G'day David,

The compression sack for the Long is the same as the Regular - Large which is 20L compressing to 6.5L
Hope that helps!

G'day Matthew,

Yes, you can use the Basecamp Bc3 inside a 90cm wide swag, that won't be a problem. They can be rolled up and stored with the swag, just be sure to store your swag somewhere where the temperature won't fluctuate too much, and where there isn't any risk of damp. The Regular length bag is designed for people up to 183cm tall, so you're on the cusp, but the bag should just be long enough for you.

G'day Steve,

Yes you can join two of these Basecamp bags together to make one double-sized bag.

G'day Jenny,

The size of the compression bag for the BcIII - Regular is a Large, 20L down to 6.5L compressed.  You can see a photo of the size comparison against a 1L Camelbak bottle in the last of the product images.  We do have all the Sea to Summit Sleeping bags our our upcoming videos, so watch this space.

This bag is a unisex bag, so in terms of the unisex regular fit for length, you could look at the other Sea to Summit bags Ben has reviewed for a general indication.  In terms of overall space, this bag is designed for unrestricted sleeping, with loads of room for moving around and curling up, etc.  Its the most similar to quilt sleeping, but inside a bag!

G'day Ann,

Yes it does. The BcIII comes with a L (20>6.5L) compression sack.

G'day Ann,

Yes, you can join together two Basecamp BC3 Sleeping Bags, with one regular length, and one long length. The side zippers are the same length so they can be joined together and then one side will have a slightly longer foot box length.
