After visits to several shops and a few days of online research I made the decision to go with the Osprey Exos 46. There was only one store in the area that had the Exos 46 in stock but when I arrived I discovered it was selling for less than expected (C$199 and not $219 as listed on their website). The “Large” size is actually a 49 litre pack that weighs 1100 grams … slightly more than expected due to a discrepency between the owner’s manual and their website. Nevertheless it’s more than 400 grams lighter than my current daypack so I’m not complaining. I plan to load it up and go for a walk tomorrow or Saturday … as soon as the scorching temperatures moderate a bit (the humidex reading was in the upper 30’s the last few days). I now have my gear list under 9 kilos not including water and snacks.
