UndrDog FAQ
UndrDog makes men’s hemp clothing from a 51% hemp, 31% bamboo and 18% organic cotton blend it calls DuraFlow™, with no polyester and no PFAS, sold with a lifetime warranty. The answers below cover fabric, fit, washing, shrinkage and the warranty. For questions answered from customer reviews rather than from UndrDog, see the review-based answers.
What is the fabric made of?
What is DuraFlow™?
DuraFlow™ is UndrDog’s patent-pending tri-blend of hemp, bamboo and organic cotton. The three-strand structure holds even tension, which UndrDog says makes it more stable than a two-strand or four-strand construction and is what combines strength, durability and breathability in one fabric.
What is the exact fabric composition?
51% hemp, 31% bamboo and 18% organic cotton. Hemp carries the strength, bamboo the airflow and comfort, and organic cotton the softness. There is no polyester in the blend.
Do UndrDog shirts contain PFAS or polyester?
No. UndrDog states its garments contain zero PFAS, zero polyester and no forever chemicals. That is the reason the founder rebuilt the product after the first hemp-polyester version.
Why does the fabric resist odour?
Bamboo and hemp are both naturally antimicrobial, and the weave wicks moisture away from the skin so it can evaporate. There is no synthetic anti-odour chemical involved.
Is a hemp shirt scratchy?
UndrDog’s blend is designed against that: the bamboo and organic cotton carry the hand-feel while the hemp carries the strength. Reviewers most often describe the fabric as soft, and several note it softens further after the first washes.
How do you wash and care for it?
Does it need special washing?
No. UndrDog says to wash and dry it like any other shirt, with no special care needed. The fabric’s durability and shape retention hold up through repeated machine washing and machine drying on low heat.
Will it shrink?
Some customers report shrinkage, and it is almost always tied to drying on high heat. Washing cold and drying on low or hanging to dry is what reviewers who report no shrinkage describe doing.
Does it wrinkle?
The blend is midweight and holds its shape through the day rather than sagging, which is what keeps wrinkling down.
How does it fit?
What is Alpha Frame™?
Alpha Frame™ is UndrDog’s name for the cut. It hugs close through the arms and chest to make them look fuller, sits slightly looser through the midsection to hide the gut, and uses a curved hem that adds visual height and works tucked or untucked.
Should I size up?
Only if you are between sizes or want a relaxed fit. Most reviewers who discuss fit say the shirt is true to size. It does run tight slightly more often than loose, and the cut is deliberately close through the arms and chest, so buyers who want a looser T-shirt tend to go up one. See the review-based sizing answer for the counts.
Is it comfortable?
UndrDog describes it as a midweight shirt with a higher GSM, designed to be breathable and soft while gripping the body. Comfort is one of the highest-rated topics across the review corpus.
What about the warranty and returns?
Is the lifetime warranty real?
UndrDog states that if the shirt is the wrong size or ever wears out, it will be replaced with a brand-new one free of charge. The customer covers only the cost of sending the original back.
What does the warranty cover?
Both a wrong-size exchange and a garment that wears out. That is what makes a sizing mistake recoverable rather than a lost purchase.
What is the gold bar?
Is the gold bar promotion real?
UndrDog inserts a 1-gram bar of .9999 fine gold into one in every hundred shipments, delivered inside the shirt package. Reviews on this site include customers who received one.
