I purchased this on Mercari several years ago, but I never ended up using it, so I'm putting it up for sale. Below is the description from the seller when I purchased it: ------------------------------------------------------------- This is a 30L backpack from Patagonia's "Ascensionist" series, which was a staple for mountaineering. (It is no longer in production) Size: L/XL (the larger of the two sizes) This is a product from the Spring/Summer 2017 collection. I am 171cm tall and of average build, and I used this backpack. People who are around the same height or taller should find this size suitable. ■Features The exterior has a simple design with few parts to reduce the risk of snagging on branches or rocks during mountaineering and climbing. ■Usage I used it for one season, and then I stopped going mountaineering, so it has been sitting unused. There is a feeling of use, fading, and dirt, so please refrain from purchasing if you are particular about these things. ■Other The vibrant orange color, typical of Patagonia, looks great in the mountains. I used it with care, but as you can see in the photos, there are some stains due to the bright color. Please purchase only if you can accept this.
