At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.
Good scores are more common than bad, because fortunately good products are more common than bad.
Vaude's Isny II daypack is an eco-friendly option with a spacious main compartment and a roll-top closure to keep everything perfectly dry inside. It's a bit light on features though – it only comes with two pockets and an unpadded sleeve for a laptop - and there are no zipped compartments.
Made in Germany, this waterproof 20L backpack has a height-adjustable roll lid that can add another 8L to its large main compartment.
Its felt-padded shoulder straps are absolutely delightful. Vaude says the fibres are made from cow's milk that can no longer be sold for drinking – it's processed with wool to produce a felt composite. It's silky soft, which is particularly good with sleeveless tops.
Comfort would be higher still with a padded back and a chest strap for reducing pressure on the shoulders, but unfortunately both are absent.
This backpack is PVC-free, and uses Vaude's water-repellent Eco Finish. It beads water without using environmentally harmful fluorocarbons, and effectively held off heavy downpours during testing – it's great to see an eco alternative without any performance compromise.
There's not much else on the outside, bar two handy holes for hooking rear lights on and a reflective logo. It looks smart, but it's lacking some practical essentials: there are no easy-access zipped pockets for essentials such as phones, nor a water bottle holder or a handle.
The main compartment is large, which means it's easy to load up bulkier essentials. There's also a key holder, a padded phone pocket, another slightly wider pocket and a sleeve that fits a 15inch laptop. This sleeve only rises two thirds of the way up and isn't padded, though.
While the laptop is held securely enough, the sleeve doesn't protect it from your other stuff, and the pocket's too slim to take a computer in its own sleeve. Absent all these extra touches, it's no surprise the bag weighs in at a rather light 580g.
It does allow you to pack it full without it becoming too heavy, but at the same time the lack of chest strap and back padding reduces comfort over longer periods. For short commutes, it's effective at carrying the essentials and keeping them dry.
At £85, the Isny II is expensive for a bag with so few pockets and features. For me, the eco credentials add value, though, and it is reassuring knowing it's backed by Vaude's five-year guarantee against defects.
That said, the 100% Transit Backpack is cheaper at £69.99 and has 10 pockets for a proper organised commuter system. It doesn't come with a waterproof cover, however, and also lacks a supportive chest strap.
The Merida Fifteen II backpack is even cheaper at £49.99, and impresses with its stability on the bike. It's also lighter than the Isny II, but it's not waterproof.
For a simple waterproof backpack, though, the Vaude Isny II is effective, stylish and comfortable.
Minimalistic, eco-friendly waterproof pack with comfy felt straps, but lacking commuter-friendly features

Tell us what the product is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Vaude says: "This backpack with a height-adjustable roll lid comes from the VAUDE Manufaktur and is a highlight for purists. It is minimalistic, designed with clarity and uses a felt made from milk fiber (Q-milk) in the shoulder straps."
