Wore them along with pants winter fishing on the San Juan - mid 20s. Comfortable fit and effective. However, the length of the zipper is an issue. Needs to come down 6" to allow for bathroom breaks.

Can’t wear too large

Sizes large. You have to be seven ft tall to wear a medium

Should have gotten a small.

They run large, very long in the legs the “fly zipper” is located about belly button high. Makes using very difficult. Chest and shoulders are large. So as a base layer they fit more like a middle layer.

most used item next to my waders

not only does this make for an incredible base layer under your favorite Simms wader it is exceptional IMO as a base layer under my late season archery clothing . warmth w/o bulk.

Best for very cold weather

These are just as good as the base layers, perfect fit and comfortable all day. I only bring this one out when it’s really cold.

Awesome layer! Kept me warm in the morning, and as temps began to rise throughout the day , I remained completely comfortable.

I purchased these last year and finally used them this year while Steelhead fishing. I found that they certainly helped keep my warmer but when the need arose to water the plants a true problem showed. I am 6'1", 32" inseam and weigh in at 205. I purchased the xl/ts and using the zipper is a very dangerous operation. Be VERY VERY careful!! The other thing that just frosts me is the "made in China' sign on the tag. COME ON Simms, buy America!!!

Great piece!

What a great piece not only for fishing but other cold weather activities. Keeping the cold off your lower back is something you have to experience to believe. Also, the fit of the medium is perfect for me at 6' 1" with 32" inseam.

It fits very well. It’s not thick and bulky. The weight is good, it doesn’t make you feel heavy. The double zipper is perfect. The only thing I’d say, maybe add a couple inches to the zipper length
