Hijab help

Salaam lovelies, I need some help with hijabs! I’m going to perform Umrah in Feb (InshAllah) for the first time since reverting and I need to know what hijabs/burkas are best for the weather! I struggle having anything tight round my neck even turtleneck jumpers aha but love the loose looking material hijabs with the undercaps! I really don’t know what to look for and also if anyone has any Umrah tips, please share!
