HUGE SPORTSMen's Splice UV Sun Protection UPF 50+ Skins Rash Guard Long Sleeves(HeyToucan, L)

Q: Would a xxl size be too small for me if i am 6ft tall, weigh 245lbs and have a 52 inch chest?

2XL would be just right if you're a "fit" 6ft-245lbs. I'm a 6ft-238lb full on "Dad Bod," (more "husky" than "overweight") and the 3xl is perfect for me. I prefer a slightly loose fit over compression fit. Hope this helps! (and made sense lol)

Q: Would this fit a woman5’1 130lbs ? Like the small ? I need rash guard for jujitsu

This is what my husband got, I tried it on. I am 5'2" and a bit heavier. It is long on the torso and arms. I bought one of the women's large and found it fit pretty well. The torso of the women's large is a smidge loose, which I find comfortable. I still found the arms of the women's large long by an inch or two. I just roll them up some. This has been a great garment. It keeps you warm, when it is a bit cool and it keeps you cool when it is warm. I love mine and so does my husband.
