Great travel shirt

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

I am very happy with this purchase. To get a shirt that is stylish for going out and still has the performance that you can wear it for a hike or scramble. It covers many bases for when you have to pack light.

I would give it a big thumbs up.

Great Shirt, sharp.

Purchased one for my son, he loved it so I got another color! They are awesome, look great and are sturdy.

No complains here

    Comfortable and really true to size

    Strange sizing on the shirt

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: Medium and Large

    The material on the shirt is very light and the design is great but none of the sizes fit me. Every shirt I have is a medium but the medium in this shirt was way too tight in the chest and somewhat tight in the shoulders -- it felt like a small. The large was too large in the back and shoulders -- it looked like it was billowing on me. I had to return both. Make sure you look at Mammot's size chart before purchasing -- I noticed (too late) that their chest measurements are different from most other companies.

    great for tropics

    This a great shirt for hot climates. It is light weight and keep you cool. Not only can you wear it out on town but it is great for adventures. I also love the collar for keeping the sun off my neck when climbing.

    This is a really nice shirt

    • Familiarity: I've used it several times

    It's not to heavy but doesn't feel flimsy. The sleeves feel like a good length. Overall, it's just comfortable and fits great.

    Great shirt, nice weight

    This shirt is really comfortable. Very light weight and cool to wear. I also like that it has an anti-microbial treatment. I would have given it 5 stars, but it runs a little slim for my wide shoulders. Even so, it still fits me pretty well.
