Spigen Athlex Air Apple Watch Band Review: Lightweight Fabric Tested on Ultra and Series

Is a $20 fabric band for Apple Watch actually worth strapping on over silicone? I had the same question before testing the Spigen Athlex Air Apple Watch band on both my Apple Watch Ultra and Series 1.

Spigen built the Athlex Air as a lightweight, breathable nylon sport band with a hook and loop fastener designed for one-handed adjustment. It fits every Apple Watch from 42mm to 49mm, covers Series 1 through 11 and both Ultra models, and it ships in four colorways with yellow accent stitching.

I wore this band through gym sessions, outdoor runs, and regular office days to see how the fabric and Velcro held up across different conditions. You can watch the full test on our YouTube channel, but here is the written breakdown. The short answer: the comfort surprised me, but there is one thing worth knowing before you order.

What I Liked About the Spigen Athlex Air Apple Watch Band

The Athlex Air impressed me across five areas that matter for a daily sport band. Here is what stood out.

Secure Hook and Loop Fastener

The hook and loop fastener on the Athlex Air locks into place before the Velcro even makes contact. During my testing on both the Apple Watch Ultra and Series 1, the band showed zero slip through runs, lifts, and all-day wear.

That initial hook catch gives extra security that cheaper Velcro bands skip. It means the band stays put even if the Velcro tab loosens slightly during heavy movement.

Breathable Fabric for All-Day Comfort

The nylon fabric on the Athlex Air sits soft against the wrist without the sticky feeling silicone bands create during sweat. 9to5Toys rated the comfort at 9 to 9.5 out of 10, calling it more comfortable than the Apple Alpine Loop after extended wear.

I found the breathable textile material handled sweat and water noticeably better than my previous silicone sport band. Air flows through the weave, which kept my wrist dry during hour-long gym sessions.

Works With Every Apple Watch Ultra and Standard Model

Compatibility covers every Apple Watch from 42mm to 49mm. That includes Apple Watch Ultra 3, 2, and 1, Series 1 through 11, and all SE models. I tested installation on the Ultra and Series 1 and both clicked in under a minute with no fitting issues.

The wrist size range runs from 155mm to 230mm, which accommodates most adults. Spigen designed this as a one-size-fits-most band, and the adjustable loop handles the range well.

One-Handed Fit Adjustment

The pull tab lets you tighten or loosen the strap with one hand. Spigen calls this start and stop sliding technology, and it works as advertised. You grab the tab, pull to your preferred tightness, and press the Velcro down.

9to5Toys confirmed this one-handed adjustment claim in their hands-on review. For runners who need a quick tighten mid-stride, this feature alone justifies choosing the Athlex Air over bands that require two hands.

Sporty Design With Premium Stitching

Yellow stitching runs along the band body, adding a sporty accent that elevates this Apple Watch accessory above generic nylon straps. The four colorway options include Active Green, Active Navy, Active Black, and Active Gray.

At $19.99 (as of March 2025), the Athlex Air costs roughly 80% less than the Apple Trail Loop while delivering a comparable fabric band experience. That value stands out in a market where Apple charges $49 or more for similar loop-style bands.

What Needs Improvement

No product is perfect at any price, and the Athlex Air has a few areas worth flagging.

Velcro Longevity Remains a Question

The single Velcro strip holds securely right now, but long-term durability is the open question. Dust, sand, and prolonged moisture exposure can weaken hook and loop material over time. Apple’s Sport Loop uses multiple Velcro contact sections for redundancy, while the Athlex Air relies on just one strip.

Some users on forums have reported that fabric band Velcro typically maintains grip for one to two years with regular use. At $19.99, replacing the band annually is still cheaper than a single Apple Sport Loop, but it is worth noting.

Sizing for Slim Wrists Could Be Tighter

The 155mm to 230mm wrist range covers most adults, but reviewers with slimmer wrists noted limited room left for the Velcro tab once tightened. If your wrist falls near the 155mm minimum, the fit may feel slightly loose compared to a sized silicone band.

There is also a small bump where the Velcro tab folds over. It is minor and not uncomfortable, but you can feel it if you press against a flat surface.

Single Velcro Strip vs Multiple Sections

The Apple Sport Loop and some competitors use multiple hook-and-loop sections spread across the closure. The Athlex Air has one continuous strip. During my testing this held without issues, but users who push their bands through rugged outdoor activities may prefer the redundancy of multiple sections.

How the Spigen Athlex Air Compares

Two competitors stand out as the most relevant alternatives to this Apple Watch band.

Spigen Athlex Air vs Apple Sport Loop

The Apple Sport Loop costs $49 and uses the same hook and loop adjustment style. Both bands deliver breathable fabric comfort and one-handed tightening. The Athlex Air matches the Sport Loop in daily comfort at less than half the price.

Where the Sport Loop edges ahead is in Velcro coverage and long-term build quality. Apple spreads its hook and loop material across a wider contact area. If your budget allows the premium and you want maximum closure durability, the Sport Loop is the safer long-term pick.

For most users who want comparable comfort without spending $49, the Athlex Air at $19.99 (as of March 2025) delivers the better value.

Spigen Athlex Air vs Spigen Lite Fit

The Lite Fit is another fabric Apple Watch band from Spigen, priced similarly. 9to5Toys rated the Lite Fit at 7.5 to 8 out of 10 for comfort, while the Athlex Air scored 9 to 9.5. That jump in comfort makes the Athlex Air the clear upgrade within the Spigen lineup.

The Lite Fit uses a different nylon weave and buckle-style closure, which some users prefer for its traditional feel. If you want the softest fabric band Spigen offers, the Athlex Air is the one to get.

Final Verdict

The Spigen Athlex Air delivers standout comfort and practical design in a $20 Apple Watch band. The breathable nylon fabric, secure hook and loop fastener, and genuine one-handed adjustment make it a strong pick for workouts and daily wear.

I’m giving the Spigen Athlex Air a 4.2 out of 5. The only real concerns are Velcro longevity over extended use and slightly loose sizing for very slim wrists. Neither issue is a dealbreaker at this price.

Bottom line: if you want a comfortable, breathable fabric band for your Apple Watch without paying Apple prices, the Athlex Air is the one to get.
