Fitbit Air Active Band — Obsidian Large Workout Band

The Google Fitbit Air Active Band is a lightweight, workout-ready replacement band made from recycled-performance materials and designed exclusively for the Fitbit Air in Obsidian (Large).

This performance band pairs durable recycled yarn with a micro-adjustable loop and stainless-steel buckle so the Fitbit Air stays comfortable and secure during daily wear and intense movement. It’s engineered to feel soft against skin and quiet in motion, making the tracker less noticeable while you exercise, commute, or sleep. The Large size fits wrists from 130–210 mm and is tailored for users who need an adjustable, sweat-resistant option.

How does the Active Band stay comfortable during long workouts?

The band uses a blend of recycled polyester, nylon, and elastane yarn that provides stretch without rubbing or chafing. The material breathes better than solid silicone and minimizes noise during movement, so you hardly notice it’s there.

• Recycled polyester, nylon, and elastane yarn for softness and stretch
• Micro-adjustable performance loop for a custom fit
• Low-profile design reduces friction and movement noise

Will this band fit my wrist and stay secure while I exercise?

Yes — the Large Active Band accommodates 130–210 mm wrist circumferences and offers micro-adjustment to dial in a snug fit. A stainless-steel buckle locks the band in place for reliable security during runs, gym sessions, and daily activities.

• Large size fits wrists from 130–210 mm
• Micro-adjustable loop for fine-tuned fit adjustments
• Stainless-steel buckle provides a secure closure

Is this band water- and workout-friendly?

The materials were chosen for durability and ease of cleaning, making the band suitable for sweat-prone activities and light water exposure. While made for active use, rinse and air-dry after heavy sweating or saltwater exposure to maintain appearance and performance.

• Workout-focused construction resists sweat and daily wear
• Easy to wipe or rinse clean after exercise
• Durable yarn blend helps maintain shape over time

What makes this band different from basic silicone straps?

Unlike single-piece silicone bands, the Active Band combines recycled textile yarn with elastane for a softer, quieter feel and better breathability. It offers micro-adjustability for a precise fit and a stainless-steel buckle for stronger, longer-lasting closure.

• Textile yarn blend improves comfort and reduces noise
• Micro-adjustable loop for exact sizing
• Stainless-steel hardware adds durability

Who is this for? The Fitbit Air Active Band (Obsidian, Large) is ideal for Fitbit Air owners who want a more comfortable, low-noise strap built for movement. Choose this band if you need a larger fit range, want adjustable micro-sizing, and prefer recycled-performance materials that balance softness with durability for everyday wear and workouts.
