As many other reviews said, these Columbia Women's Full Leg Roll Up Aruba pants run small! The Arubas are definitely very snug/tight in the upper part (waist and butt), when compared to my Columbia Women's Cascades Explorer pantsColumbia Women's Cascades Explorer Pant, Black, 16/Regular which also runs small, but not as small as the Arubas! I sized up one size, to size 16 for the Cascades and thought it would be the same for the Arubas. However the Arubas are much tigher in the waist, and longer- at least 1.5" longer (see photos) in length. I'm a medium/large build, about 5'6" tall and will have to hem the Arubas. Also in comparison, these Arubas were much tighter/snug in the waist (and longer) compared to the same sizes for Royal Robbins Discovery, Ex-Officio Nomad and some REI pants. On the positive side, the Arubas fabric is similar to the Cascades, so I assume they'll dry quickly so great for travel laundry and also lightweight for luggage/packing weight. The colors offered are also practical/easy to match, no weird bright green or yellow colors. The feature to roll the legs up to capri length are also better looking than the "zip off leg" style which looks too casual and bulky in addition to the possibility of losing the zipped off leg pieces or fading/wearing unevenly. The other plus is that these Aruba pants also has an extra front zipper pocket on the thigh, just below the one near the waistband, perfect for cell phone, passport or securing small items. This thigh pocket is just large enough to fit a Samsung Galaxy S7 Edge with a case. A passport would fit since it's not as tall as the Edge phone. For my travel pants I want that secured, front thigh pocket-essential to keep my cell phone in, much easier than trying to pull it out of a purse or backpack. And it's very difficult to find women's travel pants with this pocket feature. When will these clothing companies finally figure this out??? Anyways, the lightweight, quick drying, and large enough for my cell phone secured front thigh pocket works ok for me during travels. Just wish that the waist was more comfortable and Columbia was more consistent in their sizing, so I'd give them 3.5 stars. If they would fit better or more consistently then probably 4 to 4.5 stars. And of course offering more practical women's travel clothes with the features we need. So with these Arubas definitely size up, one or even two sizes, depending on your body curves. And possibly need to hem, although this length is probably good for the taller persons.
