The Shore is a heavy-duty jacket that'll take up most of the room of a standard daypack. It definitely blocks out the elements but on those middling days it's just too much jacket to wear.
However, it's super tough, so if you envisage bouncing off a few rocks or foresee a spot of trailside gardening mid-tumble, it's the one for you. The fabric isn't up to the technical standard of Gore-Tex and eVent fabric of many of the other jackets here, but by 'eck it'll keep you warm. All that weight does mean you'll get a sweat on, though, so if you're covering a lot of miles try and make them downhill ones. Ideal for cold uplift days on the mountain and Squamish forest drizzle.
