I am a medium in a giro helmet – 59cm head
what size flux do you have and what size is your head?

62cm (yes 62cm) and a L/XL

which end of the scale are you on teh adjustment?

to be honest there’s still adjustment left 😯

62cm and a L/XL Flux is a good fit still some adjustment left. 661 Recon is virtually the same helmet.

L/XL Giro Xen/Xar/Feature also very good fit (for me)

L/XL Urge way too small.

7 3/8″ (in us hat size) and from memory a medium flux (I’ll check when i get home) on one of the tighter settings on the clip.

my size is 58.5 cm and my fox flux is a s/m, I,m approx halfway on the adjuster

right s/m sounds fine then – how much adjustment is left?

Just check on the largest setting I can fit three fingers at the back which I did a quick measurement and it looks around 60/60.5

I had a medium Giro Hex, got a S/M Flux- perfect.

Sorry mine is a L/XL and head size is 59cm – clasp at back is on the tightest setting.

58cm and s/m on flux and stryker (which is betterer)

58cm and a S/M Flux. Plenty of adjustment both ways.

I am size 59cm also. I tried both s/m and l/xl. I bought a l/xl after lots of swapping between the 2. Could have got away with the s/m but there wasn’t much/any adjustment left. L/xl is pretty much on its tightest setting but gives room for when my hair is a bit more bouffant or to wear a hat underneath in the winter. I would have felt too restricted and hot in the s/m on hot summer days.
