Merino wool baselayers fall into two camps: the ultralight summer versions that feel barely there, and the midweight winter pieces that work better as standalone layers. Pearl Izumi's Transfer Wool Long Sleeve Baselayer sits in the middle ground that actually gets the most use—substantial enough for cold morning starts, breathable enough that you're not overheating two hours into a ride when the temperature climbs.
The fabric blend runs 37% merino wool with recycled polyester making up the balance. That ratio keeps the temperature regulation and odor resistance that makes wool worth wearing, while the synthetic content adds durability and faster dry times than pure merino. The Transfer Wool won't pill out after a season of regular washing, and it won't hold moisture against your skin during hard efforts the way heavier wool layers tend to.
Fit follows Pearl Izumi's Transfer pattern—close to the body without compression, designed to layer smoothly under jerseys without bunching at the waist or riding up when you're stretched out on the hoods. The long sleeves extend properly to the wrists rather than creeping up your forearms, and the hem sits low enough to stay tucked.... Read More
The merino content handles odor better than any synthetic alternative. Multi-day tours, back-to-back training blocks, or just minimizing laundry loads—wool earns its price premium over synthetic baselayers when you're wearing the same piece repeatedly. The Phantom colorway works under any jersey without showing through lighter fabrics, and the flat-seam construction eliminates the chafe points that make cheaper baselayers unwearable on longer rides.
Pearl Izumi positions the Transfer Wool as a three-season piece, and that tracks with how most riders actually use midweight baselayers. Cool fall mornings, spring rides that start cold and warm up, or layered under a jacket for proper winter conditions—it covers more of the calendar than summer-weight or expedition-weight alternatives at either extreme.
