Size Guide

Your measurements will be most accurate if someone else measures you. Make sure your feet are directly under your shoulders, and let your arms hang down by your sides (see photo for reference). 


Measure the circumference of your chest at the fullest part. Under your armpits, around your shoulder blades, and around the front of your chest.

Measure the circumference of your waist at your natural waistline. If you bend to the side, the crease that forms is your natural waistline.

Measure the circumference of your hips over your hip bones and around the fullest part of your buttocks. Please do not use your "pant size." The actual measurement will be more accurate. 

Use the chart below to determine your size. If you're on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. If your measurements for chest and waist correspond to two different suggested sizes, order the size indicated by your chest measurement.

XS 33" - 35" 28" - 30" 34" - 36"
S 36" - 38" 29" - 31" 36" - 38"
M 39" - 41" 31" - 33" 38" - 40"
L 42" - 44" 33" - 35" 40" - 42"
XL 45" - 47" 36" - 38" 43" - 45"
2XL 48" - 50" 39" - 41" 46" - 48"

What a great idea this is! I was actually in Denver at a baseball game using the backpack and when the sun went down it got really chili but I had a sweater in seconds, buying my whole family one, everyone needs this

Heavyweight zip up

Very happy with my purchase. It is a very well made sweater. The hood is thick and holds its shape. I’m 5’ 11” and about 188lbs, I bought a medium and i think it will work well for me. I probably could have gone up a size and got a large but I was afraid it would be too baggy. But now that I have the sweater, it’s so nice that I think I’m going to take the risk and buy the large also and compare them both. Either way, I’ll keep both sizes because I’m very happy with the construction.

Only hoodie you’ll ever need!!

Beyond excited about my new hoodie which I bought as a birthday gift for myself. I got the heavy weight since I get cold easily. It surpassed my expectations. Great material, great fit and super cozy. Not to mention the functionality! Can’t wait too blow people’s minds and convert them into the Quikflip/ hero hoodie family!! I’ve already placed my second purchase for my wife after I showed her my “magic trick” lol she instantly said “I want one!” Thank you Rener! And thank you to the rest of the Quikflip team! :D
