tennis bag, keeping the bag fresher.

    It's clear the VentaPak is built to last. It's made of high-quality materials, and I can tell it's designed to withstand the elements, whether it's the Florida heat or a popup shower.

    In summary, the VentaPak has become an essential part of my tennis routine in Florida. It has made my bike rides to the court more comfortable, allowing me to arrive feeling fresh and ready to play. If you're looking to make an activity with a backpack more enjoyable in hot weather, I recommend the VentaPak.

    3.0 out of 5 stars Well built but not the right solution
    Reviewed in the United States on August 5, 2024
    Size: LargeVerified Purchase
    I live with humidity and even though my backpack has some mesh on the back, I still get super sweaty. I tried to find a solution but initially this thing felt overpriced at $50. Well, when it went on sale for $35, I had to pull the trigger.
    I will say that it's built well enough. I don't expect it to last a decade, but they needed to make it light weight, so I can't really fault it there. Unfortunately, though, it throws off the balance significantly. You can adjust the curvature with some little straps, but whether I made it more shallow or deep it was always the same thing. By trying to have more weight on my lower back, it ended up pulling my shoulders back. If my backpack was empty, it wouldn't matter, but since I have to carry quite a few things, it ends up feeling like it's constantly pulling me backwards. Maybe it'd be different on a bike, but for me trying to use it walking, it just doesn't work. I don't want to try to jerryrig something, so I'm just going to have to return it and try to find a better solution.

    The product does it's job and keeps your back the same temperature as the rest of your body. No more sweaty back. However, the price is a bit high as it is basically just an office chair backrest with straps added so it can attach to your backpack. You could make your own for about 10 bucks.

    El producto es mejor de lo que pensaba. Me lo recomendó un amigo que lo utiliza para el senderismo. Y en mi caso cuando voy a ferias de cualquier sector ya sea laborar, tiempo libre o otras actividades, llevo siempre una mochila conmigo. Me sorprendió que el hueco que VentaPak deja es el suficiente para que uno no sude mas por la espalda, aparte de caminar y llevarlo mas cómodo. La espalda lo agradece mucho.

    A good inventive way of ensuring ventilation for those of us who get hot and bothered in the summer.
