Sea to Summit vs Cocoon

Please see my review "Cocoon Vs Sea to Summit" at the Cocoon COC003 product. There a some key differences to consider before you drop your $70 for this liner. Also, the Cocoon is $10 cheaper
In brief, entry and exit on the S2S is not as user friendly as the Cocoon. Also, the stuff sacks are very different and the zipper on the S2S is troublesome whereas the Cocoons' more traditional stuff sack is much more user friendly.
I believe the quality is quite comparable and the dimensions of each are within an inch or two. Because Backcountry is so consumer friendly, you can do as I and get both to compare and take a closer look before making your final decision.
And remember, when returning ask Backcountry for a complimentary return shipping label. They're very generous with that. Thank you Backcountry!

GDay Barry from Sea to Summit here. We read the above review this morning, and were a little confused by it and wondered if the reviewer was comparing like products. So we called our good friends at backcountry.com in order to get a little clarity. As always, they were super-helpful. Heres what happens when you compare apples to apples: Sea to Summits 100% Silk Rectangular Liner costs $54.90. It does not have a side opening. Sea to Summits 100% Silk Traveller Liner costs $69.90. It has a built-in pillowcase *and the first 12 / 30cm of each side are open to permit easy entry* Sea to Summit also manufactures a 100% Silk Mummy Liner with Hood ($64.90) and a 100% Silk Long rectangular Liner ($59.90). *All of the above liners are made of the highest grade ripstop silk available (10 Momme)*. Backcountry.com carries two liners from the other company mentioned in the review; the COC0003 rectangular Travel Sheet ($79.95 in colors, $59.95 in natural) and the COC0009 Mummy Liner ($79.95). Sea to Summit's "Traveller" model would be most comparable with the Cocoon rectangular Travel Sheet that is offered in colors, although ours has the additional pillow case at the top. Our "Mummy liner with hood" would be comparable to Cocoon's Mummy Liner. The zippered pouch is popular with most users; if youd prefer a stuff sack, drop us an email at info@seatosummit.com Hopefully, the above will allow end-users to make an objective comparison between Sea to Summit Silk Liners and other products on the market. Cheers Barry
