Hi Alex! I like wearing gloves because it adds more padding between me and the bike when going over bumps and it also keeps my hands and fingers warm and functional when it gets cold.
Keep in mind... I'm the guy who rides a full suspension ebike in the city because my neck and back get sore... I'm just sensitive. I used to commute to work in Austin each day and sometimes it was hot so I used fingerless gloves
like these, other times I would use the full length gloves when it was cold and this really helped to keep my fingers from getting numb and slow on shifting and braking. I like bright colors so I got some cool ones from Fox
like these (good for when you do hand signals and want people to see you). That's why I also wear bright colored glasses.
In terms of helmets, I own a basic Specialized Propero II but also like the way Bell fits. I think it all depends on the shape of your head. Try some on in person and consider buying a cycling cap
like this to put underneath. It will keep the pads in your helmet from getting dirty and sweaty (wash the cap, instead of your helmet) just make sure you test helmets WITH the cap on underneath because it adds to the size of your head
I also got a basic cycling jersey that is brightly colored and well ventilated and I've seen many people with the
reflective vests. All of this extra stuff can cramp you style a bit (in my opinion) but having been hit by cars while riding... it makes you think twice about cool vs. safe.
