Issued UCP Bivvy Bag
Description
On the trail or in the field, keeping your kit as lightweight as possible matters. Perfect for backpacking, bikepacking, or just trying to experiment with your camping gear, bivvy bags are an increasingly popular ultralight shelter for lovers of the outdoors. Part of the U.S Army's "Modular Sleep System", these bags are an affordable alternative for anyone trying to turn their sleeping bag into a robust three-season shelter.
The Short and Sweet:
- Authentic USGI
- Water resistant
- Compatible with USGI MSS sleeping bags
- Waterproof + vapor permeable 3-layer laminate shell
- Sexy UCP camouflage
- Light weight
- Made in the USA
A Gorp-core Favorite:
These bags are not branded as Gore-Tex tech; that said, these bags consist of a three-layer laminate shell many outdoor enthusiasts are quite familiar with. They feature a simple zipper and snap points for a USGI bag. Constructed in much the same way as that expensive Patagonia jacket you bought and never use. Wet pits or wet fart, doesn't matter; the material allows your stinky and uncomfortable body vapors to escape while keeping rain and water out.
Who needs it?:
A great alternative or complement to your standard shelter system, these bivy bags are authentic USGI issue, coming in surprisingly good condition. These bags fit easily around almost every sleeping bag. Super lightweight and super easy to pack, you'll almost forget you packed your bivy at all. These are perfect for anyone looking to experiment with ultralight/lighter-weight outdoor gear.
Bonus points for being in the greatest camo pattern ever made.

Curious About Sizing?
Given the massive variety of clothing we carry, a standard sizing guide is incredibly helpful for customers seeking the best fit.
Please understand that surplus varies widely in fit and cut and this sizing chart is general advice rather than tailor-level fitting.
Nearly every military has different sizing charts and schemes, which is why we've taken the time to put together this brief tutorial.
Jacket & Shirt Sizing
In absence of an established military size chart, we measure each jacket or shirt from armpit to armpit to get a rough idea of how it fits. If a garment is between sizes, we mark it one size down. For example, if a shirt measures 19.75" from pit to pit, it is marked as a small rather than medium.
To measure pit to pit, close up your shirt or jacket and measure from armpit to armpit.
This is our measurement guide that we use to measure garments without an existing military size chart:
14"-15" PtP = XXS
16-17" PtP = Extra Small
18"-19" PtP = Small
20-21" PtP = Medium
22-23" PtP = Large
24-25" PtP = Extra Large
26-27" PtP = XXL
28-29" PtP = 3XL
Pant Sizing
We typically convert pants to US waist and inseam sizes. If a pair of pants is between sizes, we mark it one size down. For example, if a pair of pants measures as a 33 waist, it is marked as a 32 waist.
To take these measurements we lay a pair of pants flat on the ground. We then measure across the waist and double the measurement. For example, if a pair of pants measures 16" across the waist it will fit a US 32 waist.
To determine inseam we measure from the crotch seam to the bottom of the cuff. For example, it a pair of pants measures 30" from the crotch seam to the bottom of the cuff we will list it as a 30 inseam or 30L.
