- What is MIPS and do I need it?
- MIPS is a low-friction liner that lets the helmet slide slightly on impact to reduce rotational forces. It adds protection in angled falls, which are common on trails.
- Is this a road or mountain bike helmet?
- It is a mountain bike helmet built for trail and all-mountain riding. The visor and deeper coverage suit dirt, but it works for commuting too.
- How do I pick the right size?
- Giro sizes the Source in S, M, L and XL. Measure your head circumference and match it to Giro's size chart, then fine-tune with the retention dial.
- Does it work with goggles?
- The visor leaves room for most goggles, but some riders find the fixed visor position awkward. Try your goggles with the helmet if you can.
- How does it compare with the Giro Montaro?
- The Montaro is lighter and has more coverage and a goggle-friendly visor. The Source MIPS costs less and still offers MIPS and good venting.
