The 90 Degree by Reflex Full Zip Runner Jacket, at about $40 (69% less). A slim, fitted running jacket with thumbholes, often named as a Define look-alike. The catch: Fabric and fit are not as refined, and pricing varies a lot by color.
The CRZ YOGA Butterluxe Waist Length Thumbhole Jacket, at about $48 (63% less). Slim, waist-length full zip with thumbholes, zip pockets and the same 81/19 nylon-Lycra blend. The catch: Reviewers say it runs small and can show wear sooner after washing.
It's made of lululemon's Nulu fabric, which the listing describes as very soft, lightweight, sweat-wicking and four-way stretch, with added Lycra fibre. The CRZ YOGA Butterluxe Waist Length Thumbhole Jacket ($48) uses the same 81/19 nylon-Lycra blend.
Yes. The listing mentions zippered pockets, thumbholes and Cuffins that keep sleeves down, a zipper garage against chafing, and a locker loop. All three swaps here also have thumbholes.
BALEAF Laureate Fleece Slim-Fit Jacket ($41) has a warmer fleece lining, but it's cropped. The Define itself is hip length, so the BALEAF works better as a cold-day layer than a year-round one.

Every swap is a product sold in the US that does the main job of the original. Close match is another brand with similar features, Same brand, cheaper is an older, smaller or renewed model from the same maker, and Budget pick is the cheapest thing that still does the job. On each page, Closest match is the close match nearest the original in price, and Lowest price is the cheapest swap. We compare published specs, retailer listings and reviews; we don't test products ourselves.
A cheaper product is cheaper for a reason. Each swap says what you give up, like weaker noise cancelling, a smaller screen or a shorter warranty, so you can decide if the savings are worth it.
Prices are typical US prices from retailer listings and price trackers, last checked October 2026. They are not live Amazon prices, which change often. When a price couldn't be confirmed, the page says “Check price on Amazon” instead of showing a number.
