Disclaimer regarding the following review: this is my first review and I'm very new to grappling. Please give me a break if you don't agree or if I'm missing something.
I've titled this a "Big Guy Review" since there seems to be a lack of reviewers that wear anything more than a large. And I'm sure there's a few guys out there who can attest to how hard it can be to find clothes, sports gear, shoes, etc.
I'm 6'5", 250 lbs. I wear a size 40 waist and my shirts are almost always XL.
Product: Under Armour HeatGear Compression Top
Purchased At: Scheels
Price: $35
Size: XL
I was originally looking at purchasing an actual grappling rashguard -- Sprawl Loose Fit, Koral, etc. I eventually settled on this because I didn't want to drop $50 (includes shipping) on something I've never tried on before. I went to Scheels and tried on a L and an XL. The L was way too tight but the XL fit pretty good. Or I should say it seemed to fit good for someone who had never tried on something like this before.
The first time I rolled in it I was really happy. Keep in mind I had been rolling in a t-shirt previously. I can't comment on how it'll hold up over the long haul but it's held up good twice so far. I expect it will do fine since football players use these and if it can hold up to a helmet snagging on it I'm sure it should do fine rubbing on a mat.
What I particularly enjoyed about this top was its heat-regulating features. Being a big guy I always have a hard time with my body overheating. It seems like I can never drink enough water. This top kept me so much cooler than my good, old cotton t-shirt and I didn't get the trademark heat-headache when I was done rolling.
The one downside is it doesn't have too much of a taper on the waist and this tends to make it creep up sometimes. However, this only happened once or twice and I didn't tuck it into my shorts very well.
Overall, I would recommend this as a cheaper rashguard replacement to a beginner not looking to break the bank on something they can't try on.
