IMHO a 33 lt pack is far too much for a day hike. As it is winter you will be having lots of clothing on you which already creates some weight. <br><br>For a day hike proper clothing and a small pack with basic needs in it not exceeding a few kilos will be more fun on the track.<br><br>Keeping your water on your waist under your coat gives less pain and will be kept warmer. Cold water is no good in winter. Two normal size canteens would be more than enough considering you carry less on your back and sweat less.<br><br>Have fun,<br><br>Burak<br><br>
