WILDREEDS Collapsible Soft Flask, Blue, 500 ml, 2-Pack BPA-Free TPU Bottles with High-Flow Bite Valve

These two 500ml soft flasks from WILDREEDS offer a compact, leak-resistant way to carry supplemental water during runs, rides, hikes, or climbs. Constructed from food-grade TPU, the bottles are BPA-free, flexible for packing, and equipped with a wide 20mm cap and a high-flow bite valve so you can hydrate quickly without removing your pack.

How do these soft flasks make drinking easier on the move?

The high-flow valve lets you sip hands-free while keeping a steady stream, and the wide cap simplifies refilling and cleaning. Their soft-wall design compresses as you drink, reducing sloshing and bulk inside a vest or pack.

• 20mm wide cap for quick refills and easy cleaning
• High-flow bite valve for fast sips without stopping
• Compressible TPU body minimizes bounce and weight as you drink
• Leak-resistant construction suitable for dynamic activities

Are these bottles durable and safe for outdoor use?

Yes — made from food-grade thermoplastic polyurethane (TPU), they are designed to resist tears while remaining lightweight. The material is BPA-free and recommended for typical temperatures encountered on trail or road outings.

• Food-grade TPU construction, BPA-free
• Recommended operating range: approximately 0–60°C
• Flexible yet tear-resistant for repeated folding and packing
• Easy-to-clean wide mouth reduces residue build-up

How do I use and maintain the WILDREEDS soft flasks?

Open the wide cap to fill or rinse, then screw it shut and use the bite valve to drink without removing a pack. After use, rinse with warm water; for deeper cleaning, use mild soap and allow to air dry fully while open to prevent odors.

• Fill through the 20mm cap for quick topping-up
• Sip through the high-flow valve without disassembling your kit
• Rinse after each use; use mild detergent for periodic cleaning
• Store with cap open and bottle flattened to dry thoroughly

Will these flasks fit my running vest or hydration pack?

The 500ml size and soft, foldable design make them compatible with most running vests, waist packs, and side pockets of hydration backpacks. Because they compress as they empty, they adapt to tight spaces better than rigid bottles.

• 500ml capacity ideal for short runs, rides, or as backup hydration
• Soft, collapsible shape fits narrow sleeve pockets and vest holsters
• Pair format (2pcs) lets you carry one per side for balanced loading
• Lightweight construction reduces carry weight compared with hard bottles

Who is this for: Runners, trail and ultramarathon athletes, cyclists, day hikers, and climbers who want a lightweight, space-saving backup hydration option will appreciate the WILDREEDS 500ml soft flasks. They’re also a practical choice for anyone who prefers bottles that are easy to refill, fast to drink from, and simple to pack away when empty.
