Why We Like The Outdoor Research Alpine Onset Merino Quarter Zip Baselayer Top

Outdoor Research's Alpine Onset Merino Quarter Zip Baselayer Top is a favorite for a reason. The lightweight merino wool blend features recycled polyester for added durability and moisture management, plus an earth friendly touch. Merino's natural anti-odor and thermoregulating properties keep us prepped for a full day on the hill. Flat seams keep chafing out of mind, and thumbhole cuffs hold sleeves secure while we're on the move.

Great base layer

So far I have used it for resort and backcountry skiing and it has worked perfectly for me. I am 6'1", 170lbs and the L fits well.

Not recommended

Fabric repeatedly sheds large amounts of dye. Fabric sheds large amounts of coloured dye on skin when worn, and sheds large amounts of coloured dye in the washing machine when laundered. Unwearable and unusable as a result. Not recommended.

Excellent lighter weight baselayer

Great wool baselayer - lighter than some of my heavier ones, which is exactly what I needed for touring. Doesn't get too hot on the uphill compared to the heaver weight merino baselayers I have, still keeps my warm enough, easy to layer with, really enjoying it!

Nearly Perfect Pullover

Thin merino wool is warm enough for cool fall weather, but breathes enough to wear comfortably indoors at room temperature. The material does start to pile after a few months of wear, but it doesn't affect the functionality.

Awesome!

I bought this for my husband and its one of the most worn items in his closet. He has a really muscular build, so he is always looking for low-bulk layers and this is perfect. He likes that he can go directly from a zoom call (looks dressy enough on screen) to working outside (durable) to skiing (warmth under a ski jacket). He finds that he wears it most often as a mid-layer, but has worn it next to skin, as well. I am online buying him a few more in other colors right now!

Warm and comfortable

Kept me warm and dry despite how much I sweat. Very comfortable and the thumbs holes make layering up easy.
