Alf Alderson reviews the Raidlight Olmo 20, a trail running pack that allows you to carry several litres of water with ease and comfort

Great for carrying extra water; very light
A bit floppy and unwieldy when not full

The Raidlight Olmo 20 hydration pack makes it unlikely you’ll ever go thirsty again whilst trail running or hiking, since not only is it able to hold a hydration reservoir, you can also carry two water bottles on the shoulder straps and there’s additional carrying capacity on the outside of the pack and in mesh pockets on the side.

The Olmo range of packs were originally developed in co-operation with the Italian veteran runner Marco Olmo who came up with the notion of having water bottles carried on the shoulder straps as a balanced and convenient way to access hydration on ultra-running events where weight and practicality are essential.

The pack itself is very light, with a 20-litre main compartment plus several additional zippered and Velcro-fastening compartments and bungee cords which whilst useful for larger loads can be a bit unwieldy if the pack isn’t pretty full.

The shoulder straps, waist belt and back have mesh padding which ensures a comfortable carry and the pack comes with a one-year guarantee which is good considering the harsh wear it’s likely to get.

The Olmo 20 is aimed fairly and squarely at trail runners, but if you like to travel light when you’re hiking – especially in hotter parts of the world – you may also want to check it out.
