Hey there @pillowPANTS
@neph93 is correct per usual, but I'll layer my take on:
They're fine in any weather, but 14oz would IMO be better for hot weather (I have the 14OD, so it may differ–I'd bet if anything slightly less breathable and tighter, so the indigo may press the advantage further). The 18oz is one of my favorite denims of all time though so if I had to get just one I would deal with the minor difference in climate between the two and have a solid all-season jean. The 14oz is also an outstanding denim.
Thanks man!!
I wear the 22oz pronto jeans all the time but they are a lil too warm during the summer. Even on my bike i feel they are too much. My Strike Gold (current summer pair) need to go and be replaced.
Id rather just plain indigo then OD as i have a pair of SBG and they would look too similar
