This is an Ozone Paragliding Parazak. There's no size label, so I can't say for sure, but it's several sizes larger than the 110L and 130L packs I own. Also, I could easily fit a ML size Delta 3 + L size X-ALPS GTO pod harness + helmet and winter jacket with plenty of room to spare, so I think it's probably a 175L size. For size reference, I've placed a scale (measuring tape) next to the product, so please judge for yourself. #Paragliding #LargeCapacityBag #Rucksack #Backpack 【Notes】 ・Scale is not included. ・This is a used item, so no claims or returns are accepted. ・Shipping will be in simple packaging using recycled materials, so please be aware of this. ・Instant purchase is OK.
