It does over on Dogfunk.

The sizing chart says the XL is for a 40-42 inch waist. Yeah, that sounds way too large for you.

I wouldn't worry as much with an insulated boot. You are right that sizing does vary slightly from manufacturer to manufacturer, but insulated boots will never be as precise of a fit as other types of footwear. Based on reviews, I went up half a size in the pull on version of these boots and found that they're a good fit with thick winter socks. That said, I probably could have gone with my regular size. If you sometimes have to size up, then I would size up in this boot just to be safe.

As for a direct answer to your question of how sizes are calculated, each manufacturer calculates them slightly differently. If it's a real concern that you'll get the wrong size, then try to find them locally. Or you could order from Zappos since they pay for shipping on returns. However, they only take returns for unworn shoes. Backcountry has a much more liberal return policy.

The GSI Bugaboo set I just bought may be what you're looking for. Comes in three sizes.

It fits true to size, and the length is probably on the longer side. Not abnormally long, but not short.

I would say yes. The large ones from last season fit me well, but this one was tight in the chest. I returned it and should have an XL waiting for me on my doorstep when I get home tonight. I hope it's not too long.

It's 12 oz or 340g. This jacket is very packable but it doesn't come with a pouch and I've never noticed that it packs within itself. I always just wad it up and throw it in my pack.

That sounds about right. I'm 6'1" and 175 lbs. The large fits me perfectly.

Yes, but it's not as simple as that. At a minimum you'll need to attach 3/4" plywood to your studs that you can then attach the holds to. Here's some information from Metolius on how to properly build a climbing wall.

Inseam and length are the same thing. The order is waist x inseam. That's always the case for pants.

I'm guessing it would float as long as you don't put anything absurdly heavy in it, but you can lash it down to keep it from going anywhere.

Looks like a 22 according to the confusing sizing chart.

From the tech specs section, "Interchangeable Lens: Yes,(sold separately)"

Yes

From Teko's website: Small = 4-6, Medium = 6-10, and Large = 10-12.

You mean besides right here?!?! Looks like most sizes are in stock.

I don't know about a minimum chest measurement for it, but I went to Carhartt's site to get their sizing chart. Hope that helps:

XS = Size 0-2, S = Size 4-6, M = Size 8-10, L = Size 12-14, XL = Size 16-18

L/XL is also currently available

I just got the jkt (shift-composite black/cinder) today, and as far as i can tell it is powershield all around the exterior. The black part has a slightly thick fleece interior vs the cinder which is a thinner fleece interior. The black part also felt slightly more rugged...probably for backpacks and bushwacks. I ran the sink hose on both sections and they seemed equally water resistant. The thinner fleece under the arms may aid in breathability.

This seems similar to the marmot superhero in that it has 2-3 different interiors based on function.

Bottom line...i'm happy with the purchase (power shield, made in Canada, good fit(still need to wear it though).

You can always order it w/ free shipping. Worst comes to worst, it'll cost you a few bucks to return.

EDIT:
This is not all Power Shield. The panels are Power Stretch. I have not touched the Shift, but I expect it is entirely Power Shield. The "black part" is Power Shield with wind and water resistance and insulation. The "cinder part" is Power Stretch which is just smooth surface, stretchy, non-wind and non-water resistant fabric. It offers high breathability and stretchy ease of movement. I asked several times and the folks there seemed to think it was Power Shield, but after it arrived, it was easy to tell the difference, and they were happy to pay for the return since it was incorrectly described.

**********
This is someone else, so I left the original info intact and thought I would clear this up.
I just got off the horn with them guys at Backcountry, and found out that the Composite, is Powershield with panels that are powerstretch. It sounds like to me that it would make this one better for more athletic activities and easier range of movement.

From what I know of these materials they are all treated the same way with DWR so they should be just as waterproof as the other, but this has more stretch but not as warm as the normal Shift.

Also if you want info on the different materials check polartec.com and it is all there so you can see differences.
Know you know, and knowing is half the battle.

The Tech Specs say 24 oz.

No, you're not the only one. My friend the other day was saying the same thing. So there you go, now you finally have something in common with someone.

Interior height is listed as 140cm (or 55in)
