Atak Equus Equestrian Gloves Adult

I am currently 58 looking to restart riding for leisure. Been riding since 18 but stopped about 20 years ago... Looking to get kitted up. I live in Malaysia where it is fairly hot and humid and will be riding only in the morning and evenings... I am 5'10:, weight 200 lbs. I am interested in the following items but have some questions which I hope you can help with. 1) Charles Owen Hampton Hat (Black). My measurement is 58 exactly.. Head rather round and bald. Do you recommend the 58 round fit or 59 round fit 2) Rhinegold Elite Seville. My size is UK 9 with calf width 40/41. Will the one in stock ie. UK 9 and Regular width fit? 3) Also interested in the Mark Todd long leather field boots but a little condused as to how you measure the calf height. I see you do have a UK 9 as well 4)Rhinegold Elite Luxus Leather Standard Height. You have a UK 9 and wide. Would you recommend this? 5) Breeches... My waist is 40 and so what leg size would you recommend. How long does it take for the goods to reach Malaysia?
