Men’s Declination Trail™ Short Sleeve Shirt is rated 4.3 out of 5 by 20.
Rated 5 out of 5 by from Best Shirt I ever owned Best Shirt I ever owned. I've wore it to work a couple hundred times. I've brought it on vacation to Hawaii, Mexico, Philippines, Florida and Las Vegas, and it still looks good. It is because of this shirt that I have become a loyal Columbia Customer.

Rated 5 out of 5 by from David I love this shirt it is is light, breathable and comfortable! I bought one last year and it has stayed the same size after 20 plus washes. This is a great shirt that is comfortable and great looking.

Rated 5 out of 5 by from Great shirt Great cost x benefit relationship. The mesh is absolutely light and soft, therefore nice for either outdoor, working or traveling experiences. Size is very comfortable and length, somewhat below the waist, is perfect and guarantees an elegant, casual fitting. Nice and careful finishing and light, pleasant green color. Should have bought more than one.

Rated 5 out of 5 by from Great shirt! I picked this up for my husband from the clearance rack at an outlet mall. He wears a L or XL, depending on the shirt. This was available is L, but it looked really wide! In the store, it looked like black and white (I got it in Grill), but once home, it's actually navy & light blue. I liked it even more then! It looks really nice on my husband, and he loves it! Looks like great quality of craftsmanship. Looks like it will wash up nicely.

Rated 4 out of 5 by from Comfortable and good looking shirt Yea, I like this shirt a lot. It is true to size. Looks like it did on the website. Easy care fabric and very comfortable for a warm summer day. I would give it as a gift and highly recommend it.

Rated 5 out of 5 by from Well...... I gotta say Columbia makes some very good products. But (DANGIT) with the countries that produce their shirts (Sri Lanka, Thailand, Indonesia) you never really know what size to get until it arrives in the mail. I ordered an XL based on my usual shirt size back in the states. I'm 5'6" and 180+ and broad in the shoulders. Thinking it should fit pretty decent based on others I own and have bought from them. Boy was I surprised. It was like wearing a tent! I love the shirt construction, pattern and color, but since I work overseas, I opted to sell it to a coworker and order a Large.

Rated 4 out of 5 by from Trail Shirt Good looking shirt. Selected it to wear on casual days at the office in summer. Only issue is length.5'10 with average build. Medium is too constricting at shoulders so I opted for the large. Fits better up top but the length is excessive to wear untucked. Washes and dries well, wrinkle resistant if you pull if from the dryer immediately.

Rated 5 out of 5 by from This product is just an awesome shirt all the way around! Bought one of these shirts for my husband in one of your retail stores. Have since purchased 2 more from your website. He loves them! They fit perfectly & are a comfortable & cool shirt. Can't wash them fast enough :) We have been very pleased with this particular product & will probably be buying more. Thank you!

Rated 3 out of 5 by from Fabric is heavier than expected The fabric weight is heavier than expected and I hope that does not become a problem here in the tropics. Also the fit runs big and the pocket design with the tab button is going to take some getting used to.

Rated 5 out of 5 by from Superb shirt Great quality, but the best part is that it keeps me cool in the burning Caribbean Sun.

Rated 4 out of 5 by from Nice material, but size is too big The material and fit is amazing, but I bought medium size and it is too big for me (195lbs and 6´1) .

Rated 3 out of 5 by from Seersucker Dimpled? The shirt is well made and looks good, but after the first wash developed a dimpled seersucker look to it which I can't get to go away except by a thorough ironing, which isn't at all what I was expecting. It isn't bad looking, but be aware the fabric may not stay flat.

Rated 4 out of 5 by from Great Shirt I wear this shirt all the time. It fits true to size. I would like to have had the top button just a little higher, however thats probably just a personal preference. The material is excellent, does not stick in hot weather...

Rated 5 out of 5 by from Very comfortable shirt I love this shirt. It is very comfortable and wears well for a long day. It does not wrinkle.

Rated 1 out of 5 by from Color is misrepresented I have 3 other Columbia short sleeve shirts. I bought this one based on the website pictures showing a grey shirt and the color listed as stone. When I got it, it is light tan with brown colored "checks" in the fabric. Not at all what I expected. I took it back for a refund.

Rated 3 out of 5 by from Large is too large The shirt is very roomy, which may suit some adventures well, but for just hanging around town, it is much too large for me. I am going to switch it for a Medium.
