Product Description

The waterproof Whiteout 45 is made of a unique bluesign© certified UHMPE ripstop fabric. The extremely abrasion and tear resistant as well as UV resistant material makes it the ideal companion for mountaineering and expedition use. It also offers enough speace for multi-day tours.

This backpack combines minimalist features and waterproof construction with a roll-top closure and remarkably lightweight, material. The seams are seam-taped and the fabric laminated with TPU film withstands a water column of 20'000 mm.

The low profile ice tool configuration ensures a snug attachment of alpine tools. An outer pocket with zipper provides space for smaller items and minimal daisy yet versatile chains attachment various options for gear attachment.

The carrying system is intentionally minimalist in a lightweight construction, and a removable, padded hip belt provides better support. A removable back panel with EVA padding can be used as a sit pad in a bivy if needed.

The EXPED backpack line includes both waterproof and weatherproof models. Waterproof means these backpacks keep water out unless submerged in water. Weatherproof means that the fabric and seams are completely waterproof, but zippers and hydration ports are water resistant and not 100% waterproof.

All other backpacks in the EXPED line have coated fabrics to prevent water penetration. These backpacks do not have taped seams. Typically, other features such as durability or weight reduction are the focus of these products and are designed to be used with our waterproof drybags to keep the contents dry.

All backpack fabrics used by EXPED are by definition "waterproof" due to their coating and have a water column of at least 1500 mm. The distinction therefore relates primarily to construction and processing:

In "water-resistant" backpacks, water can enter the backpack through the seams and through the zippers.

We define "weatherproof" as backpacks with a water column of at least 3000 mm, which also have water-repellent zippers to the main compartment and seam-taped seams. Although the zippers are very water repellent, water can enter through the zipper during heavy rains.

Our backpacks labeled "waterproof" have a water column of 3000 to 10'000 mm, are also seam sealed or welded, but use water repellent zippers only on exterior compartments, not on the main compartment. The main compartment of these models have a waterproof seal by means of a roll top. In these models, we do not refer to exterior compartments with zippers as "waterproof", but only as "weatherproof". No rule without exception: A 100% waterproof Drysuit zipper is used on the Tempest Duffles.

EXPED measures the volume of its packs using standardized plastic balls. The volume declarations are exact. The external dimensions are measured at the widest point. Calculating volume based on dimensions can lead to different values.
