I purchased the Oshawa jacket at JD Sports in a mall in Atlanta so I've no idea about the customer service of Zavetti. My comments simply refer to the folks at JD Sports, and the product itself. Firstly JD Sports is a reputable company and the salespeople in the store were very polite and helpful. 5 stars. Based on the reviews of Zavetti I recommend you find a reputable store that stocks their products and you can deal with a live human being. Check the store's return policy before buying! Now - the Oshawa jacket! I've literally spent hours and hours reviewing all the usual winter jackets (North Face, Fjallraven, Mammut, ArcTeryx, etc etc) and am reluctant to spend $500+ on any item of clothing. I've researched the heck out of fill weight and fill power so I consider myself fairly knowledgeable. I bought my son the North Face McMurdo Down for $275 with member discount at REI, and last year I purchased the Fjallraven Nuuk Parka for myself for $500 direct online. Both of these jackets are extremely warm and well made, but a little pricey. The Nuuk has a fill weight of 250g. The McMurdo has a fill power of 600. These are the 2 factors you need to be aware of when measuring warmth. I can't find either number for the Zavetti Oshawa (yes I've emailed the company but received no reply haha), but I would easily rate it as warm as the other two, possibly even warmer. I wore it the other night when it was a clear sky, light breeze and a windchill of 26F, and with a tshirt and light fleece, I was very warm. It is a very heavy jacket so forget compressing it into a suitcase for travel. It has an extremely durable exterior which shouldn't wear or tear anytime soon. I paid $120 for this and can confidently state it's as warm, durable and WAY more stylish than the others which cost a lot more. It is big (I'm chubby, 5'10", 220lbs) and the XL is a little too big with a t-shirt and fleece underneath. JD Sports currently have it on sale for $85 so I'd grab one while you can.
