Review by Erin Trail

The Marmot Rocklin Rocklin Half-Zip Pullover is a cool to cold weather standard for a reason. With proven design and 100 weight fleece, this half-zip pullover is ready for nearly any activity.

The Marmot Rocklin Rocklin Half-Zip Pullover seems pretty standard but there are a few elements which make this layer stand apart from the many other fleece pullovers on the market.

The main differentiator is the fleece fabric, which is REPREVE®, 100% Post-Consumer Recycled Polyester (195g/sqm). The pullover is light in your hand at around 14 oz. The fleece is a really nice feeling pile and density that’s fuzzy but not shaggy. Most importantly, the knit of the fleece is tight enough where it provides a bit of wind protection.

The bottom hem, wrist cuffs, and neckline are wrapped in an elastic non-fleecy material. The hem fabric is nice on the wrists but can feel a bit scratchy and stiff around the neckline.

The Marmot Rocklin Rocklin Half-Zip Pullover was really handy on several late summer and early fall camping weekends. The jacket stashes easily in a bag or in a van-shelf and doesn’t show any wrinkles or residual lines from storage. While basic (i.e. no pockets), the pullover does its job: keeping the wearer warm and comfortable.

The only thing to note: the Red Mulberry colorway presents as brick red on the website. In person, this color is a bit of a shapeshifter, going from a dark raspberry in shade to a bright darker pink in full sunlight. So if you want more of a dark red color, this is not the colorway for you. But if you like a fun dark reddish pink, this color is perfect.

The Marmot Rocklin Rocklin Half-Zip Pullover fits true to size and is available in three colors and ranges in sizes from XS to XL.

Trail Boss of Stoke

Erin Trail’s hobby is collecting hobbies. She’s a 5th Generation Coloradan and grew up exploring the outdoors on family camping trips and hikes. Her first backpacking trip was at eight years old to Grizzly Reservoir – she proudly carried all of her own gear those 3 miles from the main parking lot to the Reservoir.

Erin is an adult-onset athlete who started as a Masters Swimmer and then developed into a triathlete. She has completed 5 Ironman races and nearly 20 x 70.3 distance Ironman races, including the World Championship in Lahti, Finland, in 2023. In 2025, she raced for Team USA in Pontevedra, Spain for the World Triathlon Cross Tri World Championship. She placed 9th in her age group and was the 1st American woman in her age group.

Somewhere along her triathlon journey, she picked up deep love of cycling. Cycling encouraged her to see landscapes in a new way, learn new skills and to develop self reliance; now she often goes and does Type 2 rides just to see if she can do it. She’s got all the bikes: gravel, mountain, fat bike, time trial and road.

She is even known to combine her love of camping and cycling and go off on solo 24 hour overnight bikepacking trips in the mountains of Colorado. In addition to bikes, she teaches yoga, lifts weights, skis, SUPs and has recently purchased a campervan.

Erin is a former Montana park ranger with a degree in environmental engineering. She loves getting into technical details while putting her gear (and herself) through the paces. She shares her home in Colorado with her husband, Will, and her 3 cats (Zipper, Brewtus, and Simcoe).

Fall and winter 2025 will bring Erin to the “Adventure Side”, with many camping, vanlife, bikepacking, and mountain bike rides. Once the snow flies, she can be find resort skiing, fat biking, and triathlon training (inside and outside).

2026 will bring a National Championship Cross Tri race, a National Championship Road Sprint and Olympic Distance race, and hopefully a chance to represent Team USA once again in 2027 in Edmonton, Canada. She’ll also save lots of room for adventure time with her friends and husband.

When not adventuring, she can be found on a sunny patio somewhere, drinking beers with her husband.
