  • 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 ydjust 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 :).

DIY Apex underquilt

Good product. Figured out how to sew crooked wavy seams, but still held up well. Really warm. Day after I made it, camped in low 30 degree weather and was warm and toasty the entire time.


Excellent material. I ordered calendered for outer shell of a sleeping bag and uncalendered for the inside. Worked out perfect: tighter weave for wind resistance and a softer feel inside.

Climashield APEX - 5oz/sq yard

Late review of this purchase because I had to design & sew an under quilt & have finally had a couple of cooler nights to test it. Really happy with the quality of the climashield, very easy to sew & packs down to a very compact size considering it’s a full length under quilt. Delivery was quick (to Australia) & happy to purchase through RSBTR in the future.

Love my new underquilt!

The 3/4 under quilt kit was easy to make and fun! Just tried it out camping with my hammock and it is very warm. The online directions said to trim the width of materials. DON'T trim it down! Trimming the width down can make is so the underquilt doesn't encase you fully while in hammock. My suggestion is to trim width for warmer weather climates and keep width if you are going to be in cooler weather.
The underquilt doesnt pack down super small but fits into a stuff sac that's a little less than 1 sq ft.

My favorite part of ordering from Ripstop is the variety of colors. Gotta love the Hot Pink and Robins Egg!

Awesome insulation

I’ve always been a down guy. I recently made myself an Apex 3.6 quilt and really love it. This is so easy to work with. My wife wanted something a bit warmer, so I made one from 5.0. It’s insanely warm for the weight. Love it. Great service, as always.
