Boy I hear ya all!
REI is the only cycling shop near me (Paradise Valley AZ). They only sell XL (& you are lucky to find that).
I guess if you are fatter than they like, you are out of luck.
REI is a very prejudiced company.
Same problems with their sleeping bags.
I have had major health problems (50# weight gain, unable to walk), from birth defects that caused early onset arthritis in my joints that manifested at age 44, so have been in a wheel chair for 5 years. I finally got 1 joint replaced April 2007 (Against Drs orders because I am too young).
I have found REI XL, fits like a mens medium (like in my olden days). If you are size 38 waist, you need an REI XXL (but you will never find it there).
By the way, I am finally riding again. I used to do 1/2 centuries 20 yrs ago (Apple Cider Century in Michigan, anyone know that one??)
I am only riding 5.5 miles at 9 MPH , just started this week. Hallelujah!!!
Maybe I could do the 25 milers again, at least I hope!
