My POE Thermo sleeping pad's insulation began separating from the pad's inside top surface, resulting in obvious cold spots. I emailed Hyalite to see if they would support a warranty claim. Here is the response from Matt Irwin of Hyalite Equipment (some words are identical to words already posted in this thread):
"Pacific Outdoor Equipment and Hyalite Equipment are not related entities – not renamed. Long story short, the employees were buying Pacific Outdoor from the founder and the founder stopped responding, leaving no choice but for the staff to resign. The ex-staff started a new business called Hyalite Equipment. As far as I know, Pacific Outdoor Equipment, Inc still exists the contact information I was given by the Pacific Outdoor Owner is 310-344-1222 and PO Box 13896, Torrance, CA 90503. Unfortunately, I cannot warranty this product since it was sold under Pacific Outdoor Equipment you need to try and contact them. If you are interested I can offer you one of our pads for a discounted price."
I haven't tried calling the provided phone number yet. Fortunately, I purchased the pads from Backcountry.com, who has a similar unlimited return policy as REI.
