Slim Fit, but still a really great top

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

This one is definitely a slim fit. I am an XL and debating if I want to keep it or not. It would still be great for biking, running, layering, general cold weather activity, and it's Icebreaker, so it's just generally an awesome piece of clothing.

I also have an XL Ibex Shak Lite that might win over this one, but only on the basis of fit, and because I prefer a sightly more relaxed fit.

This one has some very nice details though... a more ventilated fabric panel on the inside of the arms, a double-lined hood to keep the cold out, three zippered pockets for keeping a key or ID with you during activity, thumbholes AND mitten cuffs (if you are unfamiliar with the mitten cuff... the cuff will fold over to create something of a "mitten" over your hands when it's cold out, or if you just need that extra warmth for the beginning of your run, and pull it off as you get warmed up, or maybe you go up in elevation during activity and just temporarily need the protection, then you don't need to carry gloves with you). Love that feature!


Keeps me warm!

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

I love this hoodie - wear it on ski patrol everyday. Breathes well and keeps me nice and toasty. I wore a similar Icebreaker top for over 300 days and my only complaint was the wear on the sleeves that developed (slowly the cuffs would fray) but for being a wool product and used a crazy amount, I think this is normal. I still give it two thumbs up!
