This review is from 11/15:
I wore the Sylo Natural softshell pants for 2 days last week. Light polypro base layer underneath. Temps 10 degrees to high 40s. Excellent pant, warmer than Sitka 90%, which I wore the 3 days before in slightly warmer temps. Sylo pant is a softshell exterior, so is louder and stiffer than the 90%, not an issue for rifle hunting. It has a grid-pattern fleece lining, warm and breathable. I zipped open the crotch vents a few times when walking during the warm part of the day, which cooled the jewels. I did not use the suspenders; a belt held the pants up, even w a lumbar pack around my waist, so the rubber waist gripper worked well. More pockets than the 90%, and the hip pockets are much deeper, so stuff doesn't fall out like it did w the 90%. Sylo pant has 12" zippers on lower legs to take off over boots. I removed the knee pads for this hunt as I was not crawling. Bottom line, I'm keeping these pants for use during later seasons, and will try them w no base layer during warmer hunts.
Fit note: 34 regular fit me perfectly w base layer. 5-11, 170, 34 waist, 32 inseam. Not tight, not baggy.
