Quick sizing question- I'm 5'11" and weigh about 140 pounds, but won't have a chance to check sizing at a physical retailer before I order the bag. Would I be fine in the regular size or should I get the long? I have a hard time in sleeping bags that feel tight so I wasn't sure which way to go with the 3S.

Hey Maks,

If you tend to have a tough time with snug sleeping bags, I'd recommend sizing up to the Long, especially if you don't mind the extra two ounces of weight. You'd certainly fit in the Regular, but the Long will give you an extra few inches of breathing room.

Hope this information helps!

Would it be a terrible idea to get the Long even though I'm under 6' tall? I like the idea of keeping my puffy down at the bottom to have a warm jacket to put on in the morning

So long as you are filling that dead airspace of the long it should work just as effectively as the shorter lengths and I see no issue with going with that longer length.

What Wayne said. If you get the long and DON'T fill that space, your feet will get colder more easily. So you're sort of committing yourself to stuffing something in the footbox every time you use the bag, but as long as you're ok with that, go for it.

I am 6'1" and I've tried out the regular in a North Face store. It fits me but I'm thinking it might be a little snug overall. Should I bump up to the long?

Responded on

I would definitely choose a long for you. Like you said yourself, you can fit into a regular but better to have that extra 5-6 inches of space in the long than risk discomfort with a too small bag in the regular.

In addition to you being 6'1'' and getting the extra room for "comfort," one of the additional benefits is room at the bottom of your bag to either put your liners from your boots or additional layers at the bottom of your sleeping bag if you find that you're feet get cold or if you want to put on warm layers in the morning.
