    Climashield APEX reaches new heights in combinations of weight and thermal efficiency. Developed from a culmination of over 25 years of manufacturing experience, this innovative insulation is the lightest and most thermally efficient continuous filament insulation on the market today. Like other high-end synthetics, it also maintains warmth in wet and humid conditions.

    Due to it's unique continuous filament construction, Climashield APEX requires little to no quilting. This makes it easier to work with when compared to other synthetic insulations that require quilting panels to avoid shifting/migration. Great for sleeping bags, outer wear, and quilts. 

    For additional information, please visit the Climashield website HERE.

    * Sold by the linear yd, just like fabric . For example, entering a qty of "1" gets you a 36"x60" piece.

    IMPORTANT- Due to size and packaging constraints, our standard max continuous cut for all insulation is 5 yds. If you're ordering more than this and need specific cut lengths for your project, please put a note on your order with cut instructions. We're happy to work with you to make things work :).

Climashield APEX - 10 oz/yard

I bought 2 yards of APEX 10 for a shoulder season (early spring and late fall) quilt. It was a little thick to work with on the sewing machine, but with planning and careful, slow sewing there were no problems. The product lofts to about 6 cm, and without the need for sewn through seams or baffles, I am optimistic that the finished quilt will be plenty warm for colder nights in shoulder season. It doesn't squish as small as high quality down might, but it was much less expensive, won't be as finicky to wash, and no birds were plucked in the making of this insulation.

Thanks for the review David! Those are all the reasons we love using the APEX insulation- more affordable, eco friendly, and easy to work with! We're glad you love it as well. We'd love to see photos of your finished quilt, be sure to tag us on social media!

Why 5 yard maximum?

Bought 20 yards. Don't understand why it had to be cut at 5 yard increments. Website claimed shipping issues, but entire order came in one box anyway. Seems as if I'll need to do some unnecessary splicing since they will only cut on the yard.

Hey Jeff, thanks for the review and we apologize for the inconvenience. Our standard max continuous cut for all insulation is 5 yards but we are happy to work with you in the future to get the correct cuts. Email us at

Best in class

This insulation is fantastic. Was shipped vacuum sealed and well protected. Even the 1.9oz is extremely warm. The 10oz is like a portable oven. Would buy again.

Great customer service and product

All materials were delivered on time and were cut to measurement.

Hi Wayne, I'm thrilled your order went well. Thanks for the review!

This blanket is so incredibly warm that I keep waking up too hot! :-D

The kit is awesome! It's so easy to make if you have basic measuring and sewing skills. The material is fantastic and so supple. I love it!

I probably could have gone with a lighter weight apex so I'll be buying another to make a lighter one too! :)
