I've got the insulated and uninsulated coveralls, with headcover, gloves, etc. I really like the pattern for later in the season when most of the leaves have dropped or in the winter. I put the S&L pattern in the same category as Predator Fall Gray or Brown and ASAT. I believe these type patterns are much more effective at breaking up the outline and are as close to ideal as you are going to get for treestand use.
One thing I have noticed about the S&L clothing is that they tend to fade more rapidly than other patterns. I use Sport Wash to avoid odor and fading, but the coveralls seem to fade a little each time they are washed. Just one thing to be aware of.
If I could only buy S&L or Predator Fall Gray, I would be a happy camper.
Have never tried these patterns in the spring for turkey. I always tend to lean in the direction of patterns with a bit more green in them.
