Camelbak Size Guide
Camelbak specialises in premium outdoor hydration gear and accessories designed for active lifestyles. The brand's sizing follows standard UK sizing conventions, though fit can vary by product type. Camelbak products range from performance vests and hydration backpacks to accessories like waist belts, each with specific measurement requirements. Whether you're choosing a lightweight Ultra Pro Vest for trail running or a Kudu backpack for multi-day adventures, accurate measurement is essential for comfort and performance in the field.
How to Measure
- Use a flexible tape measure for accuracy.
- For chest measurements, measure around the fullest part of your chest, keeping the tape snug but not tight.
- For waist measurements on belts, measure around your natural waistline where you normally wear a belt.
- For backpack back length, measure vertically from the base of your neck to your lower back.
- Wear minimal clothing during measurement to avoid bulk distorting your results.
- If your measurements fall between two sizes, choose the larger size for a comfortable fit.
- Consider asking a friend to help obtain precise measurements.

Product-Specific Guidance
Hydration Vests
The Ultra Pro Vest is designed to fit snugly for active use without restricting movement. Measure your chest at its fullest point with minimal clothing. These vests accommodate hydration bladders and gear, so if you're between sizes, opt for the larger size to allow for layering underneath and comfortable pack attachment. The vest provides coverage for trail running, hiking, and mountain biking.
Backpacks and Hydration Packs
For products like the Kudu backpack, back length is the critical measurement. Measure from the base of your neck (C7 vertebra) straight down to your lower back. A properly fitted pack should distribute weight evenly across your hips and shoulders. The S/M size suits most users between 5’2” and 5’8”, whilst M/L is designed for taller users or those requiring extended capacity.
Waist Belts and Accessories
The Stash Belt is a minimalist waist pack for small essentials. Measure your typical belt waist size. Camelbak's sizing allows for layering with outerwear; if your measurement is near the upper end of a size range, consider sizing up to ensure the belt sits comfortably over jackets or thicker clothing. The belt's dimensions are 15 × 40 × 9 cm.
Sizing Tips
- Check product-specific charts: Camelbak offers different size ranges depending on whether you're buying a vest, backpack, or accessory. Always refer to the chart for the specific item you're purchasing.
- Account for layering: If you plan to wear the vest or backpack over a jacket, choose the next size up to avoid restriction and allow comfortable pack adjustment.
- Read customer reviews: Feedback from other users can highlight whether a particular item runs small, large, or true to size, especially for less common sizes.
- Measure in the evening: Feet and torsos can swell slightly during the day due to activity and fluid retention, so measuring later in the day gives more representative results for active wear.
- Allow for hydration system: Vests and backpacks are designed to accommodate Camelbak's hydration bladders. Ensure your chosen size can comfortably fit a full reservoir without excessive tightness.
- Test the fit with gear: When possible, try on your chosen size whilst wearing the hydration bladder, harness straps, or other accessories you plan to use, as this affects the overall fit sensation.
- Contact customer service: If you remain uncertain, Camelbak's customer service team can provide personalised sizing advice based on your measurements and intended use.
