When it comes to washing your pack, hand washing works best. Simply soak your pack in warm water with a mild detergent. Take a soft-bristle scrubbing brush and gently scrub your pack clean. Hang your pack in a cool area to dry. There are many different gear-specific washes available at most specialty outdoor retailers. If you wish to wash your lumbar pack, you can do this in a Front Loading Washer, warm water, and mild detergent. Please do not use a machine with an agitator.

Once this coating wears off, the metal abrades quickly, and the zipper slider no longer joins the continuous plastic coils securely. The plastic coids then tend to separate behind the zipper slider. One of the keys to zipper longevity is to keep them free of sand and grit. Never step on your zipper, and clean them by washing them with a garden hose with a pressure nozzle. Also, it is important to know the expanding capacity of your pack. Over-loading your pack will put stress on your zippers and could cause failure.\u003c\/p\u003e","published_at":"2021-01-06T08:59:37-07:00","sort_order":"manual","template_suffix":"","disjunctive":false,"rules":[{"column":"tag","relation":"equals","condition":"Shop: Hiking Backpacks"}],"published_scope":"web","image":{"created_at":"2021-01-06T11:26:32-07:00","alt":null,"width":2000,"height":797,"src":"\/\/mountainsmith.com\/cdn\/shop\/collections\/Backpacks-Hiking-collection.jpg?v=1609957593"}},{"id":409451102441,"handle":"sale","title":"Sale","updated_at":"2023-12-10T21:00:19-07:00","body_html":"","published_at":"2022-08-18T10:43:02-06:00","sort_order":"manual","template_suffix":"","disjunctive":false,"rules":[{"column":"variant_compare_at_price","relation":"greater_than","condition":"1"},{"column":"variant_inventory","relation":"greater_than","condition":"1"}],"published_scope":"web"},{"id":234523721880,"handle":"products","title":"SHOP","updated_at":"2023-12-10T22:30:08-07:00","body_html":"\u003cstrong\u003ePlease choose a product type from the menu on the left to narrow down your selection.\u003c\/strong\u003e","published_at":"2021-01-17T11:44:24-07:00","sort_order":"alpha-asc","template_suffix":"","disjunctive":false,"rules":[{"column":"tag","relation":"equals","condition":"Shop"}],"published_scope":"web","image":{"created_at":"2021-01-17T11:41:41-07:00","alt":null,"width":2000,"height":797,"src":"\/\/mountainsmith.com\/cdn\/shop\/collections\/Shop_Category_Image_1-17-2021.jpg?v=1610908902"}},{"id":204574720152,"handle":"all","title":"Shop Mountainsmith","updated_at":"2023-12-10T22:30:08-07:00","body_html":"","published_at":"2020-07-01T13:47:23-06:00","sort_order":"best-selling","template_suffix":"","disjunctive":true,"rules":[{"column":"variant_price","relation":"greater_than","condition":"1"},{"column":"variant_inventory","relation":"greater_than","condition":"1"}],"published_scope":"web"},{"id":401598120169,"handle":"spring-collection","updated_at":"2023-12-10T21:00:19-07:00","published_at":"2022-03-18T15:29:45-06:00","sort_order":"manual","template_suffix":"","published_scope":"web","title":"Spring Collection","body_html":"","image":{"created_at":"2022-03-21T12:45:08-06:00","alt":null,"width":1800,"height":660,"src":"\/\/mountainsmith.com\/cdn\/shop\/collections\/MS_MAR22-SpringGear-CollectionBanner_1800x660_8883f1bd-31df-458c-8270-a114a129d8d6.jpg?v=1647888309"}},{"id":406700425449,"handle":"summer-collection","title":"Summer Collection","updated_at":"2023-12-10T22:30:08-07:00","body_html":"","published_at":"2022-06-23T12:25:07-06:00","sort_order":"best-selling","template_suffix":"","disjunctive":false,"rules":[{"column":"variant_inventory","relation":"greater_than","condition":"0"}],"published_scope":"web","image":{"created_at":"2022-06-30T09:00:29-06:00","alt":null,"width":1800,"height":660,"src":"\/\/mountainsmith.com\/cdn\/shop\/collections\/Mountainsmith_CollectionBanner_GearforSummer_1800x660_a696a826-f30e-49dd-965b-58d82c65a384.jpg?v=1656601230"}},{"id":269036748952,"handle":"summer-essentials","updated_at":"2023-12-10T22:30:08-07:00","published_at":"2021-06-07T16:57:51-06:00","sort_order":"manual","template_suffix":"","published_scope":"web","title":"Summer Essentials","body_html":""}]
Countless hours, thousands of miles, a hundred beers, and one giant beard later and we are proud to introduce the ZERK 40. Co-designed with The Real Hiking Viking, a renowned thru-hiker with thousands of hiking miles under his belt, the ZERK 40 pack stands alone as the ideal combination of weight, durability, comfort, and accessibility.
Co-designed with The Real Hiking Viking, a professional hike-really-long-distances-really-quickly-er, the ZERK 40 was born out of a need for an ultralight pack that can withstand the thousands of miles per year that The Real Hiking Viking already covers. We wanted to make sure that it would allow him to go farther, to hike longer, and to work more efficiently on the trail. Over the course of 2 years of development, the ZERK 40 went through 4 iterations and over 5,000 miles of testing on the Wind River High Rout, the Colorado Trail, The Tetons, and more.
