The fabric/material seems high quality, and I haven't had an issue with it.
I wear this jersey (alone, no under layer) for early morning rides up the nearby canyons. When the temperature is around 50 F, plus or minus a few, I'm totally fine, even going down the canyons on the way back home, but I haven't tried it on anything colder yet. When it's in the upper 40's, I'll be a little bit cold at the start of a ride, until I get warmed up. I usually have to leave before sunrise, so it does get warmer on my ride, but that's about as close to a temperature rating I can give (I don't get bothered much by it being too cold, unless it's on my hands and feet).
I've only worn it in dry/fair weather, so I can't comment on exposure to rain, etc.
Have only had one real rainy commute day where I've used these so far, so two rides and 26 miles total so far. I've been injured so have been doing more remote work lately. I have some other Endura products and they've been amazing, especially for the price, and these feel like they'll be similar as far as the quality and durability. Their single walled but the seam taping looks really well done. Legs got a bit warm and sweaty but I've never had rain pants not so that. My only two complaints, which are minor, is that the bottom cuff area doesn't open up much so I can't have my shoes on to get the pants on or off. The second is that they're a little too roomy in the seat area for me, so they can sometimes snag a little on the saddle nose when I'm getting back on the saddle after a stop light. I know they have to design for a certain body type and I may be outside those parameters a bit (I'm somewhat muscular but slender), so can't ding them too much for that. Overall they feel pretty good, though, and would look for these again if they got damaged from a crash... or an unleashed dog attack, which happened to a different pair of pants not too long ago.
I got this jacket for a nine day ride across England. It drizzled or rained every single day so I used this jacket all the time and it kept me cry and comfortable. When it was nice and warm, I shook it out and rolled it up in the panniers and it was ready for the next day. It shed the rain and the mud and dirt like a freshly waxed car.
The Endura Men's GV500 Reiver Jerseys are my favorites of all my jerseys and I have several! The fit is snug it perfect, not too tight nor too loose and the material is very stretchy. I love all the pockets, I go on long rides early in the morning so I am often pulling off layers as the morning progresses and these jerseys give me plenty of space to store said layers. They are nice looking with a classic appearance. I purchased four different colors. Oh and they feel really good once you have worked up a good summer sweat managing the transfer very well.
