Yes the Quito. The 2 main reasons it extends to warmer climates are
– there is less layers of fabric. The Velez has at the front the chest pocket and the through-hand holder, the Quito has none of these and just two "useless" mesh internal pockets
– the Velez has side vents from belt line up to sturnum height. The Quito has just above belt line through which you can access some useful hand warmers, right up and over as far as the elbow.
The Quito though is not a heavy backpacking type top because it is a jacket, not a smock, the Velez you can feed a pack's hipbelt through the side vents rest the hipbelt on your hipbones (none of that sagging sliding over fabric) and be aware the lighter materials (Velez Adventure Light, Quito, Vista) have less-tough external fabric so more ruffing off heavy pack. More your daysack and very light backpacking type.
I own the Quito, I sold my Velez specifically to extend Paramo goodness into warmer climates.
However don't over-exaggerate the extending into warmer climates I think I increased the temperature from like 10C to 13C/55F where I had to give up on Paramo. What I tend to do now is use the Quito and a windproof. The windproof for warmer, swap to the Quito for colder and add the windproover over the Quito for even colder. Hence so long as its below 55F for most/all of my trip, I'm ok with Quito. That still though largely restricts Paramo to winter.
