Peicees Motorcycle Helmet Bag Folding Lightweight Motorcycle Backpacks for Men Waterproof Large Capacity Cycling Motorcycle Helmet Backpack Riding Storage Bags

works well. the unzip to open up the sizing works larger helmets. Haven't tried my motox helmet in here but a donwhill mountain bike helmet (chinbar + visor) fits well when the extra compartment is unzipped. No word yet on longevity as i just use this to keep gear together when travelling, but everything seems to be decent enough initially.

nice lightweight packable bag. Big enough to hold a full face helmet. Simple enough to use is a lightweight daypack.
