I'll have to get pictures later, but I like leather, but Kydex is a great outdoors holster material. The biggest issue is if you're packing a pack with a waist belt...than you have to get creative. I'm really thinking about a Safepacker for the waistbelt and keep the kydex for when we hike around after we set up the base camp. IWB is a little too uncomfortable for hiking and scrambling, so I usually switch to a strong side (right for me) OWB holster. I've used a shoulder rig for my Ruger .44 when hunting, but it's not something I've considered for backpacking.
