Frame for Wisport Sparrow II 30 l backpacks

I recommend buying this additionally. I wonder why the manufacturer doesn’t include it in the set. Reinforcing a backpack of such capacity is necessary—maybe the manufacturer wanted to keep to the specified weight. I don’t think it’s about costs, considering the price of these backpacks.

It's just a regular bar, nothing to elaborate on—it does its job. In my opinion, it's a necessary addition for the Sparrow backpack. It's a pity it's not included from the start.

If you have a Sparrow, don't hesitate – the difference is huge. It’s a pity it’s not part of the set, but the cost is small. I use it in my BOB and can't imagine being without this back support. A necessity.

A great add-on for people with Wisport backpacks – it stabilizes the back, making it easier to carry and adjust the backpack. Doesn't deform the back even when fully loaded.

The frame works flawlessly. Even with a heavily loaded backpack, the back panel remains stiff, which improves wearing comfort. It is very light and well-fitted. I think it should be included with the backpack. I recommend it.

A practical and essential stiffening element for a backpack. Light, cheap, and significantly improves comfort under heavy loads. Installation may take a moment – the pocket is tight, but that's a plus. Once installed, it serves for a long time. It should be standard in every backpack.

Very nice for me. I heard sometimes it needs to be filed, but my piece was smooth and fit the pocket with no problem. Good size, once the pocket is closed it isn't visible.

The frame for the Wisport Sparrow II 30 l backpack does its job – significantly improves comfort during long marches with a heavy backpack. You just need to adjust its length, as it is a bit too long. It's also worth filing away the sharp edges.

Useful when the backpack is loaded with something heavy. You can manage without it, but it would be good if such an element was included. Unfortunately, it's quite sharp and difficult to insert, but with a bit of force, it's possible.

Nothing to elaborate on. It's a frame like any other—well made, does its job, and I think it's worth buying with the backpack. It's also quite light.

The military backpack stiffener is an extremely practical solution – increases comfort and helps better organize the interior. Thanks to it, the backpack is more stable and the luggage doesn't move around. Highly recommended.

Highly recommend – great quality. You need to adjust the length for the Sparrow II, but after installation, the backpack is much stiffer.

I think it's a must-have accessory for the Wisport Sparrow II 30L backpack. I used it for a while without it, but after installing it, I can't imagine using the backpack without the frame.

After shortening and properly securing the edge with tape, you can easily use it with the Wisport 20. The material seems durable and sufficient for stiffening the back part of the backpack.

I am somewhat disappointed, because although the product is designated for the given model, it turned out to be too long, I had to shorten it by a few centimeters. The ends are not protected with rubber, so they can damage the dedicated pocket. I would be willing to pay extra for better workmanship.
