There are lots of comments about people receiving the wrong version of the pad, and only some of them have been helpful. I'll share my experience, in hopes that it gives people sufficient information so they can make an informed decision: TL;DR, if you buy this, you may receive the right product the first time, and Drop will fix it if you don't. First off, it is important to note that there are multiple Klymit products, and Drop has sold at least two of them. The one on this page (Klymit Insulated V Ultralite SL), obviously, but Drop has also in the past sold the (Klymit Ultralight V). Note, that the Insulated V is insulated (giving it the 4.4 R value), while the Ultralight V is not (resulting in a very low weight, but an R value of 1.3). Based on photos and discussions here, it appears that when people get the wrong version, they are consistently receiving the Ultralight V (not the Insulated V Ultralight SL). I reached out to Drop support via email prior to purchasing the pad to confirm the specs on the pad. Drop support confirmed that the pad would be an R value of 4.4 with a weight of 15.2 oz (for the standard size). However, I ended up receiving the wrong pad (the Klymit Ultralight V). I reached out to Drop support with photos of the product I received, and noted my previous correspondence. At that point Drop support gave me a pre-paid shipping label to return my incorrect pad, and then once I sent them the tracking number after shipping the pad, they shipped me the correct pad. My belief is that Drop has both pads currently in their warehouse, and Drop is just making mistakes sometimes when they ship orders (because both pads look nearly identical, and they have *very* similar names). While I was initially shipped the incorrect product and was pretty bugged since I had reached out to them ahead of time and the initial order still got screwed up, Drop did fix the issue and it only cost me delay. My experience is that if you buy this product, you may be shipped the right product; if you are sent the wrong product, Drop will fix it and send you the right product. If you aren't under time constraints, I'd go ahead and buy.

  • Dimensions, inflated (standard size): 72 x 20 x 2.5 in (182.9 x 50.8 x 6.4 cm)
  • Dimensions, inflated (large size): 76 x 20 x 2.5 in (183 x 50.8 x 6.4 cm)

I have a question about this sleeping pad.
According to the details, there are two types of standard size and large size, so what size product can I get if I order now?

Is the R-Value of this pad actually 4.4? Or 1.9 like other comments suggest??
Oct 31, 2020
The large one is 10 cm longer than the short one. 193cm

What's with this Masdrop thing? Did these Bozos change their name or not???

What is the width of the large?
Oct 30, 2020
26" and it weighs 27,6oz (784g) with staffsack instead of advertised 19oz (539g)

What is the actual width on the large. One reviewer says it is 26" wide instead of 20" wide. I really think your company needs to get your spec.'s correct before you sell because the difference is a deal breaker to a lot of people.

Hello everyone, In the description R value of insulated the matress is R4.4 but reading the reviews it turn out that it's a lot lower. Can someone clear this for me? Thank you

You find many discussion about this mat (and the equivalent insulated mat of klimyt) on web (forum and blog). This mat is R1.9 with new standard (and even on old standard, never able to be R4.4).

Can you send me the link to the forum/blog that discusses the "Klymit INSULATED V Ultralite SL" R-Value under the new ASTM standard? I know that Klymit has not updated many of their pads under the new standard, but I find it shocking that they would claim R4.4 and the reality is R1.9. Thank you.

As a reminder, don't forget it's a R1.9 with the new standard and not R4.4 (even with the old standard, this mat never was R4.4, impossible to sleep on snow with).

The discussion on the other drop product was just to tell the new Rvalue published. I know this is not insulated produtct. On massdrop website, you can find Rvalue inside the "Specifications" chart. Weight 16 oz / 454 g Dimensions 72 x 20 x 2.5 in / 183 x 51 x 6 cm Packed Dimensions7 x 4.5 in / 18 x 11 cm Shell Material20D polyester R-Value4.4 WarrantyLifetime As I said, on january, it was writed R1.9 (all forum/blog talking of the new Rvalue take the info from klymit website at this moment)... and I see it myself. Now (since how many time ? don't know, don't checked it since january), they write back R4.4... don't know why.

PS: And this information (R1.9) was consistent with the feelings of people who tested this mattress on cold ground (0°C or less). A R4.4 would be ok for ground of -14°C... this mat is not. PS: Sorry if my english is not good (french are bad with learn langages ^^).
