I use this model in the 35-liter variant for over two years almost daily - for cycling. Ok for he is not first thought - as the name says - but he was exactly my demands on a bike backpack - good body position, that is not so far distanced and visibility - (Helm yes - but safety vest is me too stupid). Thus, the question is already explained why that color. The fit is very close to the body and ergonomically - hence the four sizes. I have the 35 liters in M L although I would have had to take - but I noticed only after a year that there are different sizes - although I bought the part in a large shop. That is - the thing has a good and tolerant fit and very good adjustment. The tight fit also has a disadvantage you sweat very easily - a ventilation is hardly given - what riding a bicycle not so disturbing as the wind whistles anyway, though, and now we come to the part for which the part was built - in the mountains at a good pace, it is with me from 5 ° C outside temperature something warm. I have the part so far once used on a low mountain hike, repeatedly pass hike in the Alps and even when crossing the Greater Caucasus in Georgia. And because the backpack was able to show what he can be seen out. The payload was always about 10 kg - most of it technical instrumentation. The slim design means that the weight is distributed perfectly. Through the bright material can be found in the interior always fast everything. The two pockets and in the lid are great for quick access, just like the side engagement. The side fastenings for my sticks (Leki Carbon Lite XL) can be so easy to operate, which I also use time and again. The crampon attachment I have used only in the Caucasus - otherwise I grab the water bottle in there. The rausnehmbare insulating sitting mat is a nice gadget, but which I usually take out - just like the waist belt - which is possible only in the mountains and as decent does his services. The backpack is only conditionally waterproof - and then only on the underbody - if I have the whole day raining always be at least one liter in the ground (as it flows badly) - by whatever Backpack covers (but is also the tight fit for problem) - the water always found a way in. In the Caucasus, I had a Pocho then this (exped Poncho extremely) and how it works just stop. Conclusion: Why I give the part now 5 star - because he has what replaced two years without significant damage, except the logo printed on itself (which makes him more sympathetic) has survived all bets. All seams are tight, the zippers are still working, the nylon material has little roughness and the main closure with aluminum hook is just awesome. There is the possibility to modify depending on the use the backpack - wearing parking, sleeping pad and waist belt can degrade, thus reducing the weight Now one can only hope that one of the few things that still remains good and indestructible build in quality get the Americans and not any "innovation" ruined the product - for which I am also prepared so this - but to pay opulent price. PS: The backpack is in Amazon as "Ladies Backpack" - from wherever is this nonsense - the backpack is not a more explicit "Ladies Backpack" (such as Gregory "Jade" etc) - on the product images are the only men watch - But perhaps these are just the "experimental rabbits"? Dear ladies, that is, it may not work but it must.
