Alpaca Rittervest™
The quality of the vest is excellent. The vest looks exactly like the images on the website.
Exellent quality and fit.
The initial vest had a stuck zipper, and Gabriel was extraordinarily accommodating in arranging an exchange. I have not yet worn it because it’s finally warm here in Kentucky, but am sure it will be perfect
This has been a horrible experience! It started by getting over charged there fees and taxes are insane and don’t even add up properly.
Delay in shipping is also a major concern. Was told my items would ship today after I requested an update on the order. The shipment did not happen as promised.
