Why We Like The Outdoor Research Alpine Onset Half-Zip Top

Merino wool has quickly climbed to the top of the winter baselayer pecking order, due in part to the success of Outdoor Research's Alpine Onset Half-Zip Top. This midweight baselayer traps heat, fights odors, and controls moisture while we farm pow in the backcountry or enjoy our local ski resort.


Details

  • Baselayer designed for cold days spent in the mountains
  • Wool blend controls temperature, moisture, and odors

Very comfortable and warm

The wool is non scratchy; the fabric is perfect for a run in chilly weather and for layering when skiing. Love the colors too - I got one of each I love this top so much. The price is reasonable too. Size is standard. Very happy.

I have one in almost every color!

This is the ideal base layer, as well as an excellent all-around shirt for the cold weather months.

Runs a bit small

Gave as a gift. Recipient reports it's a little too snug, but loves the blue so much she doesn't want to part with it. For reference, I also gave the Alpine Onset 150 turtleneck with the Ubertube a couple months before, which fit perfectly.

Material is not good

I wear a size small in the Echo t-shirt. I ordered a medium of this shirt to allow room for a layer underneath. The fit was good. However, the material is not good at all. It is very thin and scratchy, not soft at all. It would not be comfortable to wear. I returned it.

Versatile and comfy wool mid-layer

I love this top and and am so glad OR brought these merino layers back. Nice mid-weight that layers well. I use it as a base layer skiing and run and bike in it daily. Bring back the hoodie too, please!

Great baselayer

This is a great baselayer top to be worn with a light shirt underneath. I tend to layer with an Echo tee. I use frequently when guiding clients on multi-day backpacking trips in canyons and the mountains. Light, great for layering, dries quickly. A staple in my kit.

Warm base layer

Size allows for a short sleeve under if desired. Perfect layer for fall hiking so far.

Nice color and design.

This is a nice color and the design is great. The fabric is a little scratchy and thinner than I expected.
