  • 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 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 :).

Extremely warm for its weight, easy to work with and sew, and durable enough to withstand a few mistakes and seamrips :) Will definitely use synthetic insulation more often!

Hi Franesca, The Climashield is great to work with! Thanks for the review
Apex 2.5

Used to improve insulation in a TNF jacket and made a sleep beanie. Lightweight and warm.


Climashield APEX - 2.5 oz/sq yd


I made some insulated pants with 2.5oz APEX, attached only at waist and ankles. Seems to be holding up. The pants are warm enough to not feel the cold in single digits F on the short walk in to the office. Not sure about sustained cold yet.

Climashield APEX - 2.5 oz/sq yd

Received the insulation on time and as ordered. Plan to double (5 oz/yd) for summer quilt (possibly ≥32F & good if moist) with Ripstop by the Roll 0.66 oz/yd MEMBRANE 10 taffeta nylon material (≈20 oz). Also, plan to use these same materials to sew a weather strip behind the zipper on my Enlightened Equipment Torrid APEX Custom parka.
