30 and 45 metre lengths with a tight-eye spliced at one end. Donaghys Cougar Blue has heritage. First launched in 2012, Cougar Blue was developed in collaboration with Donaghys and Grant Cody and Scott Forrest to meet the demands of competition tree climbers. The benefits of this tighter weave, 11.7mm climbing line soon proved beneficial in the work environment as well. The abrasion resistant HT polyester cover offers superior grip and friction hitch compatibility. Mixed climbing (SRT and DbRT) was almost unheard of back in 2012, but now many aerial arborists employ both climbing systems. As a result, Cougar Blue has found a whole new legion of followers.
