Comet™ Bite Valve Sheath 2-Pack

The fit on my Comet bite valve is snug and secure, no leaking at all. I've been using the same pack for a few weeks now and the soft silicone still feels new.

The soft silicone on these sheaths is noticeably more flexible than the stock ones, so biting down to drink takes way less effort. They slipped right onto my existing valves with no fuss, and the two-pack means I’ve got a backup ready for when the first one wears out.

These sheaths gave my old bite valves a much softer feel on my teeth during long rides. Silicone seems durable so far, and having a spare in the pack means I'm not stuck if one tears.
