The Katalyst Base Layer works really well-comfortable, warm, and great for workouts. The sleeves are a bit shorter than I’d prefer, but overall it’s a solid, high-quality set.

Great product when it remains intact. Efficient and effective workouts. Verified on a personal pre/post bioelectrical impedance and functional fitness testing. However, customer service took a significant dip in recent months. I wonder if Seema (earlier review) and I are the only ones not receiving responses from the company. I purchased a gen 3 in November. Typical use (3x/week) and care per instructions. Pads started to peel off on both the chest and legs after a couple of months. Sent a video/complaint via email and got a replacement sent immediately. Same thing about two months after that. This time though no response from customer service until I threatened a report to FDA marketwatch (peeling pads were associated with more stinging during use--safety??) and BBB. Received a next day response with a promise to send a third gen 3 suit replacement and then never heard back despite multiple follow ups. Have since filed a BBB complaint and just received word from them that Katalyst has not responded to their outreach. If it were not for the pads peeling off on each of the received suits, I would be a satisfied customer and enthusiastic proponent. However, looking at the absence of either gen 3 or gen 4 suits for sale on their site, I wonder if the company is in financial/supply chain trouble.
