Pearl Izumi Men's Quest Thermal Jersey

Decently warm. Pair with a base layer if in the upper to mid-40's, base layer and jacket if low 40's to mid 30's.

Fit is not super slim like some Italian brands (good for my Clydesdale-ish frame), and a little short in the torso. Overall great jersey especially for the price compared with other brands like Castelli, Assos, Rapha, etc., but still with excellent quality.

This isn't one of those winter weather jerseys. It's more of a fall or spring jersey. The fit is very loose. In fact, I probably could have gone a size smaller, but the loose fit isn't a problem during the ride. On those days when it is a bit cool (55- 60 deg), the jersey by itself is plenty to keep you warm, maybe even a bit hot. I wear an under layer tee shirt and arm warmers if the temperature is cooler (45-55 deg).

I love the quality, style, and warmth of this jersey and it's extremely comfortable top layer on mildly cool mornings (lowest temp so far that I've ridden in with this jersey is about 45F). I bought a Large and the sleeves were the perfect length for my slender/average build 5' 10" frame. My only issue is that it is a bit shorter (top to bottom) than my other long sleeve jerseys and rides up more than I would prefer.

Great for the colder weather

The PI Quest Thermal jersey is very comfortable and sized correctly. Nicely made and recommended for cooler weather in the 50's. Wish the color was more yellow than green.

Great Jersey for riding when temps are in the 50's. Can work for lower temps with a vest and arm warmers underneath.

Not too hot and not too cold - just right. I wear this as my middle layer when fatbiking during winter in Anchorage, AK. It helps keep me warm without trapping too much heat. Good, normal american sizing. The price is right too.

COLDER WEATHER RIDING...GRAVEL AND MOUNTAIN BIKE.

I like the way this jersey fits and provide warmth without adding a lot of bulk.

Simple, warm, inexpensive

My racers body is gone. Actually never had one. But I love the loose fit of this jersey. Just warm enough in combination with the Quest Convertible Jacket to ride in the mid 40s.

Very good for chilly riding, 45-55 degrees. I bought this for colder winter days here in SF Bay area. I'm a big gut rider, but this medium jersey fit me just right.

a very nice warm winter jersey.

Extremely comfortable and warm for 45-60 F temp

I was pleasantly surprised by this budget long sleeve jersey. It is perfect for me when I'm out on the bike when the temperature is in the 50's and low 60's. The fabric is very soft and the sizing/ cut is generous, definitely not a race cut garment; it runs a bit large too, but I like the longer sleeve length. I wouldn't recommend it for temps below 45 or riding in wet conditions.
