Zpacks' Bag Ultra 25 With Stick-On Key Zip Pouch The back padding has been used elsewhere, so it shows some wear. As a bonus, I'll include a trifold FP mat. It's in clean condition as it hasn't been used much. This is a lightweight and high-performance frameless daypack made of a strong material. It uses Ultra 100X, so it has excellent strength and water resistance.
