INOV-8 RACE ULTRA PRO 5 VEST

£130

inov8 race ultra pro 5 vest

That sinking feeling when you’re out for a long run and your gear starts to pinch is one we know well, so Inov-8’s claims of a comfortable and fully-adaptable hydration vest had us intrigued. The vest is marketed as a lightweight do-everything pack that can take you from long-distance training runs to ultra-marathons, extreme triathlons and, in this Covid-19 world of limited aid stations, the final leg of many triathlons going forward.

The Race Ultra isn’t short of pockets: there are six on the front for flasks, nutrition and phone, two on the sides, and a bigger five-litre compartment on the back for emergency kit. This vest can hold the gear you’ll need for all but the most demanding of ultra long-distance runs, without being too cumbersome.

The option to place the two 500ml flasks down on the hips with long straws, rather than up on the chest like most other vests, is a great feature. We found the vest extremely comfortable and it feels like it’s been designed for a variety of body shapes, while having the bottles in a lower position on the body helped us maintain balance when running over uneven terrain. Also included is a
re-usable Speedcup for races that require one as mandatory kit.

At £130 and weighing 370g with the (empty) bottles included, this vest isn’t the cheapest or lightest on test here. But, for the price and weight, you’re getting the great design and functionality that we’ve come to expect from the Cumbrian trail brand. 

Verdict: Versatile, comfy and adaptable: a great all-rounder vest pack, 90%

MONTANE VIA GECKO VEST

£90

Montane Via Gecko vest

You can buy the Gecko Vest for £75 and add extras (500ml flask £15; 250ml flask £13; straw £10) depending on what you prefer. And our preference are separate squishy bottles over one large bladder. Situated on the side, the 500ml bottles feel easier to carry, are simple to access (more so if you add the £10 straw) and refill, and slosh about less. The number of zippy pocket and back stash pockets are roomy enough for all your essentials without being cumbersome, plus the stretchy mesh ensures nothing bounces around. The vest fits well (two sizes are available) and those versatile front toggles are a touch of genius on this unisex pack, as for women it means you can move and position them comfortably around your bust! Plus, you get a safety whistle. 

Verdict: Not the cheapest but a superior pack with great features and comfort 92%

SALOMON ADV SKIN 12 SET 

£125

Salomon hydration vest

‘You get what you pay for’ rings true with the Salomon Adv Skin and it’s instantly apparent that this is a quality construction on par with the Inov-8 and Montane in terms of comfort, design and usability. The 277g weight is lean and achieves that barely-there feel on the run (even with the duo of 500ml soft flasks full), with the positioning of the vessels meaning there’s minimal bounce. The 12L storage volume is effective and there’s an insulated sleeve if you want to add a reservoir for an extra £32. Yet we’re currently content with the flasks, although the lack of extension straws does mean it looks like you’re trying to chew your armpit when taking a swig. The construction and durability appear strong and, if we had the stamina, we’d happily run all day in this. 

Verdict: A high price but all-day comfort and smart features abound, 88%

CAMELBAK HYDROPAK 

£44.99

Camelbak hydropack

Camelbak say this is for cycling (but can work for tri and running), which helps make sense of the minimal storage, assuming you’d have other storage on your bike. The focus is very much on hydration with a single but capacious 1.5L reservoir in the back, which is simple to refill due to a plastic screw-access opening and handle. Once filled, this small-framed female tester found the pack weighed too heavily on the back/shoulders and the straps cut into our underarms. The single fastening feels weedy (larger-busted athletes will find it a struggle) and we’d want comfort factoring higher, as well as a waist strap. You could use this for running, but the lack of storage would be a problem for any trail adventures. The single zippy pocket was also too small even for our mobile phone. 

Verdict: Okay for cycling, but lacking both storage and comfort on the run, 60%

EVADICT HYDRATION BAG 5L

£17.99

Evadict hydration pack

Given this pack from Decathlon includes a water reservoir, that RRP is insanely good value and draws favourable comparisons with the Montane (and the grey version is currently £13!). Both have comfy vest-style designs, which avoids weight pulling too much in one area, and both have many pockets for stashing essentials. Here, hydration is a single 1L back reservoir, which is fiddly to fill but does the job. We prefer the side flasks of the Montane when running, but the Evadict wasn’t uncomfy. One large back pocket sorts out valuables, while front stretchy pockets can handle a jacket or fuel. It chafed a little on our shoulders, but broader athletes should have no troubles. The chest straps feel secure and can be moved up or down, and a whistle is included. 

Verdict: An insanely good price, and everything you need to get started! 83%

ULTIMATE PERFORMANCE AIRE 2LTR RACE

£54.99

ultimate performance hydration pack

The Evadict above shows that smart design can overcome budgetary constraints. And the £54 Aire? Sadly not. Much of our frustrations revolve around the sheer mess created by the strapping system, the excess of which flap around after any kind of oscillation, while the solo chest strap just isn’t enough to secure the bag in place without excess bounce. The 2L reservoir is also flawed due to being difficult to clean and boasting a cheap-feeling bite valve system that’s unnecessarily convoluted and requires plenty of suction. The above points are a shame, as there’s a decent enough main bag here with ample storage options, a helmet mesh and padded areas to make it adequate as a commuting or walking bag, but that’s really not what this test is about.

Verdict: Will do the job for pottering, but too many flaws for a serious run contender, 58%

OSPREY DURO 6

£100

Osprey Duro hydration pack review

Osprey’s cycling packs come highly recommended, but their debut run offering, the Duro 6 (litre) – also available as a women’s Dyna or smaller Duro 15 – is a hit and miss affair. The hits are the straw extensions, which makes it easier to swig when on the move, and the sheer array of pockets; some zipped, some cavernous, but all secure, durable and neatly positioned (there’s even an attachment for a helmet, although we’re not sure how much we’d use this). And the misses? It’s the words that no-one wants to read when assessing a hydration pack… the bounce. We (and  running pals) just couldn’t get the two 500ml flasks to stop moving up and down when containing liquid, something that may be due to the flasks being located more centrally than Osprey and Montane. 

Verdict: Top flasks, fine storage but just two much bounce when on the move, 76%
