Rated 4 out of 5 by from Great all-around casual shorts I've been buying these shorts for years. I'm short and the short inseam works for me. Also appreciate weight and quality. Preferred model when liner was black versus more recent white lining. I wish Columbia would make a narrow nylon belt that would fit through the belt loops on these shorts. Even with drawstring, they tend to ride down if you put anything in pockets. Belt would also dress them up a tad for golf, etc.

Rated 5 out of 5 by from Great for swimming Been looking for nylon swimming shorts for the quickest drying. This is lightweight yet nice looking shorts! Got the cool grey and it's a nice light grey color. Ordered size S since chart showed 32 waist. It fits but is tight with the elastic waist stretched out near max. Decided to keep it to use for the pool/beach but would been much more comfortable and reached for normal shorts duty if I had gotten a M. Maybe I'll order M in another color when on sale, since my waist only seems to be going one way lately.

Rated 5 out of 5 by from Lightweight material I bought these for my son to wear while fishing and he says they keep him cool and dry quickly. He's asking for another pair in different color, so I'm guessing these were a win. However, just to note they do have the mesh liner like swimtrunks....that's the only part he wasn't crazy about.

Rated 5 out of 5 by from PFG Backcast water short I first wore these shorts while working with kids at a summer camp that was on the coast. They hold up great in swimming pools and salt water as well as our rivers and lakes. I find them comfy enough to want to wear all the time so I ended up cutting the netting out and just wear compression shorts with them if I go swimming. They dry very quickly even with this method. I have three pairs now so I pretty much wear them everyday. Once these pairs run their course I’ll probably get the 6’ versions so they sit a little higher on the quads. Overall I love these shorts ans I wear them daily to prove it. If you want to give someone an awesome gift or just do yourself a favor, pick yourself up a couple of these and you won’t ever look back.

Rated 5 out of 5 by from Popular with teen boys Purchased almost every color for my slim teen boy. He loves them! We cut the lining out as he prefers to wear his boxer briefs instead of the mesh liner. I think they should come in an xs for super slim guys too!

Rated 5 out of 5 by from Quality shorts My two boys that are 16 and 14 love these shorts. They are so versatile weather you are swimming or fussing on the boat to every day casual wear. They wear them all of the time. The variety of colors help them to match any kind of shirt. Also the quality of the material helps them to hold the color and durability for a long time

Rated 5 out of 5 by from Great shorts This the second batch of these shorts I've purchased. I got the II version a couple of years ago and wore them all spring summer and fall. The elastic is wearing out so I purchased 5 more pair of the III version recently. I've poked holes in the pockets, but they have never ripped. Not sure what was changed between the II and III. These are great shorts for the Houston summers.

Rated 5 out of 5 by from Top quality shorts Bought these to wear as casual shorts and I am extremely impressed. Very comfortable and fit perfectly. They're also very durable and will be great for any work or outside activities. Cutting out the mesh liner improves the comfort in my opinion. Definitely going to buy more in different colors, well done again, Columbia.

Rated 5 out of 5 by from These shorts fit all needs and look great I purchased these shorts because I heard they were good for casual wear. I didn't realize how comfortable they would actually be until wearing them. I've worn them for casual wear at work, outdoor activities, and I'm excited to try them in the pool. I would highly recommend this product.

Rated 5 out of 5 by from One great short. I am a tournament bass fisherman. I fish the Colorado River chain of lakes. Mead, Mohave, and Havasu. This part of the country gets hot. The Backcast III Water Short is the ticket. Light weight, comfortable, and dry's quickly. I can jump in the lake cool off and keep going. It's my go too shorts for being on the water seven months out of the year. Lots of colors to pick. Highly recommended.

Rated 5 out of 5 by from Favorite shorts of all time These are by far my favorite shorts I’ve ever worn. Perfect length, light and cool. I wear them fishing, to the beach, out to dinner, whenever. Very versatile shorts and I’ve had yet to ruin a pair. As long as they keep producing these shorts I’ll keep wearing them.

Rated 5 out of 5 by from My favorite shorts! These shorts are my favorite shorts by far! I put these through some harsh conditions as a fishing guide and they hold up very well. Not only are they very comfortable, but they look good as well. I wear a 38 in waist and the XL works fine. They are actually a little big but the draw string makes them perfect. Highly recommend!

Rated 5 out of 5 by from Quality shorts for everyday activities. I ordered 3 pairs of these shorts in the colors I like because they are so worth it. This is the second time I've ordered these shorts in 4 years because they are living up to my expectations. After putting my new ones next to my older ones, I am finding no fading, change in size or any wear and tear. I live in the Pacific NW and wear these everyday, even indoors in he winter. I'm a tee-shirt and shorts guy and I just love these. Obviously, I step it up on the golf course, shorts-wise, but these are definitely everyday shorts. I love the Omni Shade treatment to keep the UVs off me. I'm a 32 waist, so small fits perfect. I also like that there are two lengths to choose. I hope these are a Columbia staple for life!
