Quality of shirts / merchandise?

Does anyone know whether the long sleeve tees / pullovers have a fleece interior? I really want to get them but if the interior is made of fleece it can get really hot (and I already live in hot Singapore so… not a good idea…)

I wish they would list out the material of the shirts in the description box in the store. I bought the Minutes to Midnight white lyric tee and it was alright, but I also got the Chester black and white photo tee which is super super soft and comfortable. Makes me want to get more but I’m not sure which shirts would be made of the same material. I tried to email but I’m sure they’re busy, I’m still waiting for a reply.
