    Once you put them on, you will know you made the right decision
    Size: 38, Color: Medium Tint Denim
    Absolutely perfect in every way. Staring either the very reasonable price, the true to size fit, and quality. Hip pockets are deep, and can come in handy. Most don’t know that Wrangler actually started in 1904 as a company called Blue Bell, and later renamed Wrangler. Well established and a long history of top quality clothing. Although you may find another company selling for a bit less, that’s what you’ll get……Less !!?

    Good shorts but they run big
    Size: 38, Color: Dusty Olive
    I've been losing weight and picked these up in my new size (38). It turns out these are cut for a generous American midsection, and have an elastic fit in the waist, so you can (and probably should!) safely go down a size. I got mine in 34 instead and they fit great.

    Great fit, functional, most comfortable shorts!
    Size: 30, Color: Anthracite Camo
    These are my go-to shorts, I now have five pair in different camo colors! I suggest one waist size smaller than you normally wear, (I buy a 30 instead of a 32, because they stretch and would be too sloppy if I purchased my regular size). The large open slotted pocket on the left, behind the Velcro flap pocket, is perfect for a normal sized cell phone. Plenty of utility pockets for EDC. Since these stretch slightly to accommodate movement and sitting, they are extremely comfortable. Also, my wife says they are good looking on me, so that gets an extra star!

    The perfect throw-on athletic dress (with built-in shorts!)
    Size: Small, Color: Navy Blue
    I’ve been loving this athletic dress—it’s one of those pieces that’s both functional and cute, which is hard to find. The fabric is lightweight, breathable, and slightly stretchy, so it’s comfortable whether you’re running errands, going for a walk, or just chasing kids around all day. The built-in shorts are a huge plus. They stay in place well and make it feel more secure than a regular dress, especially on busy days. I also appreciate the pockets—they’re actually usable and don’t feel bulky. The fit is relaxed and flowy, which I personally like because it’s easy and flattering without clinging. The straps are adjustable, so you can customize the fit a bit depending on your height or preference. I’d say it runs true to size for a looser fit. If you want it more fitted, you could size down, but I like the casual, sporty look as is. Overall, this is a great everyday summer staple—super easy to style with sneakers or sandals, and perfect for travel or on-the-go days. I’ll definitely be getting more colors!
