Shop the Flex KitWhen Rental Makes Sense
Four moments the rental earns its keep.
Road-trip or event block.
A tournament week. A race taper. A film shoot in Austin. Ship to the hotel or the Airbnb. Return when you're done.
Pre-purchase trial.
You're evaluating the $2,799 kit. A week at home with the real thing is the cleanest way to decide. Rental credits toward purchase.
Acute injury window.
A defined 4–6 week recovery arc — post-surgical, post-concussion, post-flare. Rent for the window, return when the window closes.
Seasonal training block.
The month of two-a-days. The pre-camp build. Six weeks of daily use, then a break. Rent the suit like you'd rent a house.
What Ships
What's in the box on arrival.
The Flex suit
Professionally cleaned and packaged. Extra-large diagonal zipper, arm-access cuffs. Ships in your size.
Filling kit + hydrogel
Regulator, filling gun, USB-C vacuum, seals, and a 250mL bottle of hydrogel — enough for the full rental period.
Instructions + return label
Quick-start card plus access to the 6-minute video. Prepaid return label inside. Pack it back the way it arrived.
You source the CO₂ tank locally (CGA-320 — welding supply or beverage distributor). We include the supplier locator.
Watch Before the Box Arrives
Ross walks you through the whole session.
Hydrogel. Zip. Vacuum. Fill. Sit. By the second session, most people have the setup down to five minutes. The video is on the quick-start card — and here, in case you want to watch the week before your rental ships.

The 60-Day Rule
Every rental, every session, credits toward the kit.
Rent the Flex Kit for a week, a month, or a trip. Book a single session or a 4-pack. Inside sixty days of your first rental day or session date, apply the full amount you've paid against the purchase price of an AEIR Flex Kit, Flex Pro, or Full-Body Side-Zip.
No coupons. No haggling. The credit is automatic at checkout with the original purchase email.

A Renter's Story
"I rented for the Ironman taper. The kit was in the driveway two weeks later."
"I wasn't sure about a $2,799 purchase without using it for real. The rental arrived on a Monday. By the weekend I'd run through six sessions in my living room and understood exactly what it was doing. The rental fee credited back against the kit. Zero regret, better decision."
Logistics
How the rental actually works.
Shipping
Ships within 2 business days of order. 3–5 business day ground to the continental U.S. Rental clock starts on your confirmed use date, not the ship date.
CO₂ tank
Not included in the rental. Sourced locally. Standard CGA-320 — welding supply, homebrew, beverage-gas supplier. Typical cost: $20–$40 for a small tank. Rental duration of 1 week usually uses one tank.
Return
Prepaid UPS return label in the box. Drop off at any UPS counter by your return date. Suit is professionally cleaned between rentals.
Damage / insurance
Normal use is covered. Damage beyond normal use (tears, lost filling kit components) is billed at cost. Optional rental insurance ($29) waives damage liability up to the full kit value.
Cancel / extend
Cancel 48 hours before ship date for a full refund. Mid-rental extensions available at the weekly rate; call or email by day 5 of a 7-day rental.
