This item is not too bulky, so it is decently packable, but is not designed as a packable jacket. The outer fabric is nylon, so there is some water resistance.
Sure, you can pack it easily in a suitcase. I don't know if it would work in a backpack. Yes, the exterior is water resistan. I've worn it during snowfall but not rain. It's my favorite running jacket.
Hi there, while I did not keep this jacket, I loved the materials and believe it will be great traveling to Scotland, but not as the only layer in the wintertime! Be sure to have some wool base layers to go underneath. I think the outer material is water shedding (not proof). I think you could pack it down, but not to a tiny thing, after all, it is wool you are compressing. Yet, it is the real wool insulation that makes it feel really great and dependably warm when on so that dampness won't feel bad at all! If it looked better on me I would be wearing it!
No, the jacket is not bulky at all and can easily be squeezed, rolled etc. As an aside, don't know if you have ever used the vacuum packing bags before but they are great for compressing especially for all that wool you should take!
As for water resistant, I just stuck the sleeve under the faucet and it does appear to be pretty water resistant.
Have a great trip!
Can it be squeezed and rolled? Not really. It is not like a down jacket that compresses. So it has to be packed just like you would pack a substantial sweater. Is the exterior at all water resistant? I walked my dog in some light rain for about an hour, and that is the only test I base my judgement on. I did not feel wet, I was comfortable and dry. So I would say it has mist (but not downpour) resistance based on my limited experience.
I think it would be good. Rolls up and would be warmth without bulk
