My partner cycles alot also (he got me into returning to cycling..about 18 yrs. ago ). I plan to get him a high viz cycling, sleevless vest with a slightly thicker front and the requisite zippered pockets that he requires.

It's a sort of garment for layering in cooler weather or for transitional seasons ..or for areas like California at this time of year.

Or a closer-fitting fleecy or cycling jacket to layer underneath. I'm sure with his weight loss he could use another one. He doesn't have to do laundry as often...

I most definitely would not be buying his prime winter cycling jacket which I know he's hunting down one right now. Usually he and I are each very picky and particular for our respective primary, more expensive outer cycling jacket that would be worn daily. Nor do I buy him any gloves..too risky because a person's hand shape may not jive with the way how the glove is designed. As we know, every little irritating wrinkle /scratchiness in ill-fitting key clothing pieces, get to be real pain when cycling for many hrs. on bike.
