Awesome Mid to Late Season Bib

I'll be honest... I wasn't looking for another pair of bibs this year. I was hoping to find a really great late-season pant, but it seems very few companies are making pants (outerwear) these days, so I researched bibs again. I tried on loads of bibs at various shops, but couldn't find "the one pair" that seemed to tick all the boxes for me. I really wished that I could try on a pair of these before I bought them, but of course, FirstLite is an internet only shop -- I don't think they're on any retail store shelves. Anyway... cut to the chase... I love these bibs. I'm 5-10 and 190lbs and purchased their XL, and they fit great. I can wear these comfortably with just a thin pair of modern sweat pants (not the old school cotton stuff), or I can layer with thicker insulated stuff underneath. I really like the Velcro side adjustments a TON, and the shoulder straps do seem to adjust pretty well for me--though I have them as short as can be adjusted and while that's fine for me, it's really at the end of adjustability. Pockets are nicely laid out, zippers are quiet and very high quality. Fabric is soft/quiet, and I like the additional waterproofing that you can feel on the butt part, where you need it most for those long sits. Really, everything about these bibs is well thought out--you can tell that FirstLite has HUNTERS on their design teams. I'd have to think hard about what to add to these bibs to make them better.

So far, so good.

I’ve hunted in these bibs 3 times now, in temps ranging from low twenties to mid forties (over a week span, but one time same day. Welcome to New England in December.) So far, these bibs have performed great. In the bibs I replaced, I would wear a Marino wool base, sweatpants and the bibs for the colder end of the spectrum temps. For my first hunt in these, with temps down into the twenties, I decided to really test them out and just wear the Marino wool base. I was impressed. At times during my 3-4 hour sit, I noticed my legs get a little cool, but never cold. For walking in the warmer temps, I just opened the leg vents a bit and didn’t over heat. The only slight irritation I have is the stiff leg zippers. Not enough to deduct points, but I noticed it. I suspect I will get used to them or they will break in. I have not tested these in any rain. I’m 6-1, 215 with larger thighs and seat. The XL feels great and I have enough room for sweats on top of my base layer if needed without these bibs looking too bulky. Last but not least they are very quiet and look sharp.

Sanctuary bibs

Very lightweight and comfortable. First hunt was a real test. It was in the 20’s with strong winds and snow. Kept me very warm and dry. Absolutely worth the money.

Best pair of bibs I’ve ever worn! Super warm! I did order one size bigger than I normally wear and they fit perfect. Would definitely recommend these for cold late season sits in the bow stand.

Simply amazing

I have been searching for a new bib and jacket set and decided to go with the Sanctuary set. I absolutely loves these bibs and jacket as well. These are not bulky but plenty warm!! Can't be happier. With my current layering system, everything fits according to size, but the waist is slightly snug where it cinches tighter. May be how the stitching is. It doesn't bind the zipper up or cause problems so certainly not an issue.

I’ve been hunting whitetail in the southeast for over 25 years. The Sanctuary system is the BEST system I have ever owned! Weight, noise, and warmth are better than anything else I’ve tried! I just wore it on a hunt in Mississippi, the temp was 29 and it was very damp/foggy. I was toasty warm with just a heavyweight merino base layer!

Best Hunting Gear I Have Ever Owned

After a cold bow season, I finally decided to pull the trigger on some new outerwear. I had heard from a lot of people I trust that First Lite had some of the best gear on the market, but I still did my research and compared their gear to what other companies had to offer. In the end, I decided to go with First Lite for a number of reasons, such as the fact they designed the gear I was looking for with the whitetail treestand hunter in mind. I ended up purchasing the sanctuary jacket and bibs. I am extremely satisfied with the gear. Aside from being warm and lightweight, what I like most about it is the fact that is not overly bulky, making shooting a bow much easier. Additionally, it is the quietest outwear I have ever worn. I snuck up on several deer my first day out in it. Overall, I could not be more pleased and would recommend these products to anyone.
