My biggest complaints are
-I am over 6ft tall and it felt a bit short in the arms, and worked less well on upright bikes vs drop bar setups.
-When I got off my bike it all dumped onto my thighs and got my pants wet
-the hood is a really weird not big to fit over helmet but a bit bulky fit under helmet
-i had several occasions gusts of wind blew the poncho from my back over my face
Things I loved::
-Light and packable so I always had it in my bag
-on the bike it worked really well
-looked great
-the hooks on the front hook to bars great leaving your hands free.
It's since lost its water repellence at the seams so I gifted it to a shorter friend to re scotch spray. I invested in the LX carradice duxback
things i dislike:
-heavier and bulky so I don't "always" pack it with me
-doesn't hook on the handlebars quite as nicely, but its longer so it kind of evens out.
-It may be warmer than the OPP, but only used it in Vancouver cold so far. All water proof fabrics I find a bit overly warm though, so ussually just wear wool if precipitation is light enough.
-takes longer to dry off completely
things I love:
-The hood is smaller and lined, so feel confident with vision and under helmet placement
-better fit as a tall person on an upright bike
-feels like it'll last a very long time and is easily refinished
-looks even cooler than the OPP, much more of a classic RSF aesthetic.
-has a tether so no flapping over the head (although I think OPP add this in recent models)
