Gets Smelly

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:True to size
  • Size Bought: Large

I use it for hiking and find that it smells after a longer hike, unlike my meranio wool tops.
Great fit though and very comfy does keep you cool.


  • Fit:Runs small
  • Size Bought: L

I ordered according to the size chart provided and the shirt looks like it is youth sizing. The shirt feels like it would be super comfy for any outdoor or physical activity, unfortunately I will not be able to wear it.

Great shirt

  • Familiarity:I've used it several times
  • Fit:Runs small
  • Size Bought: Large

I first ordered these in a medium as I usually wear a medium in tops but these are very fitted for active wear and I don't like anything tight on my stomach so I returned and ordered a large in Rose and Zing and now am very happy with the fit. I love wearing them hiking for the sun protection as well as the lightweight fabric and they can be dressed up too.

Soft and stretchy!

  • Size Bought: XL

I came back after buying two of these on sale, looking for more. Darn, there aren't any other colors. This top is close fitting, VERY soft, VERY stretchy. I can feel the seams, but not sure I would have noticed if it weren't for the other reviews. This is a great shirt! I'm taking it on a month long bicycle tour this summer.

Very fitted! Medium, 36B.

  • Familiarity:I returned this product before using it
  • Fit:Runs small

I always wear a medium in Columbia and this was smaller than all my other mediums. It would have been ok, but I could feel all the back seams right behind my armpits and that would drive me crazy if that feeling didn't go away in the laundry. I put on the second one that came with my order and that cinched it- they both went back. 36B- medium was very fitted. I moved my arms as if running and I could definitely feel those seams.

The best shirt ever!

  • Familiarity:I've put it through the wringer
  • Fit:True to size

I love everything about this shirt, the material, the fit, the colors... I first bought a pink one that I love so much that I bought a orange one as well. It's good for running, climbing, hiking on hot weather, keep you cool and dry, Amazing!

Great fit

  • Familiarity:I've used it several times
  • Fit:True to size

The fabric weight is perfect and breathes well. Sizing is great, I'm a medium in 90% of tops like this and a medium in this fits just right. I have a complaint, though. I agree with Laurie W Casey that the seams on the back of the shirt in the shoulder area are pretty poor. I can feel them, and, yeah, they itch a little until I'm used to them.

Looks / Fits Great...Itchy as &#(

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:True to size

This is a very nice looking and fitting top. Super soft on the outside, but the seam stitching on the inside is pretty itchy and uncomfortable. I'm rather tolerant of itchy tags etc., but this is kinda bad. 5 stars for look/fit/outside feel 1 star for overall comfort. The sizing seemed dead on to me. Normally wear a medium - the medium I ordered fit perfectly.

Great Top

  • Familiarity:I gave it as a gift but have feedback to share
  • Fit:True to size

I purchased this item as a gift and it is wonderful. My mom loves the material and uses this as not only a running and hiking shirt, but for yoga and horse back riding. The shirts holds up to wear and tear and she has not encountered staining problems at all even when it can get dirty at the barn. Light weight and breathable and as a bonus a solid 50 UPF rating.
