As promised here is what I have decided for as a RTW setup. For those looking into sizes as well, I am 178cm , 66kg, rather slim with a 92cm chest. That's what I finally chose: Baselayer: Icebreaker Merino 200 - Size S 1x long sleeves, 2x short sleeves Protection: Forcefield Pro Shirt X-V 2 - Size S I finally decided for the Forcefield over the Leatt 3D Airfit, if you're a slim guy definitely give the Forcefield a try! Midlayer: Adventure Spec Baltic Hybrid Jacket - Size S I love this one. You can easily wear it as an all-day jacket, and you won't believe it stretches over the Forcefield - but it does. Really cool! optional Midlayer: Adventure Spec Baltic Insulated Jacket - Size S Wearing this one as midlayer results in a *really* tight fit of the outer layers. Tests will tell if it finds its way onto the overall packing list. Outer Layer: Linesman Jacket - Size S | Mongolia Trail Jacket - Size S Still not decided on these two, but I kept them both for now as they are really great jackets. For my trip to Iceland in 2020, which will be a test for the RTW-trip, I will surely use the Linesman as it will provide more protection from the elements. The main problem I faced here is the battle of sizes. Baselayer+Protection+Baltic Hybrid, Size S fits snugly but actually just right - I am simply used to a much looser fit from my BMW Rallye 3. I also tried the Linesman Size M. It would have allowed me to add more midlayer-material (e.g. wear a Baltic Hybrid + a Baltic Insulated). But I simply looked funny with the bigger jacket *without* all the layering - and it didn't give me a good feeling. Rain+Cold Protection add-on: Trail Waterproof Shell - Size M As you can see, only for this one I went one size up. It is simply impossible to wear a Size S as well - have tried that with the Atacama Race Shell first but same surely applies here, that's why I only ordered an M. Pants: Atacama Race Pants - Size 32 I have also tried the Mongolia Trail Pants. I like the ITB-style better. The Mongolia Pants fit just as well, but the legs (for my size) are a bit too long, so that - when you're out of your racing boots - I would be left with quite some material. So the Race Pants were the way to go. One word on neckbrace compatibilty: I first tried the Atacama Race Jacket, because of the "hole" provided, which would have left me with the option to fix the neckbrace to the Leatt 3D Airfit. I now use the neckbrace-straps, and that even works wearing all layer, also with the Trail Waterproof Shell. And finally (a bit OT, but to complete it:) Shoes: Sidi Crossfire 3 TA | Helmet: Touratech Aventuro Carbon2 black Conclusion: Adventure Spec offered me all the choices to build my own personal light layering setup. My whole process started with looking into a Touratech Companero World 2. Looking at the money I have spent now, I am almost on par with the Touratech, but I'm travelling much lighter and much more versatile. Living in Germany, the only drawback I see so far is the mail order and returning costs from/to UK, which in my case added up to about 90 €. Anything else: Thumbs up, guys, and keep up with the great work! Arrive alive!
