    Comfortable, lightweight, and very practical
    Size: 40, Color: Black
    These Vcansion cargo shorts are extremely comfortable and easy to wear. The cotton fabric is lightweight and breathable, making them great for warm weather. The loose fit gives plenty of room to move without feeling baggy or sloppy. The multiple pockets are a big plus. They’re well sized and actually usable, which makes these shorts perfect for casual wear, travel, or working around the house. They sit comfortably at the waist and feel well made for the price. If you want casual shorts that are comfortable, functional, and versatile, these are a great buy. I’d definitely pick up another pair.

    ​Best lightweight cargo shorts I own!
    Size: 34, Color: Black, Size: 34, Color: Black
    These are my new go-to shorts for summer. The cotton material is breathable and feels great—you barely notice you're wearing them. I love the classic look and the practical design; the loose fit allows for maximum comfort and movement. All of the multi-pockets are sturdy and well-sewn, making them perfect for camping, fishing, or just relaxing. They hold up perfectly in the wash. Excellent value, fit, and utility

    Online vs Instore
    Size: 40, Color: #01khaki
    As to be expected, not seeing and touching before purchase. I bought three pairs of these shorts in different colors for a trip to see my son graduate from his Army National guard AIT. I would rate the overall a five based on fit, quality, and comfort. One thing that I have to mark down, is they have elastic waist bands as described! In the description pic's, they are shown with nice long tie strings. The reality of what I received is the stings are too short to tie. They were almost the same circumference as the waist band, so only able to tie in a small knot, rather than a bow. no Biggy, until it's time for the restroom. Hopefully it's self explanitory....fumbling around with a knot! waist fits as stated to my size, but add weight of wallet and cell phone, and after a few steps, they begin to slide down. Tie string a must. I will see about finding something longer, as I do like them overall!
