Seneca
”I love the clothes because they create a smart, confident look without limiting my movement.”
Jon, Washington DC
”In a word, I'd describe Seneca as versatile. The material is soft and stretchy like sweats, but the clothes look and fit like tailored clothing. My new go to.”
Ravi, New York
”True comfort is the combination of physical and mental. Seneca gives me the confidence of looking good to match the comfort I feel.”
Jordan, Los Angeles
”Comfortable and versatile - pairs with any buttondown and also looks great fully zipped up.”
Alex, New York City
”After 18 months, I couldn't imagine wearing real work pants anymore. With Seneca, I can come back to the office comfortably.”
Sacha, New York City
”I appreciate the thoughtful details of the clothing. Well made and versatile”
Alex, San Francisco

Pursuing the vision
of who you want to be
not only gives life meaning,
it moves us all forward.

This is Seneca.

Philosophy

Measurements. All garments are hand-measured for accuracy.


It may be helpful to compare these product measurements to a similar garment you already own. To do this, place the garment on a flat surface and take all measurements from the outside.
