The Lowepro Whistler BP 350 AW II and the Shimoda Action X70 are both camera backpacks aimed at outdoor shooters, but they take different approaches. The Whistler is a traditional trail-oriented camera pack, while the Action X70 is a roll-top pack built around a removable camera insert. Choose by how much gear you carry and how you like to reach it. Confirm exact sizes and capacity on each maker’s page.

What Each Pack Is For
The Lowepro Whistler line is designed for photographers who hike to a location and want protected camera storage in a pack made for the outdoors. The BP 350 AW II sits in the mid-size range of that family and is aimed at carrying a camera body, several lenses and some personal items.
The Shimoda Action X series targets adventure and travel shooters. The X70 is typically described as a larger roll-top style pack where the camera gear sits in a separate core unit that can be removed, leaving the main pack usable for other loads.
Key Differences

|---|---|---|

Questions to Ask Yourself
- How many bodies and lenses do you carry on a typical trip?
- Do you want the camera insert to double as a separate bag?
- Will you pack clothing, food and a jacket in the same pack?
- Do you prefer quick side access or a top-opening layout?
How to Decide in Four Steps
- List every item you carry, including tripod, water and layers.
- Check that your longest lens fits the interior space shown by each maker.
- Think about airline carry-on rules for your usual trips, and check the current rules of your airline.
- Try each pack loaded, if a local shop allows, to see how the harness feels over a long walk.
Comfort and Weather Considerations
Fit matters more than any feature list. Torso length, hip belt shape and strap padding change how a pack feels after hours of walking. Weather resistance also varies between designs, so read what each maker says about covers and fabric, and treat any claim as the maker’s own rather than a guarantee.
FAQ
Which one holds more?
The Action X70 is generally the larger and more flexible of the two, but check the maker’s published capacity for both.
Can either pack carry a laptop?
Many camera packs include a laptop sleeve, but sizes differ. Check the maximum laptop dimensions listed for each model before you buy.
The Short Version
Choose the Whistler BP 350 AW II for a straightforward trail camera pack. Choose the Action X70 when you want a modular system for longer trips with more non-camera gear. Verify all specs on the makers’ pages.
