Zefal Z Dry Pack L-DS



Light and pretty water-resistant saddle pack at a decent price

At 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.

A saddle pack is a useful means of carrying the things you need with you on a ride – you can just leave it in place, knowing that you've got a puncture kit, spare tube and multi-tool with you. If you're going to leave it there, it's a good idea to have one that'll keep the water out, or you might find that some things start to go rusty. The Dry Pack from Zefal does a good job of keeping its contents dry and is both lightweight and fairly inexpensive.

The material used for the body of the Dry Pack is a thermoplastic polyurethane, here in the form of a relatively lightweight plastic fabric which is waterproof. It isn't stitched – the seams are joined using ultrasonic welding, meaning they too are waterproof, and the zip is a water-resistant one too.

It fixes to your bike via the simple means of Velcro straps – one around the seatpost and a couple that thread through the saddle rails.

Some saddle packs have more sophisticated mounting systems, with brackets that clamp to the saddle and a quick clip to fit and remove the pack. In my experience this can work well, as long as your saddle position lets it fit. That's not going to be an issue here – the straps worked on all my bikes and those I've tested this year, including a Ritchey saddle with the Vector Evo rail system. The strap that goes around the seatpost is long enough for a 31mm diameter post, but won't fit anything larger, such as an aero post.

If your bike has a posh carbon-railed saddle then don't worry – the straps and the bag itself don't have any hard bits to damage either the saddle or the seatpost. If the bag isn't full, then by tightening the Velcro straps on the side you can cinch the bag up so it isn't too rattly. Unfortunately, if you do that then the ends of the Velcro straps finish up right inside the saddle, making it quite fiddly to get to them for removal.

In terms of sizing, Zefal calls this an L, and it's a decent size, if not the largest on the market. I had no difficulty getting a couple of tubes, puncture kit, CO2 inflator and multi-tool in there, with room for some emergency sweets too. The bag also tapers in width towards the front, and even when full to capacity it never interfered with my thighs while I was pedalling.

A welcome touch is the consideration given to night-time visibility. On the sides and up the rear of the bag are decent-sized reflective patches, and there's a loop on the rear to which you can attach a light. The fabric isn't that stiff, though, so the pack needs to be well-filled to prevent the light hanging downwards and directing its beam at your rear tyre. To be honest, I didn't really use the loop because it's pretty easy to fit a light to the seatpost below the saddle pack, but it could be useful if you had a clip-mounted light.

At 117g, the Dry Pack is impressively light for its size. This may not be your prime consideration – weight weenies are probably less likely to want to fit anything but a tiny saddle pack to their best bikes – but it's lighter than some similarly-sized packs by the equivalent of an inner tube.

Unfortunately, the first Dry Pack I was testing suffered a problem with one of the welded seams, which started to peel apart after I'd only used it a dozen times or so, making it suddenly very water-permeable. Panel shaping is fairly simple, with the edges of the rear panel looking a little bit vulnerable. A replacement was sent out, which I loaded up to the max, with my heaviest multi-tool and as many inner tubes as I could fit in there. That's been going strong for a few thousand km, suggesting it was an isolated problem rather than a more serious design flaw.

There are various other water-resistant saddle packs on the market, from the likes of Ortlieb, Topeak, Giant and Altura. All use welded seams and most of them have a roll-top closure rather than a zip. I didn't really have any problem with the zipped closure here, in terms of water ingress, and there's not a lot between the two styles in terms of ease of access. The price of this pack from Zefal is competitive with similar packs, and less than an Ortlieb, whose bike bags are pretty much bombproof but priced accordingly.

Rate the product for quality of construction:

The focus is obviously on water-resistance and low weight rather than something bombproof that you can pass down to your kids. On the first one, the seams started to come apart but its replacement hasn't suffered from this.

Rate the product for performance:

Pretty decent. Keeps its contents pretty much dry, doesn't swing around too much. Good reflectives and a light loop are welcome additions.

Rate the product for durability:

I had two. The first one lasted a couple of months before a seam started to peel apart. I've loaded up the second one and exposed it to the worst of the autumnal conditions and it has thus far not followed suit. I wonder whether the welded seams are maybe not hyper-durable, and the edges of the rear panel are a vulnerable point, but I might be proved wrong!

Rate the product for weight (if applicable)

Particularly light for its size.

Tell us how the product performed overall when used for its designed purpose

I was pretty disappointed by the short life span of the original test bag, but its replacement has fared much better. It has a decent capacity and keeps its contents pretty much dry. Velcro straps aren't a sophisticated fitting system but they work on just about any saddle and they don't weigh much.
