I own plenty of Montane. Bought from LLS the Krypton in their last sale, something which seems to fit moderate activity around 50F or very active around 40F, it packs large considering it has only a little insulation so really for leaving the house to do something active for a few hours. Has a good hood.
They are selling the male Velo, color silver, I have from UK years ago, and wearing well, so I don't need another, the yellow version, mine gets used for moderately active in the high 50F's, has back panels to not get too sweaty. The Velo is extremely long, my male medium is above to tuck under bum when leaning forward on bike.
Pertex Microlight as in the Velo or Pertex Classic as in the Krypton resist very light rain, drizzle, mist, anything approaching a decent blob of water punches right through instantly. So if its wet and 40's low-50's then I move to Paramo, higher 50's upwards I usually just let myself get wet in Pertex as its warm wet and bodyheat can dry quickly once sheltered.
