Your choice of 10 or 14 lb of grip (approx) on bottle to prevent bottle launches. ANTI-VIBRATION. Locking hardware for safety and security. REPAIR STORAGE OPTIONS. Compatible with AERO POUCH 300 bag or MULTI-STRIKE REPAIR HOLDER. Looking for additional rear storage? XLAB offers two options that are designed to complement DELTA 425 carriers. The AERO POUCH 300 storage bag and the MULTI-STRIKE REPAIR HOLDER. When using these accessories please follow the recommendations below. Due to the extra weight demands that these systems place on the DELTA 425, we only recommend installing one of these storage options at a time. Additionally, installing the AERO POUCH 300 onto the DELTA 425 XT will add an additional 2-3 lb of bottle retention, making it extremely difficult to remove the bottle. We don't recommend using the AERO POUCH 300 with the GORILLA XT Cage.
