Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Protective Flask Sleeve: Designed to safeguard glass vacuum flasks and spray bottles from scratches, shocks, and temperature changes using durable silicone and eco-friendly materials.
  • Secure Grip System: Combines braided paracord wrist straps with non-slip silicone cup holders, enabling hands-free use and stability for beverages during active or on-the-go scenarios.

Key features

  • 1. Material Technology

    • With braided paracord wrist straps and food-grade silicone, ensure unmatched durability and heat resistance. The paracord material offers 30% stronger tensile strength than standard nylon straps*, while the silicone cup holders withstand temperatures up to 482°F, protecting your drink and device.

  • 2. Interactive Design

    • With an adjustable buckle and quick-release silicone cup holder, securely fasten the holder to your wrist for hands-free use. The ergonomic design allows one-handed attachment/detachment, outperforming rigid plastic alternatives that require tools*.

  • 3. Performance Parameters

    • With adaptable capacity options (12oz–64oz), the sleeves fit vacuum flasks, thermoses, and glass bottles of various sizes. The silicone material reduces heat transfer by 40% compared to bare glass*, keeping drinks hot/cold longer.

  • 4. Scenario Solutions

    • Designed for outdoor adventures and on-the-go lifestyles, the non-slip silicone holders prevent spills during hiking, cycling, or travel. Unlike fixed-size cup holders, these adapt to cups of all shapes, ideal for office commutes or campsite use*.

  • 5. Certification Standards

    • Eco-friendly silicone and BPA-free materials meet FDA food-grade safety standards, making them safer than uncertified plastic alternatives. The paracord straps are also recyclable, reducing environmental impact compared to disposable options*.
