About the Stir 25
The Thule Stir Alpine Mountaineering Backpack is designed to support any adventure with a highly weather and abrasion-resistant coated nylon fabric. The fast-access side zipper allows you to find contents toward the middle and bottom of the pack, providing quick and easy access to the contents within.
Offering an extremely generous 25L capacity, the Stir Alpine also features a storm flap for extra weather protection when the lid is removed. It’s extremely easy to access protection with the integrated gear loops making it a very versatile adventure backpack.
You can securely attach an ice axe or trekking pole with dedicated loop attachments and smaller items can be easily stored in the interior mesh pockets. The removable lid, frame sheet, hip belt padding and sternum strap allow pack weight to be reduced for light and fast missions.
The Stir Alpine is also hydration compatible and features a reservoir sleeve with a drink tube exit port (reservoir sold separately). Attach a climbing rope or jacket with the underlid compression strap.
