Whistler range in more detail

The Whistler range is an all-season backpack, which was born on the mountainside, designed and tested by professional photographers including Whistler shooter Paul Morrison, in the extreme conditions of the Coast Mountains of British Columbia, Canada.

These are Lowepro's most versatile packs, which have been designed for extreme conditions, delivering amazing performance for wilderness photographers and adventurers who carry an equal measure of camera, video and functional outdoor gear. The technical Whistler alpine pack is reminiscent of our brand heritage, and the adventures that led founder Greg Lowe to create a carry solution for his passions.

  • Top pocket designed with a high-visibility orange interior; key leash included inside zippered pocket
  • A camera with a mounted long lens can easily be loaded through the top access. Folding dividers configure vertically or horizontally for to fit different types and shapes of gear.
  • Attach heavy gear like skis, ice tools, or professional-sized tripods to the sides and still have access to main compartment.
  • Multiple attachment points make it easy to expand capacity and add trekking poles, snowboard or other alpine essentials.
  • Special Insert pads for controller and drone protect and secure components in the bag.
  • Pack includes a detachable All Weather AW Cover™ to deploy and protect valuable gear from rain, snow, dust, or sand.
  • A dedicated CradleFitTM  Laptop sleeve to fit a 15-inch laptop. Ejector strap makes loading and unloading the laptop quick and easy.
  • Spacious front pocket expands to fit alpine essentials, including a shovel, probe, rope, or extra clothes. A waterproof barrier separates wet gear from main compartment (drain hole at bottom).

Updated Lowepro Whistler Green Line Backpacks

The Whistler green line officially marks the Lowepro commitment to a more sustainable future and shows how they are progressing towards this goal with these environmentally friendly backpacks, as well as bag accessories, organisers and equipment pouches.

  1. Textiles are made with reduced CO2, using recycled polyester from post-consumer recycled bottles, which saves 50% CO2 emissions, while recycled nylon gives industrial waste a second life.
  2. Packaging is now made with 100% FSC-certified hangtags and 100% recycled polybags. Recycled LDPE is used for polybags to reduce carbon emissions and virgin petroleum. All hangtags are made from responsibly sourced paper.
  3. A refined manufacturing process results in -80% less water consumption, using solution dyeing. This involves dyeing fibres before they’re woven into yarn, to reduce consumption of water, energy and chemicals.

The green line score is calculated following the GRI 301-2 standard, measuring the weight of recycled yarn compared to the total yarn. Lowepro measure their solution dye percent by weight using the same method to calculate the green line score.
