I'm not entirely sure what your looking for but there are tons of shops in SLC.
- Sports Den / Christy Sports are kinda expensive but have lots of gear
- Milo and Salty Peaks. These are snowboard shops but still got outerwear
-I believe there is a 4FRNT store somewhere I have never seen it
I'm sure there are tons more but those are the only ones I use and have heard of.
