Best leash for trail running, hikes, or just gallivanting about areas where dogs are not limited to sidewalk widths. To me, these inspire confidence and control in impulsive pups (my opinion) who are still learning the rules. The allow escape routes for walking two pups if one happens to be over reactive when they see stranger dogs. It has the grab handle near the collar/harness so to allow fast intervention when needed. Compared the 12 yo Roamer to this new tri-color version and could not be more thrilled with the updates. You can see the bungee is woven much tighter, and while it's taken me time to get used to the extra spring this creates, my dog cannot "roam" too far from me due to this, and he is learning the limits more quickly than he has walking for weeks on the older, more relaxed/albeit also stretched out version.My star deduction is due to the clasp. Wish the clasp was a carabiner instead of this tiny little swivel clip. It seems easy to undo and in trying to connect the leash to BOTH the Ruffwaer Flagline Harness (check my review of that as well as to the Ruffwear Chain Reaction Martingale collar, it is a tight fit and I worry that when pulling hard, the overlapping metal could be easily opened. It is just not as secure as a carabiner. Would love if Ruffwear could customize mine with a swivel carabiner instead - which they may need to invent first.As a decades long Ruffwear believer, this company knows what type of gear is needed to keep dogs safe while adventuring with them. None of my items have ever failed and they seem to keep the best aspects and only update what will make the products better. Performance over profit. ? Perhaps. But pups over price any day. And that's what they bank on.
