Rated 5 out of 5 by Nice Trunks Good looking well made swim ware. I have a 33" waist and size Medium fit perfectly. Going to buy another. February 18, 2014
Rated 5 out of 5 by Swimmung trunks Good look, quality and fit. January 12, 2014
Rated 4 out of 5 by Water-Works Dries very fast and they are very light, but the pockets come inside out a lot while trying to swim. Needs more netting in pockets for water to pass through. December 14, 2013
Rated 5 out of 5 by Best buy I have worn these before and they wear like iron. They are comfortable, functional and all round the best I have ever found. Living in Florida we are presented with all kinds of shorts/swim merchandise. These are by far the best in any category. You can't go wrong buying these. November 2, 2013
Rated 5 out of 5 by These are the best shorts This is the 3rd time I've bought these shorts for my husband, he practically lives in them....they are cool and dry quick......and look good......I only wish they were resistant to bleach as my hubby has ruined 3 pair this way, but he still wears them. September 10, 2013
Rated 5 out of 5 This product is perfect. I never take the time write reviews, but I love these shorts so much. I wear them swimming, running, and out to parties with a button-down. They are so versatile. August 27, 2013
Rated 5 out of 5 by Love! I bought these for my boyfriend and they fit him perfectly. He loves them! I got them for him in the Sail Red and they're great for the rest of the summer July 23, 2013
Rated 5 out of 5 by Great Product Perfect shorts for the water. I usually cut the liners out of shorts like these but the liner in this pair does not ride up. They also dry quickly. July 10, 2013
Rated 5 out of 5 by Backast II water trunk great! Excellent product, very light weight and comfortable, dries very fast. July 2, 2013
Rated 5 out of 5 by Husbands Favorite Suit... So we bought 3 colors! I first got these for my husband as a gift. They are very flattering to his build (small, but with somewhat wide hips) and they are a little bit shorter than some of his other swim suits. Sometimes less really is more! He usually wears a size 31 waist in men's pants and the small fits him perfectly. The quality is excellent and the colors haven't faded. The suit is thin, so it drys fast, but it is thick enough to give good "coverage". Husband loves these shorts and I love them on him! We will probably buy a few more, even though we already have 3 colors (black, cypress, and riptide). Oh, I must mention the price - $30?! VERY reasonable price for the style and quality you are getting with these shorts. Makes us want to stock up! June 15, 2013
Rated 5 out of 5 by Backcast water trunk These shorts are well built and an excellent choice for the water . I wish they were sold in Canada or shipped there . June 6, 2013
Rated 5 out of 5 by oldies still goodies My husband has been wearing these shorts for years. They are always the same quality year to year. They are all purpose. Fishing, yard work, shopping, traveling, and anything else you can think of. If traveling they rinse out easily and are dry by morning. They wear well and the color doesn't fade. Highly recommended. April 6, 2013
Rated 5 out of 5 by Beautiful Upper Thigh Tan I can confirm that your thighs will be grateful for these shorts. Less importantly, they're comfortable, lightweight, durable, and the ladies love them. April 4, 2013
Rated 5 out of 5 by Thigh Tan These are some top notch shorts right here. I can remember the last time I bought a pair of shorts that gave me this good of an upper thigh tan. 10/10 Would recommend. March 5, 2013
Rated 5 out of 5 by Love Columbia Water Trunks My 15 year old grandson loves Columbia water trunks. In the spring and summer we purchase them at Bass Pro Shops in Nashville. This is my first time to order them online and I'm very pleased. My grnndson particularly likes the carbon color. I ordered medium this time since he is very slim but still growing and I wanted some growth room. Typical GRAM. January 5, 2013
Rated 5 out of 5 by excellent shorts I've worn earlier version of these shorts for 9 years and extremely impressed how they've lasted. My older pair was size medium so ordered same size again without looking at sizing chart. Of course I needed to exchange for size small which fits fine and matches todays current sizing chart. I've worn these shorts mainly for just knocking around. They're very comfortable and stylish for casual dress. My 9 year old pair have worn like iron and this newer version seems to be same quality with addition of belt loops (superfluous in my opinion) and narrow pliers pocket (also superfluous). I see some reviewers use these shorts as swim wear, where they will function, but I've worn them mainly as comfortable casual everyday shorts. If you're in and out of water a lot these shorts will work great. Reference sizing: I'm 5'9" 148 lbs 31-32 inch waist and worn size med. for entire adult life of 40 years until recently. Now wear size small. December 24, 2012
Rated 5 out of 5 by good quality and features I had the older version of this product for the last 5 years and it looks almost as good as new. Ordered new version and looks and fits great-I use them for tennis and outdoor fun. December 12, 2012
Rated 5 out of 5 by Perfect Have 6 pair and might get some more. December 11, 2012
Rated 5 out of 5 by Personal favorite Good pockets, belt loops, fast dry, what's not to like? Usually wear xl but lg fits perfect. November 20, 2012
Rated 5 out of 5 by My college son loves them! He lives in these shorts and can go for days wearing them. Being and outdoor lover, these shorts take him everywhere. November 1, 2012
Rated 5 out of 5 by holds up to wear and tear and washing Bought for my husband replacing columbia shorts he has had for years and years. Every day, tennis, etc. Hopefully, these will last just as long....... September 19, 2012
Rated 3 out of 5 by Backcast II These shorts are great except the dark colors have white lining and they should be black. Also, the rear pocket is huge! Needs to be cut back in width and length. September 19, 2012
Rated 2 out of 5 by Unusual sizing Wear XL everything including earlier version of this product. This XL was at least XXL equivalent and had to be returned at extra cost. September 18, 2012
Rated 5 out of 5 by great fishing attire i wear these all summer long for casual wear around the place, we live on the river. August 28, 2012
Rated 4 out of 5 by Belt Loops? The belt loops seem out of place on this product and if they were to be used, more loops and a closer spacing would help their functionality August 27, 2012
Rated 5 out of 5 by awesome kayaking shorts very light, dries super fast ! i wear these while fishing and kayaking and really like them a lot. they have a drawstring and the mesh inner liners so you can wear them like a bathing suit and that is great on a hot day when you get out and wade a bit. August 26, 2012
Rated 4 out of 5 by Not really a bathing suit I bought this expecting it to be a bathing suit ("water trunk"). When it arrived, I saw a label on it that suggests it it made to be worn when fishing (or boating, etc.). It has belt loops, another hint that it's not a pair of swimming trunks. Unfortunately, I've gone on vacation and taking this with me as my only swimming trunks, so I'm forced to use it. I like how quickly it dries when I get out of the ocean -- the water beads up on it and falls away, but it's not as snug around my waist as I'd like. It does have an elasticized waistband, but not as strong or as wide as I'd like it. After this vacation, I'll probably just use them as camp or gym shorts and buy another bathing suit. August 15, 2012
Rated 5 out of 5 by Best swim trunks/shorts ever! There are the best swim trunks/active shorts I've had. The length is perfect for not getting in the way or sticking to you in very uncomfortable ways. Made of great, light, cool fabric. Very glad I purchased 3 pairs. August 14, 2012
Rated 5 out of 5 by Nice quality and perfect fit. This bathing suit fit perfectly and has a comfortable inner mesh. August 10, 2012
Rated 4 out of 5 by Great for everyday water activities These trunks fit great and work with low key water activities as well as those more intense days. They feel great! July 13, 2012
Rated 5 out of 5 by This is exactly what we wanted. Not like pedal pushers. Wondeful product. Pricey. Know that it will last. July 11, 2012
Rated 5 out of 5 by great for the water these shorts are very comfortable for use in the water and out of the water. They are well made. I would buy them again. July 3, 2012
Rated 4 out of 5 by Comfortable trunks Solid functional bathing trunks. Not sure need for belt loops. Fit and quality are good. Color is accurate as photo. July 3, 2012
Rated 5 out of 5 by Great Shorts I know these are called water trunks, but I use them for fishing, and for shorts in south Texas. They keep me cool in our hot humid climate and are easy to clean. I love the deep front pockets and the back zippered pocket. I have 4 of the colors and they are my number one go-to short for all occasions. Thanks Columbia for making such a great short! June 30, 2012
Rated 5 out of 5 by Fantastic and Active Shorts I have been buying the Columbia Backcast Water Trunks for many years. I wear them because they are functional, quick drying and last forever. I highly recommend them for any tropical or wet environment activity. June 10, 2012
Rated 5 out of 5 by This product is great The short are great, fabric are light and very comfortable. One issue M size are in fact L size. June 6, 2012
Rated 5 out of 5 by Best Trunk ever This is the best swim trunk I have ever owned. The fit is great, and they are extremely comfortable. I am on the water almost every day and they have held up to all the punishment. April 30, 2012
Rated 4 out of 5 by Pocket I love the shorts, however if you have an iphone with an Outter cover it will not fit in the smaller side pocket that seems ideal for the phone i am outdoors approx 300 days a year April 25, 2012
Rated 5 out of 5 by No complaints Fits and works just how I wanted them to. Great suit. April 24, 2012
Rated 5 out of 5 by Compfortable Fit These shorts have a perfect and compfortable fit. They are very fast drying and nice and cool on those hot days on the water. I am a full time fishing guide so these attributes are very important to me. April 21, 2012
Rated 5 out of 5 by Confortable This is my second pair of these. Great outdoor short for all kinds of activities. Highly recommend April 12, 2012
Rated 5 out of 5 by Swim Trunks Fits great and looks good too. Would definitely recommend this to others. April 11, 2012
Rated 2 out of 5 by shorts they fit weird around the waist, the draw string is thin and the elastic is flimsy, the inner liner is irritating while i sit. i am kinda particular when it comes to my shorts, had columbia shorts before and loved them but not these April 11, 2012
Rated 5 out of 5 by comfortable and easy to pack Great for swiming and boating. A real easy item to take on vacation since they pack in such a small space and dry quickly. April 8, 2012

Rated 5 out of 5 by Comfortable and fit well. I'm a full time guide who spends most of my time in the water (salt and fresh). So far these shorts have held up as well as my other Columbia products. Looking forward to many more years from them. March 9, 2012
