It's all in the details.

Made to be worn underneath our Strata Knickers and Tights but works equally well paired with any of our overshorts.

A “base layer underbib” that offers exceptional comfort with low bulk. The Foundation incorporates the high-performance features of the MK2 including our Clean Finish Construction into a highly air permeable, lower volume package. The body fabric is constructed of an ultra light polyester that breathes and wicks very quickly, making it ideal for a next to skin base layer.

Optional gClip integration connects the Foundation to our Strata Knicker or Tight directly, allowing you to wear an overtight with one set of bib straps instead of two.

Additional features include wide gripper elastic leg band for keeping the bib in place and extremely comfortable soft elastic bib straps. The Foundation is perfect as a chamois solution under all other overtights and overshorts.



Durable Water Repellency (DWR) refers to chemical treatments applied to fabrics to increase their resistance to water absorption. DWR chemical penetrates into the fibers and binds there, protecting the textile so that water beads and rolls off the outer layer rather than being absorbed. This helps keep fabric surfaces dry and clean, which in turn allows fabrics to main their waterproof and breathable characteristics. Significant changes to DWR chemistry are currently being developed, with reputable manufacturers and brands phasing out the use of “C8” based DWR treatments that may have negative environmental impacts. 7mesh works with vendors to ensure we use the best DWR treatments available; our fabrics do not use any C8-based DWRs.
