Ultimate Direction FASTPACK 20

The latest offering from Ultimate Direction, the Fastpack 20 Vest/Backpack, available from www.ultramarathonrunningstore.com.


“Providing all the features and capacity you need and nothing more, the Fastpack 20 is a streamlined pack that will get you there and get it done. Perfect for day hikes, peak bagging, or a quick weekend, the Fastpack takes inspiration from our Signature Series vests, with its super comfortable and stable fit.” (http://ultimatedirection.com)


The pack offers a versatile approach to hydration, offering front, side and bladder options, or indeed all 3 or any combination of, that’s likely to be one of the main attractions of the Fastpack 20 for anyone looking for a pack that’s equally at home whether running, fastpacking or hiking.


It’s described as building upon Ultimate Direction’s Signature Range, with the functionality and capacity of a regular backpack but the fit of a running vest/pack.


With 5 accessible compartments on the front, 15 to 20 litres of capacity with compression straps to remove any excess, a waterproof rollable top closing mechanism, two adjustable sternum straps and 2 large mesh side pockets, capable of holding everything from bottles to tent poles and/or trekking poles, it’s a pack that’s likely to have wide appeal.


The Fastpack 20 comes in 2 sizes, Small/Medium and Medium/Large. After months spent waiting on the PB Adventure Vest last year I was gutted to finally receive it only to find that I couldn’t fasten the straps across my chest, so it’s good to see two sizing options for this pack.
