I have quite a bit of UA (and Nike Dri-Fit) gear for hiking, camping and general workouts. My inventory includes Heat Gear t-shirts/compression shorts and Loose Gear shooter shirts.
usually a medium sized shirt is tight on me, and a large one is comfortable but not too baggy. anyone who knows about the sizing please help
I strongly recommend you visit the Under Armour website and click on the specific style of UA gear and check out the "sizing chart". This is because the sizing will differ between types (e.g. Heat Gear vs Loose Gear) but also within the same type (e.g., Heat Gear medium t-shirt is for chest size 38-40 but Heat Gear compression short "medium" is waist size 30-32 -- normally "medium" is waist size 32-34).
You might want to let us know your measurements so people of comparable size can let you know how UA gear fits.
anyone know how the tight shirts are? i dunno if i should get tigt
ones or loose ones. both would fit my body type
I'm a size 38 jacket (although the tape measure says 40" chest, I like the way the size 38 jackets drape so I buy those instead).
My Heat Gear (size M) t-shirts fit rather tightly. They're supposed to do that -- the idea is that they act as a "second skin" to wick away moisture. While they are tight, it is not restrictive.
However, YMMV as it depends on your body type. I think overall body type is more important with the Heat Gear line because if one's waist is on par with one's chest measurements (or in some cases, larger) then the compression caused by the tight fit may become uncomfortable. For me, I have a 28" waist and even that difference (12" from chest to waist) is not enough to make the Heat Gear shirt fit loosely around my waist -- it's still tight, as intended. Keep this in mind when sizing.
My Loose Gear (size M) shooter shirts fit VERY loosely. I'd say equivalent to wearing a size L cotton shirt (unshrunk). I compared the UA Loose Gear size M shooter shirt to my Nike Dri-Fit size M shooter shirts and the UA shirts are significantly looser.
Note: if you decide to buy, check out Lightfighter as Skunk said. They sell UA "tactical" gear, which means the logo is subdued for use by operators. Were you surprised when Skunk recommended Lightfighter? Didn't think so. It's tactical!
Anyway, not only do they have the tactical line, they're also the cheapest place on the 'net to get UA gear. UA generally does not discount off list so most places sell at list. Lightfighter sells at below list -- e.g., a "normal" Heat Gear t-shirt is $25 while Lightfighter's is $19. However, be aware that Lightfighter is in short supply of UA tactical gear (my latest order has been waiting for around 4 weeks) due to heavy demand of our forces in Iraq.
HTH,
