Lomo Zephyr Waterproof Panniers
1181g £34.99 (each)
The Lomo Zephyr Waterproof Panniers are capacious, very waterproof and surprisingly versatile panniers with a very favourable price tag. Construction is surprisingly solid and there’s some surprising refinement in the form of a clutch type mounting system that’s operable single handed and a big broad carry strap for convenient lugging off the bike.
​
Pros: Rugged and very nicely designed, easily tuneable, user-friendly mounting system, surprising refinement for the money, highly waterproof, remarkable value for money.
​
Cons: Nothing of note, but die-hard off road tourists might prefer Rixen Kaul hardware.

Specification
This is remarkably high, especially for the price point.

As I said in my introduction, the panniers are singular (Robb at Lomo generously sent us a pair). 24 litres a piece, they’re made of RF welded PVC Tarpaulin. Before we go any further, Radio Frequency (RF) welding is a technique using pressure and electromagnetic energy to fuse two or more items together. All things being equal and in common with other welding processes, this creates a bond stronger than the parent materials. Now, conceptually, a pannier this capacious might have riders of small compact geometry bikes clicking away. Spoiler alert, I’ve had no issues with Ursula and size 9 feet. That said, for reference the Zephyr measure 47cm x35x20 (height, length and width respectively).
​
Internally, there are three pockets built into the interior (rack side) wall for safe keeping of keys, multi tools, wallets and other valuables. Being a waterproof design, it employs a roll top closure and click fix type straps for real hell and high-water protection. What we'd expect in the latter context but again, the detailing is noteworthy, given the price point. Another welcome feature is the large, raised feet at the bottom. Much as their design would suggest, this protects the 500 denier PVC bottom from premature wear caused by the inevitable everyday carelessness.

Mounting hardware 3.5/5

This broadly follows the classic Rixen Kaul pattern, so very secure and familiar to most. It's also, very adjustable and unlike most I've used over the years, tool free. This also allows the panniers to be mounted left, or right sided. Simply, slacken the stabiliser leg's thumbwheel, rotate to the leg to suit and tighten down. to adjust the top rail, flick the bottom catch open and slide along the holes until you reach the desired point. Press down to lock into place. Mounting and removing the bag is slightly unique, so well worth watching their You Tube video Lomo Zephyr Bike Pannier – Grey

It works like a clutch, pull the dedicated nylon strap upward and this will release the sprung catches allowing it to sit, or release from the rack's top rails. You may need to make a shim from old butyl inner tube so it will entertain varying diameters of rack tubing- I had to do so with the Topeak Uni Super Tourist 2.0 but interestingly, not its disc specific sibling. The only slight vulnerability I can see, compared with a more traditional Rixen Kaul type mount, such as that found on this Oxford Aqua Evo is more moving parts but that hasn't been something I've noticed in the real, mixed terrain and often mucky world to date.

Test Bikes/Contexts
Ours arrived at the tail end of a murky, soggy and periodically very icy January, which is arguably ideal for testing the weatherproof prowess of any kit, luggage in particular. Ursula and my fixed gear winter/trainer serve year-round and do the lugging. Fixed is essentially a cyclo cross frameset with track ends and spacing. Ursula is always a good bet given her small compact geometry frameset and relatively short chainstays, perky and prompt but characteristics that potentially create heel clearance hassles, especially with big panniers and size 44 feet. The old girl also sees a lot of action along unmade roads, forest trails, bridleways etc.
Performance 3.75
Having familiarised myself with the quick release mounting system, overall performance has been impressive across the board. Now, though slightly heavier than the Oxford (1185g against 925g) I wasn't particularly conscious of the added heft. Not surprising when you've got a carefully packed 5 kilo cargo en tow perhaps, but also when they’ve been empty and mounted side by side. Waterproofing is, as I expected belt and braces. Three hours through steady, progressively heavier rainfall confirmed that so long as you’d wound the roll top closure down and secured the buckle properly, rain, sleet, mud and slush will just slither away. Contents were bone dry. Much the same story when I’ve ventured off road, or through flooded lanes where the base has been blasted with grotty, silty water.

The welded construction was clearly uniformly good- proved when I whipped ours from the rack and torture tested it for ten minutes with a concentrate jet of garden hose. In terms of lugging, I’ve not gone past seven, maybe eight kilos- big stuff and I’m wheeling out the trailer. Packed sensibly, I’ve been able to cruise along at a decent pace, confident the mounting hardware would do its thing quietly and competently.
Compared with the Oxford Aqua V20 Single Pannier I noted a little more flex, which I feel attributable to the quick release system. However, minor concerns have been unfounded in 500 miles along lumpy lanes and moderate bridlepath, so shouldn’t be an issue mid tour, let alone commuting through the concrete jungle. The PVC is rugged, though still quite supple, so in common with its gravel seat pack nephew, will mould to accommodate bulkier stuff. Day to day, I’ve gone with 2 kilo lock, change of clothes, towels, boots, tools and of course, a few spare tubes for good measure.
I’ve also done top up food shops, mid ride stop-offs to the bottle bank with a cargo of glass- much the same story-although there was a cheery jingle in the latter context (line with a towel and you’ll be fine). The supple fabric will also compress nicely when navigating narrower singletrack with hedges and foliage either side- no issues with anything coming adrift, providing you’ve got the inserts (and where appropriate, inner tube shims) correct on the host rack and aren’t taking foolish risks. Rack design may play a part. However, no heel clearances woes with Ursula.

As with other big panniers, caution is needed when snaking through gaps in traffic-especially when negotiating bigger vehicles, traffic islands and similar hazards, or running a pair. The same goes for navigating domestic doorways but these are all considerations, rather than cons.
Care/Durability 3.75
Extremely low maintenance thus far. I’ve delivered a quick shot of maintenance spray to the sprung mechanism over the past six weeks, given the conditions and my own cleaning efforts. The glossy fabric is low maintenance- a soft brush dipped in a warm sudsy bucket, (or few blasts of degreaser) has shifted most organic grot with minimal effort. Rinse, dry and done. No obvious signs of wear- some trace marks on the anti-scuff bobbles and all the mounting hardware remains in rude health.

Value 4.5/5
£34.99 is equally impressive, especially given the specification. Oxford Aqua V20 Single Pannier is similarly waterproof and feels bombproof. The zippered section built into the fabric’s outer wall makes for easy segregation and is easily accessed wearing midwinter gloves. While less convenient than the Lomo Zephyr’s quick release mount, the Rixen Kaul type feels a little sturdier. However, it’s also £10 dearer, £20 bought as a pair. The Brae Yonder Waterproof Bike Pannier is also 25 litres and features a laptop sleeve. It employs a very similar quick release system and is available in a choice of red, or black and Brae cites will manage a 10-kilo payload. However, even reduced to £49.90, they’re £15 dearer than the Zephyr. Altura Thunderstorm Adventure 25 Cycling Pannier is 25 litres, available in red, or grey and made from Polyester with a TPU coating and features an external zippered pocket. However, these are £56 apiece and we can’t comment on their performance.
Summary
Even taking their price out of the equation, the Lomo Zephyr waterproof paniers are extremely user friendly and dependable. Minor points aside I’ve only noticed them in the most positive sense. On balance, models with Rixen Kaul mounting hardware have a slight edge on the tenacity front and if you’re exclusively touring off road, I’d point you to a model with that mounting hardware. Otherwise, if you’re commuting to work, hauling a week’s shopping back from the supermarket, planning on weekend touring (including mixed terrain stuff) the Zephyr are well worth serious consideration.
Verdict: 4/5 Extremely weatherproof, solid and well-designed panniers with an equally enticing price tag.
