I purchased size S, it fits perfectly, could say snug, The helmet is a good option, there is some wind noise on the left ear side. Except for thst the helmet is extremely loght weight, easy to wear and reslly comfortable during rides. I personally loved the helmet.
Delivery was fast , people i talked to at Spartan Support were professionals and super helpful.
Highly Recommended :)
Delivered in 2 days even before they shared tracking details. Product was packed good and as mentioned in the order. Perfect
Its a Light weight helmet and wont feel the Neck pain during long travel. Wind noise is minimal compared to other helmets. Built Quality is good.
