Always an adventure.

When you babysit for your nephew, there's no telling what the day will entail. Wear the Mammut Men's Alvra Short-Sleeve Shirt, and you'll be comfortable whether you're pretending to be a troll at the playground bridge or running from monsters in the backyard. The lightweight fabric is soft and breathable, so you can make your escape without overheating, and it's rated to UPF 50+ to help protect you from the exposure to dangerous rays. Its button-up style is classy enough to go from making PB&J's to meeting your friends at the pub when your shift with the kiddo is done, and the FreshTech treatment helps you get there without the smell that comes from playing all day.

  • Button-up shirt for long days of fun
  • Soft material is breathable and wicking

Not slim fit

  • Fit: Runs large
  • Size Bought: medium

It's a nice shirt, but I wouldn't call it slim fit. The chest and shoulders fit nicely, and then there is a ton of extra fabric around the stomach. The material was also thicker and stiffer than expected.

Slim fitting shirt for warm weather

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

This shirt runs true to size but it is slim in the body and the arms - especially the arms. It is attractive, comfortable and breathes reasonably well. It has first-class stitching, buttons and the material looks like it will last. No wrinkles if you dry it a few minutes on low and hang while still damp. I have worn it only casually so I can't comment on the worn-for-days redolence.
