I grabbed the 3m ones. Amazon also had them at 2m. I think they used to just be 2.5m but the Slingshot brand has blown up so much they have pink knee sleeves and compression cuffs and tingling jock straps and shit.
I grabbed these because my squat is starting to mimic how Eric Lilliebridge's setup looks... Wide stance and low bar. We'll see - I have so little experience that it's all an experiment.
I do have the Iron Rebel Rhino wrist wraps per @
hawkeye suggestion and they've held up amazing. Very thick, stretchy and it's going on about three years with no sign of breakage... Just some minor thread pulling where the male Velcro grabs a bit around the female patch.
