Men's Zero Rules™ Short Sleeve Shirt is rated 4.5 out of 5 by 60.
Rated 4 out of 5 by from Excellent Performing Shirt - slightly large I bought this shirt based upon reviews without trying it on. In other Columbia apparel I wear a medium - although medium can be a little large on me. I found the fit of this shirt to be pretty similar to other Columbia's mediums - that being, a little larger than medium. This shirt isn't their "Active" fit, so don't expect a form fitting shirt. The medium is a little larger than I would like, however, for summer outdoor hot/sweaty shirts, I think it will work. However, I probably will not wear it as a fashion shirt. That said, I'm not sure a small would fit any better. The fabric tends to hang in odd places on my body. Overall, I think the shirt is an excellent value at a sale price. I'm not sure I would be willing to buy it at full retail.

Rated 5 out of 5 by from Great Warm Weather Shirt This is a wonderful shirt for those hot days. Fits great, keeps you cool and dry. I had 2 of these shirts which I wore in the summer in both Disney World and Las Vegas. Have since bought another one. I would recommend this product.

Rated 5 out of 5 by from Breathed in Africa This shirt served me well on my recent safaris in Africa. October is the hottest time in the Okavango Delta and I was as cool as could be in this shirt.

Rated 5 out of 5 by from As if it's 5-10F cooler... Based on the name of the fabric, I'd (skeptically) hoped for a wonder-material that somehow feels cold even in the heat. For me, that was not the case, but I was pleasantly surprised. I put this to the test by playing tennis on a sunny, 90F day with 65% humidity and hardly any breeze. Of course it was hot outside and I was sweating profusely. My uncovered arms and legs felt hot. Under my shorts, socks and tennis cap, I felt hot. However, my upper body was reasonably comfortable...not cool, but not hot either. It was like my upper body was playing tennis on a day that was 5-7 F cooler. The cooling effect works better if there's a good breeze...then maybe feels like 10 F cooler than ambient. One other unexpected benefit. After tennis, my shirt is usually soaked with sweat so I take it off and change into a dry t-shirt for the drive home. I often have to wrestle and contort my body to remove a soaked shirt since it sticks to my skin. However, even when wet, this shirt lifts off of skin easily and can be removed with minimal effort. For the above reasons, I bought a second shirt. Up to this point, I've been buying synthetic tennis t-shirts from Adidas, Nike and Under Armour. Those are still nice products, but if I know it's going to be really hot outside, I'll reach for my Omni-Freeze Zero shirt.

Rated 5 out of 5 by from So far, so good After several weeks of using this shirt on my rowing machine outdoors in Arizona in the summer, I have to say that it is all it's cracked up to be. The material is comfortable. The shirt sizing is accurate. It has come through 20+ washes just fine. And yes, it is a lot cooler than a sweaty cotton t-shirt.

Rated 5 out of 5 by from My husband's go-to everyday shirt This is a perfect all-summer-long, easy-to-wear, easy-to-launder shirt for my husband. He wears it to work out or for a run to the hardware store, for home office work or to relax on the patio. It wicks to keep him cool, and it's comfy without an undershirt. He has several of this shirt. The only issue is that it is easily snagged, so it's not for wearing under a day pack for our short-to-mid-length hikes.

Rated 4 out of 5 by from Great shirt but..... Love the shirt, however within a month both the "logo" and the "C" on Columbia started peeling off. Bought 5 shirts and so far the other 4 are doing OK so I'll watch and see how they hold up.

Rated 5 out of 5 by from Perfect I was looking for these types of shirts for the longest time but never had any luck with them. Other brands would be too short/tight on the sleeves, shoulders, or stomach area, too thin, too thick, etc. These are perfect. Great material not too thin/thick, perfect length in the sleeves, and general overall fit. About the fit, however, they do run large. I bought large and medium based on the reviews here and returned the large as the medium fit perfect with just enough room to not have me go the size up. So happy with these I bought up every color I could find!

Rated 3 out of 5 by from Not thrilled Bought on premise that the shirt will use sweat to cool my body by 10 degrees and I feel no difference in this shirt and any other shirt. $30 wouldn't be a bad price if it held to its claims.

Rated 5 out of 5 by from This shirt really is designed to keep you outside! I live in a high desert so being outside for extended periods can be challenging given the heat and sun intensity. I purchased two of these shirts in black and grey. I've had these on in 90+ degree heat at altitude as well as at sea level and both kept me cool and outside. Since I have purchased one in each color and naturally the lighter colors are a bit cooler, but only a bit. This fabric is amazing stuff. One side note though I walked into a grocery store from 93 degree heat and absolutely froze in there, so take a fleece - no joke. The fabric pulled all the heat off my body it was trying generate to balance its self. Beyond that this T worth having as a summer go to shirt.

Rated 2 out of 5 by from If you like a tighter fitting exercise shirt, look elsewhere Never fails. Companies get it just right with a shoe, shirt, or shorts and then decide to change it. Columbia had it *just right* with their old Titanium shirts. I bought quite a few back in 2010 and I STILL use them...and I have been really tough on them. Perfect material, strong, but lightweight and most importantly a great fit. These shirts are definitely not Titaniums. They run really big. OK for an outside shirt that you like a little loose I suppose. I attached a pic showing one of my old Titanium shirts (red) laid on top of the new Zero Rules shirt. You be the judge. I bought two of these shirts, but I will not be buying more. If Columbia brought back the old Titanium shirts, I'd probably buy 20.

Rated 5 out of 5 by from Best shirt out there I own 8 of these shirts, both short and long sleeve. They are hands down the best shirts I have ever worn. They don't stretch or loose shape after repeated washings. They don't retain odor after working out. They dry fast. The logo stays put and doesn't peel off. I haven't been able to find a shirt that fits as well as these or keeps performing in everyday use, from work to workout, then to weekend hiking. PLEASE COLUMBIA DON'T EVER STOP MAKING THESE!!!!

Rated 5 out of 5 by from Keeps you cooler in hot weather While training for a 13 mile paddleboard race in SW FL; I was constantly battling 90 degree heat and 70% humidity and overheating was a constant concern. After wearing the shirt; I noticed a substantial difference in my body heat and ability to push through the race without being extremely fatigued in spending 3 1/2 hours in the heat in the race. This definitely made the difference in my ability to perform and I would recommend this product to anyone who is an endurance athlete and needs cooling abilities

Rated 4 out of 5 by from Very Good Product: To Whom It May Concern, I was asked for my review of your “award winning Omni-Freeze Zero” shirts that have the following sweat activating gel packs, omni-wick fabric, and omni-shade 30 UPF fabric. During this summer when I wore it, the 7 Omni-Freeze shirts + 1 PFG (sweat activating gel packs / omni-shade 30 UPF fabric shirt) shirt I purchased performed up to their standards. I felt cool when I began to perspire, and left me feeling comfortable and drier than had I not wore those shirts. From that perspective that they made me feel comfortable during hot and humid days, these shirts are everything I could have hoped from them. Absolutely lives up to Columbia’s advertisements. I would also add that after normal cleaning and drying, that they still perform as advertised. Now I’m going to tell you why I’m not going to purchase any more until this is corrected:. They don’t have pockets. Now this may not seem like a big deal, but there were soooo many times I normally would have put a pen or a my hotel card in a shirt pocket……………..but I didn’t have a pen to write down something important, or if I had a pocket, I would have immediately put my hotel card in my pocket – instead of being locked out – yes, this happened. No pocket equals no purchase…………… Now this isn’t a make or break, but how about adding some more colors? How about brown and or burgundy? Dark colors versus white or light colors – because white shows the blue gel pack rings when activated. Or how about producing the typical white V neck under shirt gel pack T-Shirts? Omni-Freeze Zero shirts are a great products. Hopefully you’ll start producing them with pockets so I can purchase more of them. John

Rated 5 out of 5 by from It works. This shirt keeps me cool. I forget I'm supposed to be hot. I marked "true to size". But who knows? I got an extra large and it fits me the way I want. Size depends on what you want. Will be getting more for next season.

Rated 4 out of 5 by from Zero Rules Short Sleeve T I purchased this shirt in a large and if you are looking for a great shirt that will keep you cool and fit comfortably then I recommend this shirt. The sleeves a a tad bit long for my personal liking, but not to the point where its a make it or break it. Overall a great shirt. You can probably find similar shirts that do most the same thing for a bit less money, but if you don't mine spending the extra buck than this shirt will live up to its potential. I have only recently purchased this shirt so I cannot comment about its overall durability yet.

Rated 5 out of 5 by from Comfortable Very comfortable and surprisingly warm. Not a thermal base by any means, but distinctly warmer than two other Columbia "cooling" shirts I bought. Its nice to have this as a base layer offering a little variety over the other synthetics' feeling of cool.

Rated 3 out of 5 by from DON'T GET THE WHITE I like this shirt a lot so I got it in multiple colors, including the white shirt. But what you don't see in the picture is the little "cooling" beads or whatever they are can be seen through the white. So instead of it being solid white, it looks like a white shirt with blue polka dots. Wish the picture was correct!

Rated 5 out of 5 by from Just what I needed!! I have a neurological illness that prevents me from sweating and therefore my body overheats easily. My wife bought this shirt for me hoping it would work to keep me cool. I wet the shirt in the sink, wring it out gently, and wear it to play golf or anything else that is strenuous. It keeps my body cool and has been great in allowing me to have a more normal life.

Rated 5 out of 5 by from Good value and very functional This is my second Zero Rules shirt. My wife and I bought these for overnight hikes with limited laundry facilities. It's great to be able to hand wash them and be able to wear them the next day. Lightweight, durable, and comfortable. Great go-to shirt for active people.
