With the second half of the summer being particularly unsettled weather wise then the chances are you will have been walking a lot in the rain recently?  Especially on longer distance walks, I head in to Glen Tanar from Aboyne the other weekend and it rained for 3 of the 4 hours I was out walking.  It was a muggy and humid day and the Fungle, felt more jungle like but my CragHoppers and t-shirt were keeping me cool enough, but on leaving the tree line behind the open heather moorland brought steady and heavy rain, and a bit of wind, nothing to strong but enough to dramatically lower the temperature.  A few years back I got a pair of made to measure water proof over trousers.  With no lining they are light to carry and easy to roll up into a pocket, zipped at the bottom to save you taking off your boots, but you still need to have good balance to get them on quickly.  I also had a shell outer jacket.  I was wrapped up from both the wet and the cold wind.  I had not been for a long-ish walk in the rain for ages, no views to take in or Buzzards soaring in the sky to watch but it was enjoyable enough, especially guessing when the could might break.   Then it came time to descend and the valley bottom was a lot warmer, the rain became more showery and I could remove the over trousers.  The day became warm before a big shower ensured I finished my walk in the rain as I returned to Aboyne.
