Loved the shirt. Fit was as expected, not too tight or loose. First time I wore it, after a few hours, I noticed that there were holes where the stitching was across the front of the shirt. Very disappointed as I really liked the shirt.

Ex Output:
negative

Ex Input:
This mask smells so bad like chemicals that I am not sure my son can wear it. We are trying to soak it in soap and water, but this is very disappointing. I would not recommend.

Ex Output:
negative

I am a novice at hiking or trekking. The poles are a prefect addition to my journey. They are easy to expand and fold away for another day in their own storage bag. I wouldn't leave on a trip without them.

Ex Output:
positive
