The Must-Have Backpack Organizer You Didn’t Know You Needed
Backpacks are the ultimate convenience—carrying everything from travel essentials to outdoor gear. But without a backpack organizer, they can quickly become a cluttered mess of tangled cords, misplaced keys, and lost items.
That’s where the FlexPack Plus comes in. This backpack insert organizer is designed to keep your bag structured and your essentials easily accessible. Whether you're packing for a vacation, outdoor adventure, or daily commute, this internal organizer for backpacks ensures everything has its place.
Why You Need the FlexPack Plus Bag Organizer
✔ Backpack Organizer with Handle – Effortlessly store and access essentials like keys, passports, snacks, sunglasses, and more. Sturdy top handles allow for easy portability and hanging when needed.
✔ Insulated Bottle Pocket – Keep drinks cold or warm with an aluminum-lined insulated pocket, perfect for water bottles, thermoses, or energy drinks. Add an ice pack for extra cooling.
✔ Waterproof/Leakproof Large Pocket – Unlike other backpack interior organizers, this one includes a waterproof compartment for wet items, protecting your bag from leaks.
✔ Designed for Any Bag – Works as an internal organizer for bags of all kinds—travel backpacks, gym bags, hiking backpacks, diaper bags, tote bags, and more.
✔ Extra Storage Space – The backpack divider features 6 interior pockets and 4 exterior pouches to keep everything neatly sorted.
Made for Travelers & Outdoor Enthusiasts
The FlexPack Plus is designed for those who pack more—whether for vacations, outdoor activities, or day trips. The expanded center space includes two elastic straps, perfect for securing extra clothes, shoes, wipes, or other bulkier essentials.
However, the FlexPack Plus is NOT designed for carrying laptops. For a work-friendly backpack insert that fits laptops or tablets, check out the FlexPack Urban instead.
Stay Organized, Stay Ready
Whether you're navigating an airport, catching a train, or keeping up with kids, staying organized saves time and reduces stress. The FlexPack Plus makes switching bags effortless, letting you move from a backpack to a travel bag without the hassle of repacking.
Say goodbye to clutter and hello to effortless organization. Upgrade your backpack with the FlexPack Plus today!

Frequently Asked Questions
Everything you need to know about the Stringer Tank Top.
1
How does the Stringer Tank Top fit?
It features a classic, sculpted fit. If you prefer a looser feel for layering, we recommend sizing up one level from your usual top.
2
Will the Tri-Blend fabric shrink in the wash?
Our Tri-Blend is pre-shrunk, but we recommend a cold wash and low tumble dry to maintain the integrity of the hand-made fibers.
3
Is this tank suitable for high-impact training?
Absolutely. The deep Y-back and reinforced seams are specifically engineered to handle high-intensity movement without chafing or restricting your range.
4
Where is this product manufactured?
Every Stringer Tank Top is hand-made in our USA facilities, continuing a heritage of quality that started back in 1990.
