Gorgeous top, I wore it during the Spring Challenge. It was an overcast day with a little drizzle and then hot sun! I paired it with the Tarn Freeride Tank and stayed warm throughout the day, regardless of the changes in temperature etc. Didn't bother with a rain jacket. It was perfect, looks great too. Definitely true to size, although, could almost get away with sizing up if you want it a little looser fitting.
I love my Redwood Longsleeve for those autumn days with a mix of sun and clouds. It is perfect for going uphill as it never gets to warm in it and downhill it keeps me perfectly comfortable. I also already managed to test its durability during some crashes in the bike park and so far it holds up very well. Will definitely buy another one if this one ever wears out.
