    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. 

    Chimashield APEX also delivers superior warmth at lighter weights with its unique, continuous filament properties, reducing the overall weight of a sleeping bag, jacket or pair of pants. Climashield APEX insulation is highly compressible and maintains thermal efficiency even after multiple uses, being stretched, packed or washed.

    For additional information, please read more below or 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!

Simply the best

best insulation for most warmer temp quilts, paired with hyper d 1.0 it makes the perfect ultralight quilt, have both 40 degree and 30 degree versions and both are fantastic. Easy to sew of course, and design is simple.

Thanks for leaving a review Chris! We hope your quilts keep you warm all winter. Try a quilt with 0.66 MEMBRANE 10 as well. Perfect for Ultralight camping!

Super easy to work with.

I’ve made two quilts one with the 5 oz and one with the 7 oz variants. I was nervous to try this at first but the apex insulation is super easy to use and wonderfully light and warm!

Starting a new DIY project is always nerve-wracking, we are glad you had a good experience! Thanks for leaving a review Bowen. We hope your quilts keep you warm!

DIY Apex underquilt 3/4 length

I just spent my first night hammock camping with my new DIY underquilt. I was toasty warm on a windy 44 degree night. I found the 3/4 length plenty long enough for my 5’6” body with no cold spots. I followed all the instructions and am happy to say the quilt was easy to adjust to my hammock set up. Am very pleased with the results of my finished project. I have enough materials left to make some Apex booties, mitts and/or a hood for colder nights.

Thanks for your review and feedback, Deb! We're glad the hear that the 3/4 length was a perfect fit and that it kept you warm throughout the night. We'd love to see photos of your hammock set up, be sure to tag us on social media!
