AAndrew M.Super high quality.Just got my first SMBL item. I bought a pair of the Foundation sweatpants and they don’t disappoint. They’re gonna be perfect for rides back home after a day of skiing or fishing out on the SF Bay. Great item.
SStephen WPremium Comfort You Can Feel InstantlyThese sweatpants are unreal. The material feels thick, rich, and built to last while still being incredibly comfortable. They have that perfect tailored look, relaxed without being sloppy, and they maintain their shape wash after wash. Whether I’m lounging, traveling, or running errands, these pants are my first choice every single time. They feel like the kind of premium gear you’re proud to wear.
JJames ScrivenNice pants!Good fabric, not too heavy, not too thin. I washed first time on delicate and hung dry and there was considerable shrinkage. I'm in the XL's and I feel like they used a drawstring from a pair of mediums - almost useless. Still, love the cut and feel.
EEddieI really like these! Great fit and quality.I really like these! The cut and fit are perfect for me. I usually wear a 33/32 pant and got a medium and they're dialed. They're heavy duty and feel thick, but I wore them outside yesterday in 95 degree heat for a bit and felt great.
ZZac M.HVWT SWEATPANTThese sweatpants rock. Super good quality and feel dense.
