this worx for me ,,but didn't when I was skinny as a whip yrs ago ,,.back then I was jeans under coveralls ,preferred lite til it got dam cold so I could work , most times a thermal zip hoodie and by all meamns a hat ,,.. one with earmuffz is nice in severe cold ,that workt good for 10 hours outside doing home improvement and construction /hog farming ,. BUT TODAY I AM A ROBUST 250 hunk LOL,, so this worx best for me t shirt ..boxer shorts or sweats under denim bibs with a hoodie over all that ,, I can move good in that and keep warm if the wind aint mean or above freezing ,. I have serveral insulated coverall bibs for the cold weather ,. and lots of heavy plaid zip hoodie heavy shirts ,, a windbreaker over that is nice for auctions or roading tractors ,, I also have a firemans heavy weather coat to keep the weather off me in crazy wether rain . snow sleet ,. but that thang weighs nearly 10 pounds.. also have slip in cheap boots ,,. and add sox for the cold , my feet stay dry and therefore warm , summer time I prefer slipon older street shoes ,,. my feet stay comfortable and don't sweat like they do in lace up work shoes ,and I don't spend a couple minutes grunting to put theshjoes on and lacing them up theslip ons will come off easily by latching the heal on a step and lifting my foot out ,,. and I can march thru 6 inches of cow dupe without them coming off too ,,used to hate to get my hand s grimey getting work shoes off or fighting iced up shoe laces for 5 minute s.all the while my feet were froze and or wet ,, . I can jump in and out of all this in a couple minutes ,, and that's what I like ,, yes I have spent a hundred bux plus for good dry work shoes , but was soon saddened when a sumthing puncturesd thru somewhere and violated the dry with water ,, so much for that hundred dollar pair of shoes because ,, my worksessionsoutside in winter time are 3 hours in the morning ,, followed by a 2 hr lunch /mail / phone calls / research at noon and build fires ,,. then out again til dark,,. without the hour or more warm up at noon my plan to stay warm falls apart ,,. feet get cold ,, t shirt gets sweaty and wet from physicalmovement ,,,I always change out wet clothes .. failure to do so is a recipe for a cold ,.although I have crackt and split the rubber boots in the severe cold ,,. for another 12 bux at tractor supply I am good to go ,,. and I probably buy 1or 2 pairs a year and have taken a utiliy knife to the calfs topps andmade them into hi tops for summer wet weather work . I do have nice steel toed and also a pair of leather decent work shoes ,, but rarely wear them unless the demands of the day require it ,,.
