For running I would probably go with the Marmot, reason being the Alchemy is not as breathable and is more for protection than breathability. Like Ian said the Marmot might be a little cold if your just standing around. Hope this helps!

This bottle should have the new liner in it but if for some reason it doesn't Sigg will replace it for you with the new liner.

There will be no damage done to the bottle or lining if hot beverages are placed in it. The damage will probably happen to your hand when you touch it. There is no insulation in the bottle so what ever temp. the liquid is thats the temp of the outside of the bottle.

THIS IS NOT AN INSULATED SHELL! It is strictly a shell and designed to layer under it.

I went for the SV because you never know what situation you will find yourself in and in my eyes tougher is better and worth the extra money!

Hey I am your exact size and I have the Medium. It fits great and like cash and brandon said there is room to layer. If you went with the small there would not be enough room to wear a fleece under it. Go with the medium. Hope this helps!

I am 5'9'' and 165 lbs. I have the medium but I layer with a thick fleece or down sweater. If you plan on using one or two thin layers I would go with the small. My only hesitation would be on limiting yourself on how much you can layer in very cold weather. Hope this helps!

As far as simmering I believe they are very similar, it all depends on the amount of pressure you have in the bottle, and MSR has perfected the flame control on the whisperlight. I may be a little biased since I have had my whisperlight since '98 and it is still going strong, but I would go with the whisperlight if you are going for a reliable stove that will out last any other piece of camping equipment you own. It is easy to clean and it has worked in every condition I have thrown at it. Hope this helps!

The Small is TSA approved.

I would agree with Dave, The Large sounds right up your alley. Remember there are straps on the side to cinch the duffel down if it is not full all the way. Hope this helps!

The large is the most practical, since there are straps to cinch down the bag if it is not full all the way. I would go with the large. And the Extra large is HUGE!

I agree a Large would probably fit you great.

As I said, it all depends on the activity you are going to engage in. For arobic activities you dont really want a jacket that doesnt breath. I love my Windstopper MH soft shell for everyday use, but it doesnt breath in heavy activity. The Gamma is very breathable and has a diffrent purpose than these other jackets.

The Shift is a good jacket but get it on sale, I agree with Ian on that point. It is a bit pricy but it is on sale alot, or you can catch it on steepandcheap.com sometimes.

As far as the Apex Bionic, I would say about it being the standard I would agree to a point. That is because EVERYONE has one and you can pick one up almost anywhere. It is a great jacket for going to school, grocery store, ect. It all depends what you plan on doing. Hope this helps and further clarifies my previous post.

I have the medium and my arms are average length,(31'') and the sleeves are a little long for me. Hope this helps

The 1L bottle weighs 5 oz. and the .6L weighs 3.5 oz. Hope this helps.

Wash the bottle with vinegar and water, they also make a scrub brush that works great for these bottles. And no OJ will not hurt this bottle at all nor you. There is a backed on liner inside the bottle that is pretty much impenetrable. Hope this helps.

The differences are the Gamma is a very breathable fabric, not very windproof and only water resistant. The shift is a more "sealed" jacket. Much more windproof and waterproof (not a 100% on either) but not as breathable. The Apex is a city/non technical jacket. Hope this helps.

It all depends on what you are using it for. For aerobic activities go with the Gamma LT. For Every day use and a more all around jacket go with the Shift. This is all based on the breathability of each type of fabric. Hope this helps.

-8 degrees celcius is 17.6 degrees fahrenheit. So a 15 degree bag would be just fine for those temps. Hope this helps

I don't believe this has a liner like the apex. This is more for warmer weather, a much more breathable jacket. Ideal for high activity. Hope this helps.

The small would probbobly fit you well. I am 5'9'' 160 and the medium fits me well. Hope this helps.

This jacket is very breathable, no it is not windproof.

My jacket is made in Canada and the quality looks the same as the China made ones. But honestly the Gore-Tex material has probobly been made in China for a while.

XL would be perfect if you want to layer a little.

Im 5'9'' 160 and the medium fits me great. I think the medium would be perfect for you. Hope this helps.

Jon is right, if you get too hot with the Alchemy a little unzip will cool you down. It is a great jacket.

It is the diameter. And if you roll it up tight with the valve open it gets even smaller than that.

Jason is correct on that. It only can be used on the 25.

This bag is a 3/4 length and it is a two way.

It states in the description that there is a windscreen and all the accesories desctibed. Not sure why others state diffrent. The accesories come with the stove from MSR. Its a great buy!

I am 23 and I own a Mountain Hardware Alchmey soft shell and LOVE it! As far as the two you have mentioned I would go with Marmot. It looks better and most of all it out performs the TNF.
