Priced to United States (`US`) from a cookie, not from this URL.

Follow one of these to price this same page somewhere else. They are
links rather than a pattern to build, because several agent runtimes only
fetch a URL they have already read in a document:

- [Japan](https://supplyvision.app/product/218494-arcteryx-aerios-18-backpack-mongoose-nucleus.md?destination=JP)

Any ISO 3166 alpha-2 code works in `?destination=`, and `?currency=` sets the currency. Both are read from the URL, so no cookie or session is needed. If the country above is not the one you asked for, your fetcher dropped the query string and every total here is for the wrong place.

## Description

From Outsiders Store:

A hiking backpack for a day in the hills. Slightly more stripped back and minimalist in design compared with its competitors, the Aerios 18 still manages to be feature rich with intuitive adjustments. There's 18 litres of storage as well as two large side pockets for bottles or a rolled jacket, freeing up valuable space within. A breathable AeroForm back panel, fitted hip belt and dual sternum straps mean this is a very comfortable pack that feels secure, especially under load. Rounding it out, there’s a bungee system for lashing whatever you need to the outside of the pack. Not available for shipping outside of the UK and EU. (Excluding DE) 18L capacity 210d Hadron LCP lightweight and durable AeroForm back panel for comfort and ventilation Hip belt with stretch mesh and zip pockets Dual adjustable and removable sternum straps Two pole attachments Hydration compatible Front bungee compression system Weight: 567g
