A slim and trim PALS mountable insulated water bottle holster. We've been using these very happily for a couple of years now. Features include:

• Designed for use with the GI 1qt canteen size. This is the best shape for carrying a quart of water bar none. Nalgene now produces a very nice canteen to the same dimensions.
• Will not fit a standard 1qt nalgene.
• Mounts directly to PALS with an integrated mounting system that is lightweight and offers "sewn on" performance.
• 3oz weight
• Bungy retainer
• Spare slik clip (over the course of two years of use, we've had one slik clip break while trying to clip it in. once clipped in, we've never seen a slik clip break)
• Takes 3 channels and 2 rows
• Perfect for mounting on your waist belt, or the bottom sides of your pack
• Can serve as a "wand pocket" for packs that don't have them
