I have a S2S Journey Jo2 sleeping bag, what would be the best size dry sack for it? TIA
Veronica - Perth(3 years ago)
This will probably depend if you plan to pop the bag in on its own or inside its supplied compression sack. The 13L will suit if you just stuff the sleeping bag into the dry sack without its compression sack, however, you might struggle to compress it. The 20L would be a better option if you're wanting to pop the compressed bag into a waterproof sack. The Medium Compression Dry Sack might be a better option as it will provide compression and keep your bag dry.

Best size for a Biolite1 answer
Want to protect my Biolite, could you please suggest the best size? It’s nesting in the kettlepot. Thank you Snowys
Kirsty - Oxenford (3 years ago)
The 2L size will give you the diameter that you'll be needing, but you'll have extra length which you can easily roll down. Hope that helps.

Hi there What size bag for a regular adults sleeping bag and xl adult bag Thanks
Darren - Duffyâ€™s forest(4 years ago)
Thanks for getting in touch, it's pretty hard to give you an accurate idea of the correct size to chose without being able to see the sleeping bag you have. We'd suggest checking the dimensions of the bag the sleeping bags are currently in and choosing based on that. I would say you'd need at least a 20L or 35L Dry Sack depending on whether the bag in synthetic or down. If you select the size in the drop-down menu it will give you the in-use dimensions so you should be able to choose based on this.

Actual useable capacity?1 answer
The in use dimensions....is that with the top rolled, so the 35 litre version has 35 litres of ‘in use’ capacity (top rolled), thanks.
Brett - Leura(5 years ago)
The Ultra-sil 35L dry sack has a 35L capacity. The in-use dimension length of 70cm is when the bag isn't rolled down. Once you roll the top over a few times it will reduce the total length by a few centimetres.

Hi what size would be best for my down coat. Its size medium women's and regular length. 2 or 4 litres. Thanks1 answer
Gabrielle - Narrawallee (5 years ago)
It's hard to say as different types of down jackets, and exterior materials will compact down to different sizes. It might be best to pop in to try and compact it into a ziplock bag or similar so you can get an idea of the compressed volume, and therefore size of Lightweight Dry Sack.

Please help with sizes ..1 answer
Could you please tell me which size dry sacks I would need for a Sea to Summit SI Comfort Lite Mat (Large) and a sleeping bag with packed dimensions 25cmx17cm (850g). Please advise size to fit both and also individually.
Michelle - Essendon(7 years ago)
I've tried to do a bit of research for you on the shop floor and here is what I've come up with. The 8L sack will fit the Sea to Summit SI Comfort Lite the best. I personally believe the 4L would just be too tight. I'd also recommend the 8L sack for your sleeping bag although you may have to stuff it in. This is a bit harder to gauge though without seeing the bag itself. Working with all this, a 20L sack would be best suited to fit both. I've worked on the basis that it's always best to go bigger than smaller with dry backs as you can always roll the top a few extra times.

What size would be best to place spark III sleeping bag in?1 answer
shane - ARUNDEL, QLD(8 years ago)
Hi Shane, the stuff sack that the Spark III comes with fits 3.7 litres, so the 4L dry sack is probably your best bet.
