atelierBluebottle Hiker’s SACOCHE-05 CLEAR(UX-10) I'm not sure exactly when I bought it, but I think it's been less than a year. I've only used it once, when I was having tea, so it's practically new. I couldn't find the detailed specifications online, but I believe it's a translucent white X-PAC material. I remember it sold out quickly, so it might not be a regular product. It doesn't seem to be listed for sale very often, so please take this opportunity! I'm not going to negotiate on the price for now, as it's a hassle. Thank you very much. == Yamatomichi CAYL Ultra Light UL DCF Dyneema Cuben Fiber Attack Sack Mountaineering Trail Running Trail Run Hiking Sub Bag Shoulder Bag
