My family and I have always enjoyed wearing natural fiber/cotton casual wear.  We've been wearing these 100% cotton elastic bottom jersey pants by Russell Athletic (and also by Champion) for many years. *Please Note: These are made from medium weight JERSEY/T-shirt type fabric (such as&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Hanes-Men-s-Beefy-T-w-Pocket/dp/B000CBV8PS/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Hanes Men's Beefy-T w/Pocket</a>) and NOT heavyweight fleece sweatpants!*

Likes:
>Nothing beats the soft feel of 100% cotton when dry except Merino wool.  We purchased the Navy which is 100% cotton; check with Amazon vendor about % cotton for the other colors.
>We use it for a wide variety of casual activities including lounging around the house/PJs, running errands around town, working out (weights/exercycle/running/self-defense/basketball/tennis, etc), gardening, walking the dog, 13 hour long international flights, you name it.
>Fabric is medium weight and is suitable for 50to  70F weather.  The ladies may prefer a heavier fabric for the same temperature range.
>Good quality construction/made in Honduras.  My NEW jersey pants came in sealed plastic bags with tags and don't appear to be seconds or irregular stock.
>The sizing is correct.  I'm 5'10" with a 32" waist and the Medium fits well.  My gal is 5'6" with 26" waist and wears the Small (it's hard to find women's 100% cotton casual pants with pockets).
>2 convenient side pockets for keys and other small items.
>Good quality elastic waist with a hefty drawstring.
>Elastic bottom to prevent hems from riding up and seals out cold air.
>Easy to clean: I use cold water with minimum detergent and hang indoors to dry to minimize fading and fiber loss using gas dryer.
>Amazon's price of $13.10 + free shipping is unbeatable!

Dislikes:
>Like all 100% cotton fabrics, constant washing and outdoors exposure will cause fading, slight shrinkage, and some pilling around the seating areas.
>Cotton is highly water/sweat retentive and feels clammy during hot/humid weather.
>The fabric only has average durability; it will wear and tear and fade over a year or two.
>Insufficient for temps below 50F; that's what heavyweight fleece sweatpants are for.
>Not much snob appeal wearing jersey pants in public but who cares; we're comfortable, efficient, and low profile.

Bottom Line:
It's great to find these 100% cotton Jersy Pants again after our last stash were gradually worn down and faded.  I ordered two initially just to make sure of the fabric and construction quality.  We were so pleased with these Jersey Pants that we purchased another five just to stock up!  Try them but make sure the medium weight fabric is what you want.
