I prefer military-issue camo which can be purchased online or at surplus stores. I found mine in a military community. The knock-offs don't stop briars and thorns like military-issue does.
I agree with Brittany. GI is the best and it doesn't have to be American. The Swiss camo is excellent and comfortable to wear.
Also remember that camo is only as good as your surroundings will allow. That is why it comes in so many varieties. I have deep woods camo, Fall camo, field camo, and snow camo. I don't hunt the desert anymore or I'd have that also.
I use superflauge. There are 2 questions to ask. Does this pattern break-up my outline and blend in? Does this cammo have UV brightners in it? Don't use regular laundry detergent as it does have UV brightners. Use camo detergent.
