I might as well jump in here.
Smitty's: Poly/Spandex
94X V1: 300x300 100% Polyester
Our original (Classic) cut on the 94X V1 is what you'd expect from being designed over a decade ago. Wide.
We've revamped our whole pant line up for 2024, some of which isn't released yet.
94X V2: A refresh, offered in 3 different fits. Classic, Straight and Tapered (Base, flat front only on tapered)
Core Lightweight: 150x150 Polyester. Available in straight fit, flat front only.
BFX Pro: Replaces the MLB Pro which is more similar to the Smitty pant in terms of fabric. This will be a 100% polyester pant but it uses a proprietary yarn to mimic Spandex while dying better and fading slower in the sun. It's MSRP is will be well above the Smitty pant though. Will be available in straight fit. Pleated or flat front.
