Kill All Doubts Tee

Every rep is a battle. Every doubt is the enemy. The Kill All Doubts tee from Conquering Barbell is for the lifter who silences the voice that says stop and keeps going anyway. A fully armored knight stands victorious, the CB shield on his chest, sword at his side, holding the severed head of Medusa aloft in one iron fist. CONQUER arches above the framed graphic in distressed gothic lettering. KILL ALL DOUBTS runs beneath it in aged script. The cream and black palette gives it a worn, timeless quality that looks as good off the platform as it does on it.

Made on a garment-dyed heavyweight cotton tee for a broken-in feel straight out of the bag. The relaxed fit, lived-in texture, and vintage wash make it a go-to whether you are heading into a heavy session or walking out of one.

  • 100% ring-spun cotton, garment-dyed for a soft, worn-in feel
  • Heavyweight construction with a relaxed, oversized fit
  • Garment dye process creates a unique vintage texture on every shirt
  • Front graphic with premium print quality
  • Classic unisex crew neck and short-sleeve cut
  • Available in black

Every order is printed after you place it. Tees, tanks and hoodies ship in 7–10 business days (after the payment clears). Flags ship in 10–14 business days (after the payment clears). Weekends and holidays don’t count.

    THE BEST brand on the market hands down. Walks the walk and talks the talk. Amazing art work and design too. Fits perfectly and just like the guy above saying they abuse the shirts in the gym, same lol.

    “The perfect pump cover.”

    The relaxed fit one I got recently is the perfect pump cover/extra layer for me. In Alaska the gym can feel cool at times and I hate being cold when I train. Mississippi boy. I just order 3 more. CB versus erbody

A little help with the fit

Find your fit. Then chase the PR.

Like it snug on the arms? Room to breathe under the bar? Start with a shirt you already love.

  1. 1

    Lay your favorite shirt flat.

    Measure straight across, armpit to armpit. That's the chest width.

  2. 2

    Check the length.

    Measure from the back collar seam straight down to the bottom hem.

  3. 3

    Match it to ours.

    Compare with our garment measurements, or let Find my size do the math.

In their words

  • “Fits the big boys.”

    Really comfortable shirt for the big boys. I got the 3XL (I currently weight 305lbs standing at 6'1") and it fits perfectly. A little breathing room so on and so forth and it hangs lower than your normal tee. If you're about my size and want a tighter fit I would recommend the 2XL. Definitely recommend Conquering Barbell and will be back to purchase more.

  • “Exceeded Expectations!”

    Just received my order (3 flags & 2 tee shirts) & was genuinely surprised at how good the quality is. The flags themselves feel high quality, the black background is dark and the material feels substantial. The image on the flags is vivid & sharp with no “bleed over” at the edges of the image. The tee shirts again feel substantial. The images are sharp and vivid with a thickness to them that feels like the print will last. I ordered size L in the oversized tee’s and wasn’t sure how over sized they would be. I was pleasantly surprised that for my build they actually fit comfortably snug in the chest / back / arms & trim in the waist. (For context 5’9, 195)

    All in all, the quality exceeded what I was expecting & I will absolutely be ordering again soon. . Also & important to me, Audie (the owner) was extremely responsive in answering my emails even at evening hours. Great purchase for me.

  • “Fit was fantastic.”

    Very communicative and speedy response when I had a query. The tee came quickly to the uk and the fit was fantastic and very good quality cotton. The print and design is awesome. My husband loves it! As a powerlifter myself I love these niche designs! Thank you so much!
