The only complaint I'd have against them is you can't adjust the top of the cuff, so you get a small amount of wind get in if you don't have your sleeves pulled snug underneath Mine have a velcro strap around the middle, which isn't shown on that pic for some reason though
My logic for sleeve under glove is that when the rain drives towards you, it runs up the glove and onto the sleeve If I have gloves under sleeve, the water runs up the glove and into the sleeve Saying that, I've never tried sleeve over glove, so I'll give it a run tomorrow and see how it fares
The Rukka Armas Jacket has 'two sleeves' on each arm, one is tucked under the glove & the other over. Wind & waterproof ....Sorted... ( at a price!)
My logic, water runs down the sleeve into the glove, so sleeve out. Hand guards help deflect the rain coming up the sleeve. All personal choice and of course logic.
Whilst I always go for sleeve over glove, I also ride most of the winter with Toucano Muffs and BMW summer gloves, so it probably is not that important
You like your comforts. My commute doesn't warrant anything other than a decent glove. I am trying to save for new clothing, but will just make do with what I have.
Toucano Muffs are the best investment I ever made, cheaper than expensive gloves and far warmer and drier, hence why I wear an old pair of summer gloves i the winter. The posh gives are for riding the MTS
