These bibs are awesome!! Slide them under your wader and you will not get cold.

If your hunting the late season, I would highly recommend getting a pair. I Wore these with under my waders in 10 degrees and my waders were leaking. Even with it wet, it kept me warm. I only wish they made waders with smaller and larger boot size so I would have to deal with wet conditions

Very comfortable cold weather piece. They make a great under wader warm layer. Very warm and lofty material. Even wore them deer hunting, and I'm planning on wearing them during winter steelhead. Only complaint would be a lack of pockets.

I bought these late last season from a recommendation from a friend and have not regretted it at all. These are about the warmest things I've ever had on my lower body. I've worn them not only under my waders, but in extreme cold under my deer hunting pants. Even though they do not have stirrups they stay down nicely in my waders. The only thing I wish they had were side pockets so that when you aren't wearing your wanders you have somewhere to put you keys and stuff like that. There is one inside pocket that will fit a phone, but that's about it. With side pockets these would be beyond 5 stars.

I just got these and have hunted in them several times. Overall, they are a great piece for what they were designed for. They have kept me good and warm in my waders and reduce the bulk of the Gradient Pants that you tend to get around the ankles which increases the overall comfort. The reason for not giving if 5 stars is that I don't think any thought was given to these being worn before or after the hunt as pants. I've seen several guys including me wear then into a diner after the hunt or just generally running around after a hunt and without pockets, you are constantly thinking, why not? It just begs the question when you wear them. The one pocket they have is in an odd location in my opinion due to the shoulder straps on the bib lining up with the pocket. At minimum, I would have put two of those pockets instead of one. As they are, I would think the pocket would function well for a left handed individual. I'm right handed and the pocket is awkward. Move it to the left side though and now it functions well for a right hander.

Overall great product, but the zipper doesn’t stay up. Very warm, fits great, incredibly comfortable and great for layering with more than just waders. Just wish the zipper would stay up.

These do exactly what they say they will do. they keep me warm in the coldest water underneath my waders. be careful though, once you've build up too much heat, you basically have to strip down to dump heat to avoid sweating. I would love to see a side zipper to account for this. I would also love to see foot straps to keep them from riding up when putting waders, or other pants on. All in all, would highly recommend these to someone who needs serious lower body insulation.

I bought these last season to layer under my Delta waders and they keep me extremely warm. I normally wear pants and merino base layer but when its going to be below 30 all day put these on and have yet to get cold. I'm 5'11" 185 and the size large fits very well.

My only reason for 4 stars is how much it limits my movement when I wear them compared to just pants and base layer underneath my waders. I have a set of large size 10 Delta waders and when I try to bend to kneel down, sit on a short seat, climb into a boat ETC. it makes movement tough in the knee area. Otherwise these are great.

Very happy with the product. I own the gradient pants and gradient bibs. I prefer the gradient bibs underneath the waders and the gradient pants underneath the Dakota bibs. The Gradient bibs are very warm but breath to prevent over heating. I like the slim fit around the ankle, this keeps the bibs legs from riding up my legs and my legs from rubbing in the waders. I am 5’9 190lbs and size large fits me very well.

Nothing pairs better with the waders than these pants. Stood in the water for 4 hours and couldn’t feel the cold.

Bought these to wear under breathable waders and wound up wearing them under pants deer hunting before I had l chance to duck hunt with them. 16° and I was toasty warm. Have since worn them under my waders in sub freezing temps and absolutely love them. They stay in my truck now just in case, lol. Love the warmth, flexibility and light weight. I’m 6’-3”, 260 and ordered an XL - I could probably make do with XXL, but these are fine. Highly recommend buying these if you’re on the fence, you will not be disappointed.

These bibs were my second Sitka purchase and I absolutely love them. They fit perfectly with the heavyweight bottoms and/or a pair of sweatpants underneath. I bought them for wearing underneath my neoprene waders for Wisconsin late season duck hunting (15-30 deg F), but they also work great for under my uninsulated fishing waders for early season trout fishing. I also wear them under my Carhartt bibs for extra warmth while ice fishing and they have yet to let the cold in. The reason for the four stars and not five is because the top zipper does not like to stay zipped completely after moving a bunch or having them under my other bibs. I put a small binder clip over the top zipper to keep them from falling, but it's not a huge deal breaker, but something I would appreciate to be fixed. The fleece is super soft and slips under garments very well, which is a huge bonus. I am 6'3" and 220 and the size large fits perfectly.

New addition this season, great purchase. Makes a huge difference when wearing lightweight breathable waders and standing in water hunting Arkansas timber. Also use them under bibs in below freezing temps while tree stand hunting deer, game changer. I have the light Fanatic Bibs this has made those any season bibs for me. I really like the thin lower leg material for tucking in my rubber knee boots.

Very comfortable and definitely an excellent garment. I do have some criticism. The fact that they don't have a shell creates problems if cockleburs or other debris fall between my waders and the bibs as it gets matted into the exposed fleece. Additionally, without a shell they look weird and makes you kind of self conscious going into the cafe for breakfast after a hunt. Also, stocking stirrups would have been a great feature.

My first exposure to Sitka was five years ago when I purchased a Boreal jacket. Best jacket I own. These bibs are no different. Have been using them multiple times this season and love them. I wear them under breathable waders and have performed great in temps below 20 degrees.

Bought these this year....only used them a few times so far. Already own the gradient pants but much prefer bibs over pants which is why i ordered these. They do not disappoint....these are great and feel like they are slightly warmer than the gradient pants. These bibs are great to layer under waders or hudson bibs
