FITLY Sub90 Running Hydration Vest – Lightweight Unisex Backpack with Phone Holder & Thoracic Belt (Black, L-XL)

Experience featherweight comfort on every run

The FITLY Sub90 Running Hydration Vest is built for runners who want freedom of movement without sacrificing essentials. This ultralight vest is designed to feel like nothing on your torso, thanks to four stretch points that flex with your stride. It carries your basics—personal items, keys, and a phone—while keeping your form intact as you pick up speed or extend your route.

Smart design for on-the-go hydration

Sub90 is part of a trio of running packs designed for different distances. For longer efforts, Sub90 offers two accessible stretch front pockets, a dedicated phone pocket, a larger storage pocket, and a thermo-pocket with a 500 ml soft flask for hydration. This setup aims to balance weight and accessibility, so you can stay focused on your pace rather than your gear.

• Two stretch front pockets keep gels, keys, or compact items within easy reach
• A dedicated phone pocket protects your device while you run
• A thermo-pocket hosts a 500 ml soft flask for convenient hydration

The vest is built to stay quiet and secure. A magnetic closure and silent zipper tabs minimize distractions, while water-resistant pockets and an anti-sway pack structure help items stay put as you move. The design prioritizes a snug, secure feel so you can move naturally without constant adjustments.

Material, comfort, and performance

The fabric is odor-resistant, moisture-wicking, and fast-drying, crafted in part from recycled coffee grounds. This setup aims to keep you comfortable through varying weather and pace, without bulk or bounce. The combination of durable construction and a streamlined silhouette supports a steady rhythm on longer runs and fast tempos alike.

• Water-resistant pockets guard belongings in changing conditions
• Four stretch points provide a body-fitting, unrestricted feel

Sizing and fit guidance

FITLY offers XS-S and M-L-XL options to accommodate a range of torso sizes. For the best fit, measure 2 inches below the pectoral muscles; consider seasonal layering when choosing between sizes. The Sub90 is designed to work with a range of body types, prioritizing a secure, comfortable feel during movement.

With the Sub90 you can carry personal items while maintaining your running form. It’s designed to adapt to your routine and support your moments on the move—without promising specific outcomes.
