It's a very short and squat design that sits low on my back and does look a bit strange when fully laden. However it is incredibly comfortable and I've had no issues with chafage or the pack bouncing. My back bears permanent scars from racing with packs with a longer back length but in 165 miles of racing in extremes of heat and 'dampness' I've not had a single problem.
Finishing a soggy Lakeland 100 with the low sitting Enduro Plus under my waterproof
For me the Boa anti slosh tightening system to secure and compress the water bladder worked as it should but solves a problem that doesn't really exist. Certainly the water bouncing and sloshing about is not something I've ever worried about in any other pack as expelling the air before sealing the reservoir also does a pretty good job. The wire and dial system adds weight and complexity and I had a few issues on the Lakeland 100 when with cold and wet hands kit was snagging on the exposed wires.
The website mentions stash pockets on the chest harness but I think they meant on the waist belt which features two spacious pockets. The lightweight floating harness did get twisted when putting the bag on but once everything was secured then the pockets were perfectly positioned and a pretty good size. An internal loop in th epockets for clipping compasses / GPS would be a welcome development.
The fashion is currently very much for race vests but if you are looking to carry a bit more equipment and like a more traditional pack with some very modern features then the Enduro Plus is certainly worth a look.
