I picked up an Adidas Premiertek Titanium last year. Love the helmet, light, good vision etc but my head overheats after about 10 mins, even just netting. I've picked up a halo headband as recommended here but that's just more to divert the sweat (nice).

Once I'm outside in the heat of the English summer (), I imagine it can only get worse. I've been looking at the Masuri Vision series as an alternative and just wondering if anyone has moved between the two helmets and can comment on airflow/head heat?

I had an Ayrtek with ASIC liner, while ventilation wasn't too bad, I did find Vision series slightly better with regards to keeping cool. However my vision was worse in Masuri compared to Ayrtek.

If ventilation is a concern, have you looked at Albion.

Never really looked at Albion - are they known to be cool?

They have more ventilation holes and are (apparently) lighter.
I've just got an albion so will put one of each on the scales tonight

The majority of cloth covered helmets only have small ventilation features that are circular in shape with a hole diameter of 10mm or so and typically use a foam liner underneath a fibreglass shell.

 the plastic models on the market are more susceptible to more ventilation but will use an EPS liner in them to ensure they pass the impact absorption drop test.

All of these things are present to absorb impact but as a byproduct arent particularly good at allowing heat to be emitted through them. During nets its not like being outdoors where there is usually some wind to pass over the helmets and into the vents features on them.

The helmet with the most ventilation is prob the GM Purist Pro model.

So reading between the lines, they're all much of a muchness? ie, we'd need a cloth covered helmet with bigger holes or a lesser insulating EPS liner?

Yes its about obtaining the balance really between design and performance.

The cloth covered shells usually use fibreglass shells with offer the structural strength and good impact absorption properties but insulate the head causes sweating. Where as the plastic shelled models offer a thinner shell but need to use an EPS liner for impact absorption which then insulates the head and causes sweating.

During testing the BSI pick the area of perceived weakness to perform the drop test, which inevitably in any ventialtion feautre as its a hole in the shell. Make the ventilation too big and it will lead to a failure when being tested, make it too small and the wearer gets less air flow but the helmet passes the test.
