Inspired by thru-hikers across North America, the women's REI Co-op Flash Air 50 pack is our lightest backpacking pack yet—perfect for those who like to stretch the miles without sacrificing comfort.
- Ultra-high-molecular-weight polyethylene (UHMWPE) fabric is amazingly durable and allows for a surprisingly long lifespan for such a lightweight pack
- Nonfluorinated durable water repellent (DWR) helps moisture bead up on the surface
- 3D contoured hipbelt and ventilated back panel are comfortable all day for loads up to 25 lbs.
- Roll-top lid provides weather resistance and allows compression and adjustment of internal volume
- For a tight load and good balance, Packmod compression straps (included) can be run from any loop to any other loop, so you can sculpt your pack to the shape of your load
- Packmod mesh pocket on the shoulder strap is great for phone, snacks, sunglasses and more—or you can take it off altogether to reduce weight
- Compatible with Packmod hipbelt lengthener and Rainshield pocket (accessories not included)
- Water bottle pockets are positioned forward on the hipbelt so you don't have to remove the pack to grab your drink; cinch closures keep a good grip on slim water bottles
- Exterior side pockets and hipbelt pockets are great for storing light items that you want to keep handy
- Large front pocket is great for rain shell or other gear you may need to access quickly
- Top Y-strap helps you store excess items, including some bear canisters, on exterior of pack
- Attachment loops and removable tool keeper allow trekking poles, ice axes and more to be lashed on, expanding your carrying ability while keeping the load stable
- Daisy chain with multiple attachment points allows for tailoring exterior loads
- Internal hanging loop secures a hydration reservoir (not included); pack design allows tube to be routed over either shoulder
- Also comes with a handy mesh pouch (6.3 x 8.7 in.) to store or organize removed Packmod accessory straps or other small items
- REI is Climate Neutral Certified; as we work to actively reduce our footprint, we measure annual carbon emissions and purchase an equivalent amount of verified carbon credits
- Contains materials that meet the bluesign® criteria
