Care for your layer

Hand wash or machine wash on a gentle/wool cycle in cold water (50-68°F). Use a mild wool-safe or pH-neutral detergent. Wash with similar colors. Don't bleach or use fabric softener.

Reshape while damp and lay flat to dry. Don't tumble dry, twist, or wring. Cool iron if needed. Store folded in a cool, dry space with airflow; avoid hanging.

Naturally dyed colors can transfer with sweat or friction. Wear them with dark clothing or equipment, wash sparingly, and avoid citric acid, which can lighten the color.

Love That Alpaca!

If there is a better fabric than alpaca, I don't know what it might be. This fabric simply checks all boxes, light weight, satisfies all temperatures, and looks great. My only suggestion for the alpaca jacket would be to add two pockets, one on each side. My wife is a seamstress so I will ask her to accomplish that plus reduce the large size somewhat. Not enough to be a medium size but just lessen the sleeve length a little. Then it will be perfect!

Love this sweater

I wear this sweater a lot, it's such a good weight and the sleeves are nice and long. Wonderful product.

We're so happy to hear you're loving the sweater! 😊 The perfect weight and long sleeves make all the difference. Thanks for your support, and enjoy wearing it!

One of the best purchases I’ve ever made

I’ve never been so satisfied with something I’ve bought. I hate cold winters and having to wear bulky clothing, this is the warmest and lightest and most comfortable sweater I’ve ever owned. I don’t think the zipper is cheap or bad, it’s just simple. The sweater is so calming and feels like you’re being hugged all day. And it’s fine in warm rooms too. You don’t overheat because it regulates your temperature.

Hi Josh,
Wow! We're truly honored to hear this is the warmest, lightest, and most comfortable sweater you've ever owned. It’s amazing that it keeps you cozy without overheating—just as alpaca wool should! We appreciate your thoughtful feedback and are so happy you’re enjoying it.

Better zipper

I chose XL size to layer under this piece. XL is larger than a regular XL. The zipper is too small and doesn't work seamlessly. For the price of this garment, I would expect a much better zipper

Hi Al, Thank you for your feedback! We're really sorry to hear that the zipper isn't working as smoothly as you'd expect. We appreciate your thoughts on the sizing as well, and we'll take your comments into consideration for future improvements!

Warm sweater

It is a very warm sweater.. However the zipper could be more substantial for a sweater that costs this much.

Hi Jack!
Thanks for the feedback! We're glad you find the sweater warm. We understand your concern about the zipper, and we'll pass it along to our team for review. We appreciate your input and are always looking to improve!
