T-shirt guy
Coming from a guy who has well over 300 T-shirts I have some that cost $100 some that cost $150 something that cost $10 but I will say yours has to be the most comfortable shirt I have ever worn and I’m not the suit and tight dress up collar worker and a T-shirt and jeans and some cowboy boots and I’m good but I’m about ready to clean out my wardrobe and purchase some more undrdog shirts for sure
Overall great, not sure of the purpose of the interior fabric “wings"
Great product. Material is nice but not as soft as some organic blends I’ve worn. Heavy weight fabric is great but feels a little warm in the summer. Mostly wearing for sleep shorts at night when it’s cool. There is a design element I’m not sure about. In the front at “wings” of material. Unless you spend time adjusting, they don’t do anything for me. Prefer a u-shaped pouch for support without the added fabric.
Underdog for the dogs
I'm a full time dog walker and wanted a bulletproof shirt that could handle the elements, drool and claws! Not to mention one that isn't actively poisoning my body. This shirt has met every promise and when a company offers a lifetime guarantee I know they really believe in their product which gives me a ton of confidence in my purchase. Thanks Underdog! From me and all my pups!
Multi item
I have the underwear, the t-shirt and the polo, I love how the items pull the moisture from you if you go into a cool room you will get cool fast and the items are comfortable to wear. The only issue I have is with the tee shirts is the neck line that’s why I started getting the polo’s for the v in front.
good t-shirt for real life
These Grey(s) are my second foray into UndrDog. Finally narrowed down my ideal size (M) for a PROPER undershirt fit, under PROPPER work clothes. Still enjoying my previous Large Black T-shirts, outside work in this (90)+ degree summer heat we're "enjoying" in Denver right now. Been awhile since I've enjoyed purposefully dressing. Thanks, UndrDog...

I I’m not a fan of these shirts. I feel like they’re poorly made. I feel forever crooked in them. The shirt is not straight. The weave comes from upper left to lower right I can’t find out how to communicate through the app here. I know I’m technically outside of the return window, but these are unbearable for me.
These shirts are very lightweight. I sized up but should have stuck with my size. They are a little loose by sizing up. They have a good fit and we will see about the durability. Jist know when they say strong, they do not mean heavyweight. They are almost see through and the lightest weight shirts i have ever owned. Hopefully they are a lifetime shirt.
Thought this was a great t-shirt
I received my t-shirts 2 weeks ago, I thought these are really nice shirts. I have been washing them in cold water and hanging them to dry on a rack,and this morning I put one on and the side seems are coming apart. This is a lot of money for something that falls apart after 2 weeks. Would not recommend or buy this shirt ever . I would like to send these back and get my money back!
Never got my order
I reached out twice about not receiving my order. Tracking showed it staying in one spot for over a month. I sent screenshots of the tracking both times. The only response I get is we will look into it. Then I never here back about a follow up. Have asked for a refund. But still no response. Only a chat bot response saying they will look into it. It's been over a month... tracking ha made no progress.
