Nite Ize S-Biner SlideLock Carabiner 5-Pack - Secure Key Holder With Locking Gates

These S-Biner carabiners are seriously handy. Got five in the pack, which is great because you'll want them everywhere. The slide-lock mechanism is what makes them special - each gate locks independently so your keys or gear won't accidentally come off. Made from stainless steel, so they're tough enough for daily abuse. Rated for 10 pounds, which is plenty for keys, water bottles, or small gear. I use one for my keychain, another on my backpack, you get the idea. The locking feature gives you peace of mind when you're moving around. Nite Ize makes clever stuff that actually solves problems - this is definitely one of those products. Whether you're outdoor types or just someone who loses keys a lot, these are worth having around.
