Helikon Groundhog Outdoor Tactical Backpack Riding Bicycle Helmet Bag 10L Double Shoulder Soft Pack for Men Camping Hiking

This is the fourth Helikon bag I've bought. This bag is truly a model of lightweight outdoor gear; it's really light. The various straps are all one centimeter wide, which naturally keeps the weight down. When I wear it, it feels snug against my back, maybe even a bit too snug, so I'm a little concerned about breathability. The shoulder straps are quite narrow, and the distance between them feels a bit tight. But since it fits so closely, it should be great for cycling. The bag itself has a capacity of only 10 liters, which can fit a cycling helmet, and if I need to carry other things, I can use the expandable net pocket for the helmet. I'll definitely take it with me on my rides in the future.
