Great Mid-Layer

Superb weight-warmth ration. Just enough to keep the chill off while moving in the mountains. I frequently ski in mid teen temps with just a tee shirt base, the R1, and my hardshell. I love the thumb holes and the sporty fit because it stays out of the way of ropes, harnesses, etc. The chest pocket is good for a gel or phone. The R1 is everything thing you need and nothing you don't.

The Perfect Mid-Layer

Coming into the 2015 winter season, I was in desperate need of a new layering system (previously owned pieces were just a bit... well, worn. You get the idea). I have had a Chrome Industries Storm Cobra Jacket V1 for a few years that has been an amazing shell in the fight against wind and rain. The only issue with the shell is that it's not too warm and it is slim fit which does not offer a lot of room for layering... but I look real spiffy in it so good job Chrome. Being a college student, my funds didn't really permit me to purchase a whole new layering system so I set out to find a lot of warm for minimal bulk. A lot of my studies brought me to the Patagonia R1 series. I decided to take the plunge and give it a go after all the positive things I had heard about it. The fleece arrived right before a big cold front set in here in Fort Collins, CO. I decided to put the pullover to the test and threw it on over a standard cotton long sleeve before biking to class. At about 40-45 degrees F, the R1 was perfect "by itself". It cut enough of the wind from the bike ride and kept me comfortably warm while remaining very breathable. About an hour and a half went by and it was time to bike back to the apartment (a little smarter, I might add). The temperature had dropped to about 35 degrees F and the wind had picked up quite a bit. I simply threw on the Chrome shell over the R1 and hopped on my bike. With the shell blocking the wind and trapping just enough heat, the R1 did an amazing job of once again, keeping me very comfortable. I didn't over heat and I was never chilled. With water-proof shells, it is sometimes difficult to layer with out feeling 'muggy' but the R1 feels extremely breathable even when it isn't the outer layer. I was really impressed with the performance of the Patagonia R1 but 35-45 degrees F is a pretty narrow window as far as temperature goes and I hadn't been able to really test the garment's versatility. Finally, I got the perfect day to see what the R1 is made of (figuratively... literally, the R1 is made out of 93% recycled fleece and 7% spandex). Temps were hovering around 20 degrees F so I through on a Smart Wool NTS Mid 250 as my base layer, the Patagonia R1 over that, and completed the system with the Chrome Storm Cobra. I decided to use the hidden thumb loops featured in the R1 and through on a pair of thicker wool gloves. The thin material at the wrists of the R1 are perfect to fit under form fitting gloves while the thumb loops are being used. I started the bike ride and was amazed at how warm I was with out overheating. The day's weather progressed in typical Colorado fashion as the temperature fluctuated a great deal dropping to about 15 degrees and jumping to close to 30. I was able to open up the vents on the shell and unzip the R1 to allow some more airflow when the temp raised and it was just as easy to reverse the process when the temp lowered. I try to find flaws in every product I review (seems to add more credibility to the review) but I couldn't find anything wrong with the Patagonia R1. I love the chest pocket that acts as another vent when opened. The longer zipper allows for a greater range of airflow to accommodate a vast range of temperatures. The slim cut of the R1 obviously is a bit more snug but there is just enough stretch in the fabric so that it won't hinder mobility. The longer torso looks great for warmth and allows you to throw on a pack with out worrying about your fleece riding up. There are just so many things right about what Patagonia did with the R1. I couldn't be happier with my purchase and with most of my money going to the University, it's always nice to end up with something that is versatile, functional, and pretty darn stylish. Good job, Pat.

A great layering pullover for those in between weather days. Perfect for a walk or bike ride. I look forward to wearing this fleece as a layer under my ski jacket once the slopes open.

For starters, I live in Colorado and like many am a 14er-ophile. I hiked 20 this summer for a total of 30. I got the Patagonia R1 Fleece Pullover a quarter of the way through the season and it was an immediate game changer.

I bought a medium, even though the small fit snugger, because I don't like my layers to be skin tight and I like to wear it over T-shirts off trail. I am a bit of a minimalist hiker and only like to pack/wear the essentials to keep weight low and speed up. I layer with a dry fit tank, the R1 and over that the Patagonia Nano Puff Hoody. I wear trail running shorts, and La Sportiva Bushido trail running shoes to give you an idea of how light I travel.

I did several long weekends hiking 2-5 peaks at a time and lived in the R1 the entire time. Hiked in it, slept in it, sat around the fire in it and went to dinner in local towns in it. It is probably the most versatile and comfortable piece I have. When I started hiking at 4am, I zipped it to the neck and put the Nano over it and was adequately warm in the 40s. When the sun came up I would lose the jacket and unzip the half zip front to catch a breeze. It breathes well enough that I also trail run in it (during the winter) and stay warm but not over heated. Another upside is that despite wearing it for nearly 36 hours straight with a tank underneath, it didn't retain odor. That said I am a minimal sweater, but I was impressed just the same.

In terms of style, it looks great for casual wear and if you're like me you buy gear that you can wear on and off trail. I like an outdoorsy look so I wear it several times a week when I go out to dinner or a movie. I even bought a second so as to have a different color and so I wouldn't wear out the first one. So with all that said, its durable, warm, breathable, stylish, retains shape, doesn't hold odor and if you catch it on sale you can't beat it! I am the type of person that ONLY buys what I need, and it must be a durable jack of all trades piece. I even wore them on a plane and daily throughout a week long visit home to the south last month.

(To all the people that complain about the long sleeves... they're meant to be long so they double as a partial glove. Roll them up and get over it.)

Pick one up and you wont be disappointed!
