REI Co-op Flash

The pack is designed to carry loads up to 30 pounds. It performs best when packed light, making it an ideal choice for ultralight or lightweight backpacking setups.

Yes, the Flash 55 features an adjustable torso system. You can easily slide the harness up or down to dial in the fit to your specific back length.

The Packmod system allows you to strip down the backpack by removing modular components like the lid and hip belt. This helps you shed extra weight when you don't need the full capacity or organizational features.

While the roll-top closure is highly effective at keeping gear secure and protecting against light rain, it is not fully waterproof. We recommend using a pack liner or dry bags for your critical gear in wet conditions.

The shoulder straps include convenient, accessible pockets designed to hold small essentials like snacks, a phone, or a soft flask, keeping them within reach while you are on the move.

The Flash 55 is a popular choice for thru-hikers due to its lightweight construction and customizable features. However, because it is optimized for loads under 30 pounds, it is best suited for hikers who have refined their gear list to keep their base weight low.
